Synology DS1525+ vs DS1522+ NAS Comparison – Get It Right, FIRST TIME!

With the arrival of the Synology DS1525+ in 2025, many users are now weighing it against its immediate predecessor, the DS1522+, released in 2022. On the surface, both NAS units share the same 5-bay form factor, nearly identical chassis design, and very similar price points—typically between $699 and $799 at launch. However, a deeper dive reveals a number of meaningful changes in hardware resources, storage expansion policies, and how Synology now handles drive compatibility and system flexibility. While the DS1525+ does offer better networking and CPU core count, it also introduces tighter restrictions on what drives can be used, how storage pools are formed, and what options are available to users looking to migrate data from older systems. By contrast, the DS1522+ retains a far more open approach to hardware, offering greater freedom for enthusiasts and IT professionals. In this article, we’ll break down the internal hardware, ports, storage support, DSM software capabilities, and system behavior of these two NAS systems—giving you the context you need to make the right decision the first time, and avoid buyer’s regret later.

Synology DS1525+ vs DS1522+ NAS Comparison – Internal Hardware

The most noticeable hardware difference between the DS1525+ and DS1522+ lies in their processors. The DS1522+ is powered by a dual-core AMD Ryzen R1600 CPU, which operates at a base frequency of 2.6 GHz and can boost up to 3.1 GHz. This chip delivers strong single-threaded performance and is very power efficient, making it well-suited for environments where tasks are sequential or lightly parallelized—such as SMB file sharing, surveillance, or general-purpose storage. The DS1525+, in contrast, uses a quad-core AMD Ryzen V1500B processor running at a fixed 2.2 GHz. While it lacks boost frequency, the additional cores and threads make it the more capable option for multitasking-intensive DSM deployments. Workloads like hosting multiple Docker containers, running several VMs, or operating high-volume backup jobs are handled more smoothly by the V1500B thanks to its stronger concurrent throughput. While synthetic benchmarks might show the R1600 ahead in single-threaded operations, in day-to-day NAS usage, the V1500B’s multitasking benefits are more relevant—particularly for users aiming to centralize many services on one box.

Beyond raw processing and RAM, the DS1525+ also refines power and noise efficiency. It has a slightly lower noise floor at 22.60 dB(A) compared to the DS1522+ at 22.90 dB(A)—a small but welcome reduction for those placing the NAS in workspaces or home offices. Power consumption is another area of subtle improvement. The DS1525+ draws just 44.56 watts under active use and 13.63 watts in HDD hibernation, making it more efficient than the DS1522+, which consumes 52.06 watts and 16.71 watts, respectively. This improvement may be attributed to internal board optimizations and more efficient firmware tuning. Physically, both NAS systems share identical chassis dimensions, cooling layout, and component arrangement, including dual 92mm fans for thermal management. In sum, while neither model introduces radical hardware changes over the other, the DS1525+ provides a better balance of multitasking power and efficiency for modern DSM deployments—particularly when scaling beyond light usage.

Synology DS1525+ vs DS1522+ NAS Comparison – Ports and Connections

The differences between the DS1525+ and DS1522+ become more apparent when examining their networking and expansion connectivity. The DS1522+ is equipped with four 1GbE RJ-45 LAN ports, which support link aggregation for up to 4 Gbps combined bandwidth when used with a managed switch. This configuration provides solid redundancy and flexible port allocation, especially for environments where isolating traffic across different services (e.g., backups, media, surveillance) is desirable. However, in 2024 and beyond, 1GbE is increasingly viewed as a bottleneck—particularly for users working with 4K video editing, large VM images, or fast local backups. The DS1525+ addresses this issue by shifting to 2 × 2.5GbE RJ-45 LAN ports, allowing up to 5 Gbps total bandwidth through link aggregation, and faster speeds on a per-connection basis, even when using unmanaged 2.5GbE switches that are now more common and affordable. This change aligns the DS1525+ with modern mid-tier NAS expectations and offers improved real-world performance, especially for multi-user workloads and high-speed transfers from SSD caches or NVMe pools.

Additionally, both units include a PCIe Gen3 x2 slot for optional 10GbE network upgrades. Synology’s E10G22-T1-Mini card is supported on both models and provides a compact, cost-effective way to future-proof network performance. However, given the DS1525+ already starts with 2.5GbE, users may find less urgency to upgrade immediately compared to the DS1522+, where a 10GbE card may be needed sooner to break past 1GbE limitations. Both models support Wake-on-LAN and scheduled power events, and both feature dual rear fans for effective cooling regardless of network traffic or drive load. From a connectivity standpoint, the DS1525+ represents a forward step toward higher-speed networking and modern expansion methods—but it does so at the cost of legacy compatibility, which may matter for users with established infrastructure. In contrast, the DS1522+ offers broader port coverage and flexibility but risks becoming dated more quickly in high-throughput environments.

Synology DS1525+ vs DS1522+ NAS Comparison – Storage

At first glance, storage capacity and physical layout appear virtually identical between the DS1525+ and DS1522+. Both systems offer five main drive bays that support 3.5″ SATA HDDs and 2.5″ SATA SSDs, as well as two M.2 NVMe SSD slots for caching or, in the case of the DS1525+, full storage pool creation. Each NAS can be expanded up to a total of 15 bays using two proprietary Synology expansion units (DX517 for the DS1522+, DX525 for the DS1525+), enabling up to 240 TB of raw storage assuming maximum capacity drives. However, a major divergence emerges when we examine drive compatibility policies. The DS1522+ follows Synology’s older, more permissive approach: users may install third-party drives from brands like Seagate, Western Digital, or Toshiba with only warning messages shown during setup. Storage pools, RAID arrays, and DSM installation all proceed without functional restrictions, making it a flexible platform for users with existing drives or cost-sensitive deployments.

Synology DS1525+ vs DS1522+ NAS Comparison – DSM Capabilities

Both the DS1525+ and DS1522+ run Synology’s DSM 7.2 operating system and provide access to the same broad library of official and third-party packages. This includes core applications such as Synology Drive for file sync and access, Synology Office for collaborative documents, and Active Backup for Business for system-wide backup management. The app experience is largely identical on both devices, with support for Virtual Machine Manager, Hyper Backup, Snapshot Replication, Synology Photos, and Surveillance Station. However, the differences in system hardware and compatibility enforcement subtly influence how DSM behaves and what features remain available under different configurations. For example, both models support up to 256 snapshots per shared folder and a system-wide maximum of 4,096 snapshots, but users on the DS1525+ will be subject to stricter compatibility enforcement in DSM’s Storage Manager if using drives that aren’t on Synology’s approved list.

Synology DS1525+ vs DS1522+ NAS Comparison – Conclusion

The Synology DS1525+ and DS1522+ may look nearly identical on the outside, but they diverge sharply in philosophy, system behavior, and long-term value. The DS1522+, launched in 2022, stands as one of the last truly flexible 5-bay NAS systems in Synology’s portfolio. It offers a dual-core AMD Ryzen R1600 processor with excellent single-thread performance and supports up to 15 drives with two DX517 expansions. More importantly, it retains the traditional Synology approach to third-party drive compatibility—meaning users can install and operate a wide range of HDDs and SSDs (Seagate, WD, Toshiba, etc.) without system blocks. DSM will issue warnings if a drive isn’t officially listed, but critical features like RAID recovery, storage pool expansion, and hot spare assignment continue to function. That level of hardware openness makes the DS1522+ particularly attractive to power users, budget-conscious builders, and small IT teams looking to repurpose existing hardware. The DS1525+, released in 2025, represents a subtle but significant shift in Synology’s design strategy. On paper, it offers solid upgrades: a quad-core AMD Ryzen V1500B processor that enables better multitasking, faster 2.5GbE LAN ports for improved data throughput, lower noise and power consumption, and full NVMe storage pool support (with Synology SSDs). These improvements make the DS1525+ a better fit for users running multiple simultaneous services—such as Surveillance Station, Synology Drive, and Docker containers—all while maintaining smooth operation. However, these benefits come with stricter limitations. The unit enforces Synology’s 2025-era drive verification policy, which outright blocks DSM installation or RAID operations with unverified drives. Migration is allowed, but users will be met with persistent warnings, degraded system status indicators, and feature restrictions that can’t be bypassed. The flexibility to reuse older drives, expand arrays freely, or mix hardware brands has been systematically curtailed.

In essence, the choice between these two NAS systems reflects more than just performance—it’s a decision between openness and control. The DS1522+ remains a strong all-rounder for users who want to build their system on their own terms, manage diverse storage needs, or repurpose hardware they already trust. It’s well-suited to small businesses, creators, and experienced users who value transparency and adaptability. The DS1525+, by comparison, is more refined, but also more prescriptive. It favors users willing to commit fully to Synology’s ecosystem—those who prioritize simplicity, tighter integration, and long-term consistency, even at the expense of flexibility. It’s a better fit for turnkey environments where reliability and vendor support matter more than customization. Both NAS devices are excellent in their own right, but the right choice depends entirely on how much control you’re willing to trade for convenience—and whether your NAS should be a platform you shape, or a solution that shapes your workflow.

      1. This basically kills off the feasibility of upgrading from an old model if currently using third party drives.

        A) It means that even if a third party drive is under warranty, a replacement would be rendered useless.
        B) If you have to replace a third party drive, you’ll end up with an array with different brands, which is something Synology seems to be against now, after years of it being one of their great selling points.

        I hope my six year old DS418Play lasts a good long time. I had been planning on upgrading, but its eventual replacement will not be Synology unless they undo these ridiculous changes.

        I’m having a hard time figuring out Synology’s logic here, but It’s my guess that they predict not being able to stop the loss of SOHO customers to the likes of UGREEN and won’t reduce their prices to counter that, so have decided to drop that sector and gouge the corporate realm.

      2. Synology will achieve its goal of fewer support calls with this strategy. When no one buys the product they won’t call for support. I will never upgrade to one of these new NAS.

      4. Wow, still making excuses for this scumbag company. There is zero reason for them not to have other drivers verified before releasing. They are the worst anti consumer pile of crap company. At this point, there is nothing that Synology can do to get back as customer. I do not know what brand NAS my replacement for my DS1815+ will be but regardless what anti consumer pile of crap Synology those it will not be a Synology drive. They have proved that they will screw over the customer. That coming from some that had a Synology router. Has deployed Synology NAS at work. Has recommended Synology as a company for years. I cannot believe you’re still making excuses for this pile of crap company. There is zero reason to release a new NAS and not test any driver but their own before launch, other than to milk the customer for as much cash as possible.

      5. Appreciate the work. Was already convinced I was leaving but now I have new concerns about what to do if an older Synology dies and the drives need to go into a newer unit. That’s data loss territory! Exactly what your NAS vendor should NOT EVER be baking in. Screw ‘em. Bye.
        REPLY ON YOUTUBE

      6. You must be aware that the compatibility check can be disabled ?
        Can we form an orderly queue for you to add this feature . . . for the less tech advanced people ?
        REPLY ON YOUTUBE

      9. Who buys Synology products anymore? Compared to their competition Synology products are overpriced, use outdated technology (i.e. ancient CPUs), have artificial limitations (i.e. no 10gb NIC, extremely limited USB devices support) and now lock HDD compatibility to Synology drives only.
        REPLY ON YOUTUBE

      11. Synology has tested and supported many Seagate western digital drives for years

        They clearly do not want to add these to the list, to maximize their profits

        If they add any, it will simply be due to pressures
        REPLY ON YOUTUBE

      14. Good bye Synology. I’ve used your products both personally and professionally in my own personal business, I’ve deployed them to TONS of customer sites, and I use them currently in my daily profession in Public Safety. After your recent anti-consumer policies and unsupported 3rd party hardware I am going to migrate ALL of my products and services to pfSense and TrueNAS and my own hardware.

        R.I.P. Synology. It’s been real, it’s been fun, but a HUGE mistake on your part and it’s going to cost you thousands of customers most likely more.

      17. Can you still use these units to run the plex media server as its main purpose?
        This is what I use my DS1520 for (the last one with Celeron processor).
        REPLY ON YOUTUBE

      18. Though I understand and appreciate why you need to cover the new 25+ range from Synology, I think most here have lost all interest in this new series. Synology have killed the appeal of any of the new 25 range due to their insane drive lock in policy. This new restriction, in my opinion, made all the DSxx25+ range of Synology NAS’s DOA.
        REPLY ON YOUTUBE

      19. I’ve been waiting 18 months for the 25+ series to arrive so I could upgrade my DS420+. After considering all of my options, I bought an 1821+ so I could easily migrate my existing SHR1 drives. This is likely my last Synology purchase. Who knows if this company will even be around in 5 years. I’ll figure it what to do then I guess.
        REPLY ON YOUTUBE

      20. They seem to have bigger agenda with this. They want us home and SOHO users to be mad and leave ship so they can stop making home NAS boxes and focus solely on the enterprise market.
        After 15 years I’m fed up with their policy and moving away to Qnap and QuTS Hero.

      21. My journey with multiple Synology NAS units, spanning well over a decade, appears to have met its end. The DS918+ will have been my last Synology product.
        REPLY ON YOUTUBE

      23. I really enjoy your videos and over the years find them informative, but no matter how you cut it Synology just isn’t trying any longer. Yes the drive lock issue does bother me for my home use for my business use I don’t have a huge issue with it. My issue now is really hardware doesn’t change enough for 7+ years on average and the software just stopped being enhanced 3-4 years ago when they did a huge push for cloud addition. It feels like all software efforts have moved to their new line of units vs shaping the current product.

        They are more than welcome to go down this path but for me and what I spend my time learning and following Synology is starting to fall off my list.
        REPLY ON YOUTUBE

      25. Excellent presentation. Thank you. I know these 2025 new release Synology videos are going to be hard to make. It will be interesting to see if they hold their line tight or change directions over the next year. Either way, they are a no-go for me moving forward.
        REPLY ON YOUTUBE

      27. Thank you for such an in-depth overview of the scenarios, very useful indeed. As a reseller of Synology devices this was disappointing news, I have been selling Synology NAS’s for years and are my go-to NAS, for now I will not be recommending the newer models and stick with the older series which do support 3rd party drives, while they are still available. Hopefully Synology will work with the 3rd parties such as WD and Seagate to make their products certified in the future. Otherwise there are other NAS vendors that their customers will move to and their sales and reputation will undoubtedly suffer.
        REPLY ON YOUTUBE

      29. Synology warns users that Kingston, Samsung, WD, Seagate, and SK Hynix are at risk. This is a direct confrontation between Synology’s own brand value and the above storage device manufacturers.

      30. Sorry that I couldn’t watch the entire video Robbie but I did give it a Thumbs Up. My in-laws are arriving in the next hour or so and I have to move my 8 bay QNAP into the guest bedroom and get the nightly RAID scrubbing schedule set before they get here. Cheers mate… ( PS, to enhance the effect, put your spare change and keys in a ceramic dish and leave that on the top of your NAS. Works wonders.)

      34. I think you need to move away from being a synology yes man and start covering other manufacturers a lot more as they are the future, synology isnt. The hardware is crap in comparrison ot others and its software while good is just stagnent.

      43. I bought a 1522+ in January of this year. I prefer having the 4 x 1Gb ports because I still have a gigabit switch internally, plus I have multiple VLANs so it makes it easier for bonding and for the VLANs. Although I use Synology drives, it’s nice I have the flexibility to use non-Synology drives in the future if I want to.
        REPLY ON YOUTUBE

      46. yep OLD, technology, this shoulda been out like 5 years ago!! the competition is WAY ahead, and is not requiring “their” HD’s, no thanks!!!
        REPLY ON YOUTUBE

      47. Here’s a disturbing thought…. Blocking non-validated drives is based on a ‘whitelist’ of ‘validated’ drives. That automatically means that somewhere on the NAS there’s a file that contains that list. What if that file gets corrupted? What if some Synology employee makes a booboo and puts a typo in there? What if there’s a ‘soon to be ex-Synology employee with a grudge’ who does that on purpose? And those corrupt files slip through QA? Things like that happen, and no matter how hard Synology is going to say it won’t I know it can, and probably will happen at some point. That might render your NAS unusable, or at ‘best’ cause you to have all these non validated drive issues with drives that might be perfectly validated and otherwise good. Artificial blocking in such ways is a recipe for disaster.

        Mind you, I totally understand validation of hardware for vendors of NASes, and such. I have absolutely NO problem with them doing that. They have to keep their support costs under control (or charge the customers with the difference, which will make them much more expensive, etc). But this is just a stupid implementation of this policy.
        REPLY ON YOUTUBE

      51. Synology would have been much smarter to just license their software to any DIY nas device. As it stands now there is zero reason to update to a unit with sub par specs with a software that enforces terrible HDD choices at a premium.

      71. I was wondering if that script that adds your drives to the “compatible list” works on the ’25 units, and if that’d be a way around the migrated pool and a drive failure/adding same disk test?

      74. Yikes!! Whoever pushed and shoved this decision through at Synology is probably doing a lot of “short selling” (or buying some major “put options”) in anticipation of the Synology stock tanking and taking a nose dive in price. Not so crazy, actually, Brilliant! Although, Really bad for the corporation. Oh yeah, and the consumer. Or at least what’s left of them. Major opportunities for other NAS competitors. And NASCompares.

      76. Synology would like to thank you for being a loyal customer for years. So now when your Nas dies, you can purchase a new updated Synology NAS and all your hard drives all over again. You are welcome, its the least Synology can do to show you how important you are to them.

      88. Wow. This really sucks. We need an open source software that does SHR. Drobo’s had something similar and I went to Synology because they also allowed mis-matched drive sizes in a NAS form. Unraid and Hexos does not do a variation of SHR which is sad.

      94. The 2025 Synology series is unfortunately Dead to Me. I have a DS423+ (Plex user here) and there is zero reason to ‘upgrade’ to the 2025 models regardless given the HW specs. This is a pity as the DSM 7.2 version I’m on (before they removed Video Station) looks to be the version I’ll be staying on as long as I can (baring some significant security issue).
        REPLY ON YOUTUBE

      95. I’ve been a loyal Synology user, and this is my third unit, but it will also be my last. It feels like Synology has forgotten who their core customers are. Casual users generally don’t care about NAS, while power users, who set everything up for their families, care a lot about flexibility and choice. Forcing users to buy only their drives is where I draw the line. I’ve always used IronWolf drives and have been completely satisfied with them. I’m not going to switch just to comply with Synology’s new restrictions.

      96. Stability is great. But let me choose. If you want to verify drives which guarantees me a certain level of stability, great. It’s my device though so if I want to put in different drives and don’t give a shit about your verification, then I should be able to.

      97. We’ve had an eight unit Synology NAS in our office for several years and have been waiting on the release of the 2025 model to upgrade this. The company’s decisionn to force users to buy their rebranded drives has sent me looking to their competitors.

      101. LOL. @Synology, get over yourselves. You’re not even close to enterprise class devices, stop LARPing. I was looking at replacing my fleet of aging Netgear ReadyNAS 4, 6 and 8 bay enclosures and @Synology you WERE on the list. Now, you’re #1 on the “Hard no” list, as I don’t/can’t trust you, even if you roll back this greedy decision.
        REPLY ON YOUTUBE

      103. They should’ve just raised the price instead of lock it. They want to fight HDD prices falling locking you in and tap into HDD sales. I was looking for a 10 bay and due to lock in I’m passing. I need to be able to move old RAID designed drives over not buy 10 new ones. This also forces you to buy bigger drives up front. I will not be buying one of their products. I have 86TB and will be growing 24TB a year. So who is this product for?
        REPLY ON YOUTUBE

      104. I have worked the industry an I can understand the idea behind Synology’s decision to ban drives that are not on the HCT list. I can understand, but I don’t think they did it the right way. The right way would be to expressly state that if you are using drives that are not on the HCT list Synology will not accept any warranty claims in case of disk failure, array failure or data corruption.

        The reason I say this is because I have built a lot of storage servers and run into disk compatibility problems. In one case WD shipped over 200 drives so we could swap out the drives that failed in the servers a customer bought. Thing is these drives were actually on the compatibility list, but then using an older firmware. Once the firmware was upgraded the disks were no longer compatible. In another case I had to sit at a customer and update the firmware of about 100 drives as the R6 arrays had failed. This customer had all error mail messages sent to an employee who never looked at them. Had he even just looked at the servers once he got an email he would have seen the error LED on the failed drives and the array failures could have been prevented. As it was the drives failed, the arrays were degraded, the standby drives were used to rebuild the array and another drive failed and the second standby replaced it only for two more drives to fail and the arrays were dead. This is when they called about the problem. Seagate and the controller manufacturer went through the logs from the controllers and Seagate provided a new firmware that solved the failures. These are things you don’t have to deal with if the drives are tested, certified and the drives you buy has the correct firmware. And to get the kind of service we got from drive manufacturers it helps if you are talking about several hundred drives at a time. It’s harder to get prompt service if you are a end user and have four or eight drives that cause a problem.

      108. What about older non-Synology drives?!
        I have an old DS414 that I’d love to replace but was waiting for 2.5Gb network. Now I’m just a home user, I don’t have a big budget, so if I replaced my NAS, I would want to use my existing old (but working perfectly) drives, preferably with a clean install after backing up the data. I’ve no idea if these old drives are on any recent compatibility list even if Synology were to open up the allowed list a bit.

        And these NAS units aren’t cheap, there’s no way I can afford a new NAS and 4 new drives all in one go, and then what happens to my existing perfectly working drives?

        I just can’t see how I can buy a new Synology NAS now.
        REPLY ON YOUTUBE

      110. While it’s unofficial fixes, i would really appreciate it if you could test some of the HDD compatibility scripts (hacks), which replaces/expands the file which contains the compatibility list on the Synology NAS and whether or not it works.

        Just Google “Synology_HDD_db”

        EDIT: In fact, they just released a guide an hour ago to even get the new Synology NAS’es to allow you to install DSM with unverified HDDs.
        REPLY ON YOUTUBE

      111. There are already scripts created that can add any disks to the Synology approved list or allow DSM to be installed on new disks. It remains to be seen if Synology will make changes to block them but for now, unverified disks can be used very easily.
        REPLY ON YOUTUBE

      113. There is no incompatibility with ‘unverified’ drives but aggravated obsession for customers money. Synology wants to make money out of thin air. Because most of Synology hardware was overpriced outdated trash 5 years ago and surprisingly it is now. But from now on company decided to do a quantum leap into degeneration and bankruptcy by enforcing usage of outdated and overpriced Toshiba drives relabeled. This would mostly hit home users, creators and some small businesses

        Whatever this company did it won’t revert the accumulated negative effect. So it’s time to say “bye-bye overpriced trash”!

      117. Curious if when a drive fails, if you can shutdown the DS925+, pull the good drive out, clone it to the replacement disk to get the synology partitions on it, place the original good drive back in and boot, then when running add in the cloned replacement disk to see if it will allow raid repair. Might have a similar situation as when replugging in the hot pulled disk.

      120. That is really a shame, hope they do add 3rd party to the compatibility list. Actually the Synology drives are not compatible in a lower version of DSM like 6.x while the 3rd party are, so overall they are the least compatible drives on the market! What concerns me also is if the Synology drives are compatible on other brand NAS’s ? So you can save your investment if you want to switch.

I want to transfer this pool to a new NAS. I’m hoping that I can move my current pool to a new DS1825+ then one by one replace my WD Reds with something like 16TB HAT3310s The cost will be prohibitive but I might be able to do this over an 18 month period… hopefully I will then be in a ‘safe’ position…

      130. I’ve been thinking about this verification nonsense from Synology, and it occurred to me that it is a brand lock-in, nothing more. Think about it, for years Synology have had NAS certified drives from Seagate, Toshiba and WD on their compatibility list, a list that they have claimed has been validated thoroughly. If this is so, and those drives from Seagate, WD and Toshiba have been fully verified for years, what’s changed? Why are those drives suddenly unverified now?

        How can drives previously on Sinology’s much vaunted compatibility list be unverified? It makes no sense to me. I believe Synology are appeasing their user base by saying third-party drives are/will be verified in future without seriously wanting to do this. This exercise is being done to evaluate user pushback. If most users shrug, grumble a bit and accept this new situation, Synology may quietly forget about verifying thirdparty drives. If, however, the reaction from the Synology community is comprehensively negative, they will miraculously include the third-party drives they’ve always had on their compatibility list in short order.
        REPLY ON YOUTUBE

      131. This is a huge showstopper for me and many. I have 918+ running and will most likely be looking for a way out of Synology ecosystem if they stay on this path. The hard part is replacing some of the apps that I use, like Photos (Immich?) and Drive (Nextcloud is the closest but bloated) and Surveillance station (???). If you are not using these apps then getting out of Synology should be pretty simple.
        REPLY ON YOUTUBE

      133. Synology going this route of trying to lock in their overpriced rebadged Toshiba hard drives is a Rubicon that cannot be uncrossed. The trust is gone. Even if they claim they will loosen the restrictions on non-approved drives, why should I trust they won’t simply reverse course in a few years? It’s time to move on from Synology.
        REPLY ON YOUTUBE

      134. I wonder if there would be market for hacking WD drives to identify themselves as valid verified drives 🙂 Most likely the firmware change they have made to the drives is very minimal and could be quite easily replicated/emulated on other drives.
        REPLY ON YOUTUBE

      137. That rebuild thing is a big problem, you should always be able to rebuild a RAID if drive fails, dataloss is worse than possible unstable behaviour that might occur. And if that really is a big issue, then just allow rebuild but keep the RAID in slow degraded mode where it really cannot be used until you rebuild it with verified drive, but in the mean time all the data will be safe as the RAID has been rebuilt and there is parity data.

The thought that I could never any of it, not one bit, in a brand new premium NAS just makes want to vomit. It kind of reminds me what what MSFT is doing with TPM and what Broadcom has done with VMware. Of course Apple does this same crap with their computers, phones and everything else. I have really high hopes for the new Minisform NAS and their OS. Really hope the Minisform NAS OS can be virtualized under Proxmox either on their new NAS hardware or the MS-A2.

It’s a real shame, I’ve loved the OS over the years, and I have boxes that have been powered on for something like 10 years non-stop. I have always recommended them as the go-to solution. Time to move on. Thank you for doing these tests, and for the great videos over the years. I look forward to finding out the best new options as they appear.

      152. Just say it outright: Synology can’t be recommended anymore. This policy is idiotic and most of the disabled features have absolutely nothing to do with drive “compatibility”.

      170. One of the most absurd thing about all this story is that the Synology drives I see listed on Amazon (at least here in Italy) are obviously either Seagate or HGST manufactured WD (that btw for some funny reason have the sticker flipped upside down compared to the OEM drives), so there is no reason for not allowing other drives of those brands to function inside the NAS.

      171. Good information. My opinion is to stay away from Synology for now. Even if you pay more and purchase all compatible drives today, it does not mean they will be on the list for your next replacement system. Sadly, as a home user, I like the SHR. Does any other manufacturer allow mixing drives.

      177. You could potentially try “initialize” the drive in the older nas to try to use it as replacement for degraded RAID.
        If you migrate the older box is usually kept as the backup so it may be kind of the workaround foe those who must upgrade.

      180. For a dominant NAS vendor like Synology, I can’t believe this product release was a marketing blunder. They’ve had plenty of time to verify 3rd party drives so the fact they have launched with a retricted compatibiity list speaks volumes for their mindset. Even if they add a few 3rd paty drives over the next few months, I think the writing is on the wall. Ultimately Synology will be a closed ecosystem and I’m certainly not going to validate their position with a purchase.
        REPLY ON YOUTUBE

      181. You do realize how Synology “works” with WD and Seagate. Just trying to squeeze money out of them for “verification”. Because their NAS disks are already absolutely compatible for the reason that no special compatibility is needed. They just need to meet industry standards.
        REPLY ON YOUTUBE

      184. I have a random crazy theory. I don’t know if it would work. Lets say you have four drives from an older system. You migrate them to a new NAS. They work! Now, one of those drives goes bad. You replace it with a new blank drive of the same model. The NAS rejects it. Just pull one of the working drives, put it in a system and do a sector by sector clone to the blank drive. The New NAS will recognize the new drive as being Synology and let you rebuild the system using it.

        At this stage, I’d consider it a risk to migrate a storage pool from an older model.

If you have a migrated pool & volume, you remove a “bad” drive, and you install a “new” unverified drive… that you first setup as a “blank” single drive in a DS923+ or whatever… would THAT allow you to use the single unverified to repair? Using an older NAS to “prep” drives to use in the DS925+ doesn’t make much sense, but if it works… well, that’s something. Again, thanks for all you do, and have a great day!!!

Outdated / limited hardware, removing features from software, and competitors catching up and surpassing them on the hardware side while options like TrueNAS, UNraid, and others are filling the gap on the software side without vendor lock in.

        The value proposition Synology once had been already trending down, with the new release it is gone.

      201. Really hope Synology watching your videos and reading comments. I wanted to upgrade to a 925+, and wanted to buy another unit for my parents house.
        Now i wont, and i will switch to ugreen or qnap.
        Hope you make a good amount on your rebranded drives synology.

      202. Synology is dead to me now. What folks should do — what I have done — is acquired a small Plus-series drive from the recent past that can run Active Backup for Business. Use that machine as an appliance for the sole purpose of network backup. Use larger devices from other vendors as the target of your backups and for all other purposes.

      203. All of this wouldn’t be an issue if Synology drives were readily available in the sizes in we want for a reasonable price, similar to the existing WD/Seagate offerings. But if I need to wait a week and pay anywhere between 10-50% more for essentially the same thing, then that’s what makes me extremely annoyed at this situation.

        IF you have a Synology system, maybe they should offer existing users a discount or something to buy Synology drives. They need to offer some incentive at least. However who knows how long that will last. Maybe a year down the road once we are locked into our 925+, they can decide at any point to significantly increase the price of the drives or stop selling certain sizes that meet our existing budget. Who knows.

        There are too many unknowns here and for that reason, it’s obvious we need to look elsewhere.

      205. If they planned the compatible list they would have at least some drives on it when announcing the units , they just wanted to wait if there would be a backlash. I skip synology for a while, will buy the unas and backup my old synology to that.

      206. I bought a Synology NAS last year. As long as they do not mess with being able to do the basics I will continue to use it until I need to upgrade. But, when I need to upgrade based upon what is being reported by nearly all, Synology will not be part of my next purchase. I think they have made it very clear that DIY is not their focus going forward. If the other manufactures go the same way there is always TruNAS.

      207. Dear Robbie, Thank you SOOOOO much. You’re the first to cover RAID FAILURE and REBUILD of Migrated systems [8:25 into your video: Test 8: RAID recovery fails with identical unverified HDD]. As soon as they announced they would allow MIGRATION, that INSTANTLY became the one CRITICAL QUESTION. You are the very first to answer. As a Mac and Synology consultant for 10+ years [and I PERSONALLY OWN 5 8 Bay Synology 18XX+ series servers]. This is the MOST IMPORTANT THING. And an ABSOLUTE DEAL BREAKER. Obviously NASs are about 2 things
        – PROTECTING your data from Drive Failure
        – Understanding that the drives in theses systems ABSOLUTELY [eventually] will fail
        – Allow ing you to RELACE Drives when they do fail.

        Since ALL my Synology servers [and ALL my clients] have AT LEAST 1 20 to 24 TB drive in EVERY unit they own, this is INFURIATING… and ABSOLUTELY UNACCEPTABLE. Either Synology has to:
        – STOP ALLOWING MIGRATION
        – Allow Migration and Replacement with UNVERIFIED DRIVE
        – SHIP reasonable price “PLUS” [NOT Enterprise] 18, 20 and 24 TB drives.

        They HAVE to comply with the above, I NEVER get mad, I’m a 1984 Mac Consultant who smiles and laughs all the time. I’m a professional poet & beer vlogger.. I do NOT get angry.. almost NEVER. I am ABSOLUTELY FURIOUS and this thing you have discovered of NOT ALLOW FOR a RAID to be REPAIRED when a drive fails.

        Thanks for discovering this.

      208. Well, if you’re a home user especially, why even try and deal with all the verified current and future compatibility issues that may come up? There are just too many other options available to keep jumping through the Synology hoops, and they are better and usually cheaper. For the home and small business user, look elsewhere, which is jus what Synology wants those users to do anyway.

      214. something important: the “unverified” status will override drives that have isues too, so if a disk is in critical status it will say “unverified” instead, very hard to actually know which drive it is, only indicator is the orange light, since the usual “disk critical” popup also didnt show for me.

      216. I am happy to say that late last year (having got fed up of waiting for a newer version) I purchased a DS1522+ and migrated the 6tb drives from my aging DS1415. No problem . I added a 16tb Ironwolf & then have since replaced 2 of the drives with 16tb Ironwolf, all no problem. Had I hung on for a 5 bay 2025 model I’d clearly be stuck with no choice but Synology drives. I’ve always used Ironwolf or Toshiba NAS srives and never had an issue.

      237. Be clear on the SSD storage pools, its not that other units do not support it, they do… Rather, this is just fleecing customers – Synology don’t want to enable on other models, as they want you to believe its “unique” to certain models an encourage you to buy the newer model, and throw the old one out (Yeah, great environmentally-friendly move there!

      251. I have a Synology DS918+, but the way I’ve always tried to use it is to basically make my setup idempotent as it were. What I mean is everything I host on there, I just host it with Docker using Docker Compose, so if I ever got another NAS, or built my own server – whether it was Unraid, TrueNAS Scale, or just plain Debian, I ought to be able to just install Docker on it, then copy my docker folder over to it (which contains the docker-compose.yml and all the persistent storage for my containers), then run: docker-compose up -d, and all my stuff should basically just work, without being dependent on a particular operating system or vendor.

        The only “first party” Synology things I use tend to be monitoring and backup. I do use Hyper Backup to backup my important stuff to Backblaze B2, but I’m wondering if Hyper Backup makes a backup that only a Synology NAS could read. If my NAS died would be be able to recover my data without buying another Synology NAS?

      259. I currently use a Mac computer with two Drobo 5D3 enclosures, which are generally relatively quiet. Each enclosure has five Seagate Ironwolf 12TB drives. The company is no longer in business so I need to replace them.

        I need a device that can handle five or six 3.5″ HDD drives and want something relatively quiet.

        I can hear the sound from the video. However, it isn’t easy to compare to what I have today with the Drobo 5D3.

        Would you have a comparison video or chart for the high-capacity enclosures on the market today, specifically with noise level comparison? Same question to which high-capacity HDD would generate the least noise level.

        I understand that the different drives will generate different noise levels, so I’m looking for the enclosure and how much noise it generates from the fan(s).

        Just think how many times intelligent beings got to our level, and do not exist anywhere on earth today, as earth is literally billions of years old.

        If humans stopped existing, just imagine how long it would take nature to get rid of all traces that we existed?

        Think about it.

        Just imagine for a second, how many times intelligent life could of come and gone before in literally billions of years of earths existence, and how many times nature wiped out the existence they had here. We have only existed as humans now on earth for about 10,000 years, which is nothing, in terms of billions of years, that earth has existed.

      266. I agree Synology doesn’t communicate properly to their customers why they are doing these decisions on their hardware/software. We may assume that they have done some study and statistics and they have found out that the majority of the videos their users store are 1080p anyways? Who knows…. With the hardware, I think they want to ensure that you have a consistent reliable experience and I know that not everybody’s RAM is made the same way and with the same quality. 1Gb ethernet bond is fast enough for streaming 4K. DS1522+ I have plays no problem 1080p to my 4K TV. (Let’s be honest I’m not storing 30GB movies in 4K). It plays no problem 4K video taken on iPhone to my 4K TV. Sharing photos but mainly 4K videos with family through Synology Photos across the world in 4K works, playing smooth. (Smooth to iPhones, PC, iMac, Androids struggle and you need transcoding)SMB works, backup of Apple and PC works and yes SSDs are expensive but why would you need them at home? These are not the Qnaps with specs that blow your mind, but I think they take the Apple approach. Overall I think is a solid package that will easily last me for another 10 years.

I have DS1522+ and have no problem playing Plex 4K and 1080p videos to my 4K TV, iPhone, iMac etc. Streaming 4K (taken on iPhone) across half of the world and watching it on PC is not problematic at all (on the standard out-of-the-box solution) as long you don’t have to transcode to some crappy phone that can’t handle the data. That’s when everything comes to a stop because as mentioned the CPU can’t do anything about transcoding. Synology Photos is ok but nowhere close to Google Photos….

      276. As I’m in the market, I’d be very grateful if you’d comment on the thoughts from another commenter who is much better informed at this granularity than I ????: “…CPU that cannot keep-up with its 10 GbE link in basic single-client sequential tests to its own cache. In real-world scenarios it is far too easy to tie-up this low-core CPU with other tasks, or small read/writes leaving it crippled for throughput. Even in your best case of around 800 MB/s throughput to cache, with little or no other concurrent tasks, it is incapable of filling its network pipe.
        To put that in context, look at the DS1517+ (yes, that old) with a CPU that was already considered both old and weak (Atom C2538 from 2013). It too could take a 10 GbE card – the regular non-propriety PCIe kind. Even without NVMe cache it could saturate a 10 GbE link on reads with 5 spinning HDDs of that era and run multi-client connections, mixed traffic, background tasks and VMs. Sometime more cores count, even with the terrible C2538. Fast-forward 9 years since the Atom C2538 and Synology launches its latest 5-bay Plus Series NAS with a dual-core CPU that cannot keep-up with the SATA drives it is hosting, gives you 4 x 1 GbE ports (in 2022!) as standard and asks for a considerable upgrade fee for a proprietary 10 GbE card that the CPU cannot keep-up with.
        This really isn’t a Plus Series unit. It’s a J-Series or, if feeling generous, a non-Plus unit with a proprietary NIC capability. If this model had shipped as the DS1522 (ie no +) with onboard 5 GbE or even 2.5 GbE we could cut Synology some slack – right now it deserves scorn and not hard cash.”

      315. Why synology is so poor in regards to the USB ports???…it’s disappointing…not to mention about 1GBE ethernet…Real bad connectivity…worst hardware upgrade ever…

      316. I am about to buy DS1821+. Do you think that its successor DS1823+ will come out later this year? Is it worth waiting a couple of months? I am not in hurry, but if I could get a great deal on DS1821+, I’ll take it anyways 🙂

      319. Synology would be best served to hire you as part of their development review before they release their devices in the wild. Woopee.. this can hit 32GB of ECC DRAM. I am still running my DS-918+ because that also runs on 32GB RAM, I have two 512GB M.2 SSD drives in the cache slots. I have four Seagate 8TB 7200 RPM drives, and the CPU has 4-Cores/4-Threads. Yeah, I’d love to have a newer CPU with more speed, cache memory, and built in GRAPHICS, but Synology isn’t listening. So I am not running out to by a new system from Synology and for once in my NAS journey, I am starting to look into other brands with 2.5Gb LAN ports and quite frankly better CPU specs.

      321. It looks like ds1621+ would be a much more solid option – it’s not that much more expensive, but it’s got better cpu and regular pcie slot as opposed to this proprietary contraption. I’m looking to upgrade my ancient ds1512+ which has served me well for what feels like eternity, but I was seriously hoping for 2.5G as my network is all 2.5G…

      325. Great job as usual. Thank you. I use Wi-Fi only so not concerned about 10Gbe Ethernet. What i am concerned about is the lack of integrated graphics and transcoding. Here in the US the DS 1520+ and DS 1522+ sell both for $700 at some locations. I am not sure if the 22 version is really a significant improvement for those who care about transcoding and do not have extensive surveillance camera system.

      326. I recently got a DS1520+ at a good price even though I knew this model was out. I wanted 5 bays and Plex hardware transcoding. Since it is for home use the potential file throughput performance, 10Gbe, and extra RAM is not that important vs. transcoding. I have UniFi system with NVR so I do not need surveillance support. No issues with HDD compatibility either. I am normally one to always want latest and greatest but not in this case.

      331. I actually prefer my DS1520+ with 20GB RAM (aftermarket RAM upgrade from Crucial) due to its ability to process and transcode video effectively via hardware. I honestly think a more powerful Ryzen CPU should have been used, or maybe a laptop based APU that has hardware acceleration. I’m worried this is a miss from Synology and have zero desire to upgrade.

      336. By the time you put 10GB Synology proprietary network card and Synology proprietary M.2 SSD, the cost of this NAS is already above 1250 EURs and I don’t even include here a proprietary memory upgrade, exactly just like apple, why these companies only copy the bad examples. Ok, good luck with that.

      337. Great video my friend. Still holding out a shred of hope that Synology will still release the 922+ this year :- Are you guys in the know, hearing anything to that end? Either way, keep up the good work fellas – love the channel!

      338. JUST made this video Live, so if you are only seeing 480p/720p, come back in 15mins when YouTube has finished processing the higher resolutions. Thanks for watching!
