Synology RS422+ NAS Review – Compact Power?

Synology RS422+ NAS Review – The Compact Ryzen Rackmount

Synology has really been hitting the enterprise and high-end business market hard of late! With the brand clearly making moves to try and occupy a place in the highest hybrid cloud and service level storage providers, some have been concerned with Synology’s continued commitment to the home, prosumer and SMB. Therefore, many users were relieved to see the release of a new 1U prosumer/SMB in the brand’s Rackstation series, the Synology RS422+ NAS. This new 4-Bay rackmount server changes familiar staples of this scale of solution from Synology that make comparisons between the RS422+ and the RS419 or RS820+ very difficult, as this system arrives with better base hardware than those two options, but also has a few upgrade and scalability hurdles that make it a pinch less future proof for some users. Indeed, the RS422+ rackstation is a notably different kind of Synology NAS. Let’s sink our teeth into this rather compact embedded Ryzen rackmount and see whether it deserves your data.

Synology RS422+ NAS Review – Quick Conclusion

What Synology has produced in the RS422+ Rackstation NAS is an intriguing middle ground between their more cost-effective ARM-based rackmount solutions and their more expensive scalable and upgradable servers. On the face of it, you are getting a tremendously compact but capable 1U 4-Bay rackmount server that, as soon as you factor in the included DSM software and services, is very good value for businesses that want to move their data out of 3rd party cloud and into something they have full control over. Additionally, that CPU (though a fraction divisive when compared previously vs Intel chips in the desktop DS1522+) makes more sense here in this more affordable Rackstation solution. The lack of NVMe M.2 SSD slots, fixed 2GB memory and lack off rails I am less keen on here (and I am still a little on the fence about the way they have pursued 10GbE upgrades in this system) but you are still getting a very well built and small scale NAS solution here and Synology have found a good price point here for this complete solution. Additionally, the fact that Synology has not been so restrictive on HDD use in this system than in more enterprise solutions in 2022 is welcoming too, though they are still taking an odd stance on some drives nonetheless. Ultimately, I can recommend the Synology RS422+ Rackstation NAS to smaller business users, though looking for a compact and very easy-to-deploy NAS solution for surveillance, central business storage, additional backup layers and for DSM as a whole. Though multimedia users might want to give it a miss.

Synology RS422+ NAS Review – Packaging

The first thing that struck me when I saw the Synology RS422+ NAS was how small the external box was. When you hear ‘rackmount’, your brain automatically thinks ‘big, awkward, noisy’. However, in the case of the RS422+, I was genuinely surprised at the scale of the box it arrived inside.

The unit arrives in the usual Synology packaging, 2 layers of cardboard and surrounded by hard foam for protection from shock damage and motion in transit. Synology has been increasing its range of more compact solutions in its portfolio for a number of years now (more commonly referred to as ‘half depth’), but still maintains the high level of protection that is afforded to them in transit. The unit is completely held in the rigid foam and the accessories pack, though a touch light on contents) in safely nestled inside.

Laying the contents of the RS422+ kit out on the desk shows that there is not a tremendous amount of contents to feast our eyes on. There is the NAS, screws for 2.5″/3.5″ media, details on the 3yr warranty, ethernet cables, first-time setup instructions, optional system handles and a mains power cable.

Although I am still a little surprised that Synology never include rail kits with their rackmounts by default (which might be a bit of a time/ease-of-access advantage if you use this in a full-depth rack cabinet that has standard depth rackmounts already installed alongside it), they do include the optional handles that allow you to slide the RS422+ in and out. Though I can definitely see alot of users considering installing this system outside of a classical rack cabinet setting, thanks to it’s small scale chassis. So perhaps in the case of half-depth rackmounts (especially in 1U) making rail kits options makes a little more sense.

The ethernet cable included with the system is Cat 5e, which given that this system is 1GbE by default is perfectly fine. Overall this is a fairly standard and safe accessory kit that will give you pretty much everything (aside from media, obviously) that you will need to get this system up and running quickly. The protection and presentation of the system is as AAA+ as always from Synology and their high-class branding/image continues to set it apart from box shifters. However, it’s what is on the inside that counts! Let’s discuss the design of the Synology RS422+ Rackstation NAS.

Synology RS422+ NAS Review – Design

This 1U Rackmount chassis features 4 bays of storage on the front, as well as an additional ventilation cavity above the HDD bays. Rackmount devices will almost always use a more horizontal means of internal ventilation, allowing air to pass through the system in this controlled, single-path fashion. The complete chassis is metal, with a plastic front panel.

Each of the bays can support a 3.5″/2.5″ drive, connecting to an internal combined SATA+Power connector. Though this system does not feature M.2 NVMe SSD bays internally, you can still occupy one or more of the main bays with SSDs and still use this feature. However, with only 4 bays available and no support of expansions (RX418), it would be a little fruitless. The RS422+ also supports Synology’s flexible RAID system, Synology Hybrid RAID (SHR), so mixing drive capacities is an option on day 1 or day 1000 increasing storage gradually if needed. There is also the support of traditional and more rigid RAID types, such as RAID 1, 5 and 6, so it’s good to have the choice.

It is worth remembering though that Synology has been a tad more selective about the HDDs and SSDs that they have put on the RS422+’s compatibility than in previous releases in this series. They are not as strict as those of the 22 XS+ series or high capacity solutions that only seemingly support Synology storage media, but there are omissions such as WD Red and Red Pro drives that will lead to many querying their absence. These drives will likely work, but DSM 7.1 will likely highlight that they are not on the compatibility list and recommend their replacement (with an amber alert notification present).

The trays inside the RS422+ NAS are metal, lockable (with keys included in the accessories kit) and have screw holes for installing media very easily. This system also supports hot-swapping (i.e. removing/adding drives whilst the system is on, though never remove a drive from an existing RAID pool), Hot spares (initialized drives that sit and wait for use in RAID re-builds) and Storage Manager in DSM also has the support of a FAST RAID Rebuild option. This is a feature that, in the event of a drive failure, the RAID rebuild will only rebuild the data on the areas of the disk where it was before (as opposed to checking and verifying even the empty spaces bit by bit) and the areas that had no data are simply zero’d out.

The front of the RS422+ lacks any LCD panel and instead features multiple LEDs that denote the system activity (network health, drive access, system status, etc). For such a small profile rackmount ANS, this will be more than sufficient to get an idea of how the system is operating at a glance. The RS422+ lacks any KVM access or direct interface without a 3rd party client device, but this has always been how Synology have designed their systems on the whole.

One thing that is very unique to rackmount NAS from Synology that you NEVER find on any desktop system is the inclusion of a mute button. Now, this button is designed for when the system starts beeping to alert the end-user/on-site-techie that something is amiss. These alerts can be customized to cover everything from serious stuff such as a RAID drive failure, network disconnection, system resource overuse or substantial rise in temperature. However, perhaps because of the enterprise and/or rackmount nature of the device, these rackmount systems feature an extra option to switch off these audio alerts. I have never quite understood this, as rackmount servers are all too often in a dedicated area of a building (server room, cabinet, cupboard home lab) because they tend to make more noise in operation 24×7. Whereas desktop NAS servers are all too often in the same room as people working. So, both in terms of proximity to the noise and convenience of quickly disabling the noise without entering via a browser/app GUI, it would make so, SO much more sense to have them on a desktop. Still, nice to have it here, I have just always wondered about that.

As mentioned earlier, you can attach handles to the front of the RS422+ to allow for easier removal from a rack cabinet for maintenance. It would have been nice for Synology to include rails with the server, but ah well. Attachment of the handles takes barely a couple of minutes and they feel nice and sturdy.

Overall, the design of the Synology RS422+ is of an expected high quality. There has been little or no change in this chassis compared with the older gen 1U rackmounts, but that is not a bad thing – if it’s ain’t broke, don’t fix it etc. The choices by Synology with regard to storage media are a little less transparent than some might like, but at least there is a wider degree of storage media supported on this system than many of the higher-end business products in the 2022 releases so far. Let’s discuss the connectivity of the Synology RS422+ Rackstation NAS, as we have an interesting mix of stuff to cover.

Synology RS422+ NAS Review – Ports and Connections

Rackmount servers have always been among the most desirable when it comes to business, largely down to generally higher hardware inside, greater network connectivity and increased expandability (unsurprisingly, given modern businesses are the ones producing the most data). Now Synology is no stranger to this, even in 1U rackmount form, but in spite of this the RS422+ is possibly one of the least scalable and upgradable rackmount solutions that the brand has ever introduced into the plus tier of it’s rackstation series. That isn’t to say that the RS422+ doesn’t;t have some solid hardware inside and out, it is just noticeable more ‘lower glass ceiling’ than almost all of their current rackstation solutions in 2020/2021/2022. The available connections on the rear of the system are (for the most part) exactly what you would expect, comparable to most other rackstation solutions.

Unlike some of the bigger/scalable solutions, the RS422+ does not feature a redundant PSU option (i.e. an RP version, such as the RS822+RP+ or RS2422RP+), though it DOES support Synology High Availability (SHA) to sync two RS422+ NAS’ together in an Active/Passive failover dynamic. What it has in its petite rack chassis is a single modest 100W internal PSU that Synology reports (when fully populated with HAT5300-16T HDDs) power usage of 37.93 W (in access) 13.43 W (when in standby/hibernation). That is an impressively low power consumption for this 4 Bay, especially when you factor in that AMD embedded Ryzen 64bit x86 processor. What about noise?

Well, that’s another of the classic rackmount associations that the RS422+ manages to counter – it’s actually quite a quiet rackmount NAS. Obviously, it is noisier than a 4-bay desktop equivalent (having metal trays, a metal chassis and technically three fans doesn’t help) but with Synology measuring the system at 28.5 dB(A) when in full population with Synology media and in active use, that is a fraction of other rackmounts out there. Alot of that comes down to the petite design, 1U height and single PSU frame. But regardless, that is a surprisingly quiet rackmount.

Now one of the latest additions that Synology have been making to its 2022 generation of NAS solutions is in the subject of 10GbE upgrades. Network upgrades in Synology NAS systems (including many desktop NAS systems) have always been on offer on many of the PLUS series devices, however in the case of a few (including the RS422+) the way this is made available has changed. The Synology RS422+ features a small, square upgrade card slot on the rear of the chassis that is specifically marked as the Network Expansion Port.

Although architecturally this is similar to a PCIe slot, there are a few very important differences. The first is that you can no longer use standard 10GbE upgrade cards that arrive in full/half-height PCIe here. In order to attached 10GbE to the RS422+, you will need to use the new E10G22-T1-mini adapter module. This is a new, quite proprietary upgrade unit that slots into this available network expansion slot of the RS422+ that, although much less invasive to install and easier to maintain, is a very brand specific piece of kit and not something that you can buy from a third-party vendor. Now, this isn’t a huge surprise. Synology has been increasingly focusing on first-party accessories and components for their hardware for a whilst now (HDDs, Memory, SSD Cache, etc) so another move into the one-ecosystem/all-in-one solution-provider area by the brand is not going to surprise too many. However, Synology already has a range of very, very good PCIe cards to upgrade towards 10GbE, 25GbE and even combo cards that are all very good. I think it would have assumed that a traditional PCIe slot on the RS422+ would not have been especially hard (looks at the other 1U rackmounts – even those with Atom processors in the past). Equally, as this new 10GbE adapter is very new, prices are quite irregular right now and in many places the new designed 10GbE adapter is more expensive than the current PCIe E1018-T1 card.

The new 10GbE adapter card is PCIe Gen 3 x2, whereas the older generation PCIe card is PCIe Gen 3 x4 which, although might sound like the older card is better, means very little as the card is still a 10Gb card and both of these PCIe speeds/gens will give way more bandwidth than these cards can possibly saturate. The slot inside the RS422+ is also a PCIe Gen 3 x2 slot too. Not to labour the point more, but where is the SFP+ option too? This card arriving for rackmount, at least in my eyes, would certainly see a decent % of users wanting this is fiber for those longer distances and larger scale building installations. Perhaps the E10G22-T1-Mini is the first step towards an E10G22-F1-mini or E10G23-F1-mini? We shall have to wait and see.

What about the default network bandwidth of the Synology RS422+ NAS? Well as you might have suspected, it is another release from the brand to feature 1GbE network ports. Now, one might argue that this is the CHOICE to add 10GbE via the previously mentioned slot if increased performance is needed. Additionally, some might argue that the current trend for 2.5GbE in NAS is not essential, given that 1GbE and 10GbE are the more widely adopted client hardware connections. Those are both good points with a degree of merit. However, two 1GbE network ports here (so 109MB/s, or around 220MB/s or so via link aggregation) are going to immediately be a bottleneck for those 4 drive bays (HDD or SSDs). Additionally, 2.5GbE is fast arriving at the same/similar cost to 1GbE on client hardware (switches, routers, adapters via USB costing as little as $20) and although 2.5GbE has lower integration now, who’s to say where it will be in a few years and for users who are investing in a NAS with future-proofing in mind, 2.5GbE would likely have been appreciated. Perhaps Synology can make a case of PCI lanes on the CPU being stretched thinner – but with a reduced network upgrade slot of PCIe 3×2 (previous devices have 3×4 or 3×8) and 2 LAN ports, not 4 as seen previously, this does seem like an odd move.

The last ports present here are a USB Port and a COMs port. The COMs port we can largely ignore (those that need it will already know about its use and connection to existing systems in-house), but the USB port here is another puzzler. For a start, there is only x1. Even if you only factor in that Synology provides these for UPS devices and external storage (many other compatible devices such as printers, scanners and network upgrade adapters have had support discontinued or unverified officially), that still means that there is only one port to do this. Given the lack of a redundant PSU, most businesses will use this for a modest UPS – a 24×7 connection, so USB storage is off the table. Another example of this system appearing a little streamlined in comparison to many other rackstations.

Then there is the subject of expandability – of which the RS422+ supports zero. Unlike the recently revealed RS822+RS822+RP+, the RS422+ does not have an eSATA/External-SAS connection for an expansion bay. On day one, that’s ok. But years down the line, even the support of SHR is not going to be particularly useful in this 4-bay system when needing additional storage for existing volumes and shares. That’s a shame, as the 10GbE expandability would have paired well done the line with increased storage as your data grows.

The ports and connections of the Synology RS422+ are ok. The inclusion of a 10GbE option is nice, but already something featured in 1U Plus series rackstations before – and in a less proprietary form. The 1GbE ports are a tad underwhelming, but there is always the case that users who do not think 1/2GbE is enough will immediately jump to 10GbE anyway. Let’s dig a little deeper and see what the inside of the Synology RS422+ has for us.

Synology RS422+ NAS Review – Internal Hardware

The chassis of the Synology RS422+ Rackstation NAS has an accessibility panel on the top of the chassis that allows access to the internals of the system. However, the RS422+ does not really have any internal upgrade options, so the main reason that you may need to access the system internals will be for cleaning/light maintenance. It is held in place by 5 screws and slides off very easily, exposing the internal board and the storage bays (which take up a good 60% of that space).

There is a tonne of space and ventilation throughout and the PSU is not a closed unit either, but a bare PSU to allow 1) a more compact and convenient arrangement internally and 2) further cooling/ventilation. The arrange meant of components across the main controller board is very clean and you can clearly see the key components have been sensibly spaced out too. The small flash module that contains the default DSM installation package is tucked in at the corner and the system arrived with DSM 7.0.1 by default. It is worth remembering that DSM, when installed, lives on the core storage drive media/RAID and this flash module is for first-time setup, as well as getting updated with the latest version of DSM (for future reinitialization) during setup.

The 2GB of DDR4 memory that this NAS arrives with arrives soldered to the main controller board, as opposed to arriving in an accessible/changeable SODIMM upgrade slots. This is going to divide opinion a little and how this gets judged comes down a little to how this device is going to be marketed. As a value/cost-effective system, fixed memory is quite standard and allows easier and more affordable production, as well as allows the brand to flesh their portfolio out towards a buyers spending/budget-priorities alot better. If this is a prosumer and/or mainline SMB system – then having this memory locking in at 2GB is a little less positive. The memory comprises 4x DDR4 512GB modules and an additional module that is the ECC component of this memory – something many database and file management NAS buyers are going to appreciate!

It’s definitely a bonus that the RS422+ NAS is yet another solution from Synology that features error-correcting code (ECC) memory, which is certainly a high-end business preference for many. This type of memory benefits from an additional module on board that checks data as it enters and exits the RAM and if inconsistencies or errors occur during the write, this memory recognizes this when comparing the format of the binary at the beginning and end of its pass through, restoring the data to its integrity before it is committed to the larger NAS system during a write operation. Those that utilize larger databases or simply huge amounts of data that are high in frequency but low in volume. Will certainly see the benefit in this rather than encountering corrupted data days, weeks, months or even years down the line. This is by far the smallest rackmount/rackstation NAS that Synology has released to feature this more enterprise-grade memory.

Now, let’s get it out the way immediately. For a four-bay NAS device running DSM7 and with an optional 10GbE connection – the Ryzen R1600 is a good CPU. Its two-core, four-thread architecture, though a little weaker than many would have hoped, has an excellent power vs efficiency level and when combined with the support of ECC memory enables the system to get more done reliably and also whilst utilizing less raw power. Other desktop and rackmount NAS from Synology that feature a similar quad-core Ryzen (the V1500) proved that this processor is more than up to the task of managing multiple RAID pools and volumes whilst in 24/7 server use. Equally, no doubt Synology have benefited from lessons learned in the previous embedded Ryzen NAS developments that have resulted in this new R1600-equipped system benefiting in how well it runs DSM7 applications. Although industry measurements are a little few and far between on this relatively new processor, the hardware architecture behind it stands out very well.

The issue for many thought, as mentioned earlier in the review and in my DS1522+ NAS review, is going to be that this is NOT an embedded graphics processor and many users look at this scale of solution as a mixed-use device for home and business, or just for purely enjoying multimedia, are going to be a bit underwhelmed as that is something that this processor is less suited for. The hardware architecture we have here is going to result in very high CPU utilization for even mid to low-end multimedia handling and heavier tasks such as 4K multimedia and transcoding while streaming, are going to push this process to the 100% utilization mark very quickly. Many are concerned that Synology may be in the process of reshaping the lower tiers of their portfolio to solely utilize these Ryzen processors, something I assume and indeed hope not to be the case. Additionally, it is worth highlighting that this particular family of Ryzen CPUs (The R1000 series) does feature AMD Vega embedded graphics options, so it is an odd choice by the brand to stick with this product family but opt away from more graphically proficient processors that are in the line-up.

Now, it is ALSO worth noting that Synology has very, VERY rarely featured an embedded graphics chip in their rackstation series and in this tier of their portfolio (i.e between ARM 32/64bit processors and expandable Atom/v1500B equipped rackmounts) the R1600 processor IS a step up! The Sequential performance with four Synology HDDs in a RAID setup via the 10GbE adapter was rated by Synology at 601MB/s Read over 516MB/s Write – which does sound low for a 10GbE connection, but you have to factor in that these are HDDs and a pure SSD setup in the write RAID could likely fully saturate the 1,000MBs connection. We were able to hit this with Seagate Ironwolf SSDs, but did not have Synology SAT5200/SAT5210’s on hand to test with the first party media.

The hardware inside the Synology RS422+ is not certainly very deliberately designed to provide a solid base of resources to run DSM/3rd party services whilst still maintaining a god price point, but also resulting in a much lower glass ceiling in terms of future-proofing and scalability of the system. Having a 10GbE upgrade is always welcome, especially at this price/storage tier, but the lack of an expansion option, lack of option to upgrade that memory above the default 2GB and lack of M.2 NVMe SSD slots to take advantage of caching (despite the £650/750 DS1522+ NAS featuring them + 8/32GB Memory, 1 more bay + 1 more USB, but the same R1600 CPU) is going to quite a hurdle for those who want to provision for the future of their storage system.  Let’s discuss the Software that is included with the RS422+ Rackstation NAS, as DSM 7 is still very much the jewel in the crown of Synology’s NAS solutions in 2022, 2023 and beyond.

Synology RS422+ NAS Review – Software and Services

Now, to cover the WHOLE Synology software and services that are included with the RS422+ NAS would result in a review that is twice as long as this review so far! Synology’s Diskstation Manager software that comes with this device (either DSM 7 or DSM 6.2 depending on your preference) provides a massive arrangement of services, applications (first and third party supported) and a huge number of client applications for desktop, mobile, windows, mac and Linux (as well as a bunch of other more home-based tools). These allow management and access to the data on the RS422+ in very tailored ways, as well as the web browser-based access that has the appearance, intuitive design and responsiveness of a local operating system. The DSM interface can be accessed by hundreds of users at the same time (with each user having tailored access, rights and privileges). DSM is available with ALL Synology NAS and the depth and abilities of DSM on any NAS are dependent on the hardware architecture of the NAS itself. In the case of the Synology RS422+, it supports practically EVERYTHING (with the exception of SHR, as previously mentioned). If you want to learn about the latest version of DSM 7 and the software and services that are included with the RS422+ NAS, watch my FULL review below (alternatively, you can read the DSM 7 Full Review HERE):

As mentioned, the RS422+ supports pretty much the entirety of the DSM 7 and DSM 6.2 applications and services. If you are an existing user of SaaS and PaaS (Software as a service and Platform as a service) from the likes of Google Workspace and Office 365, knowing that you can synchronize these systems or choose to export away from them onto the Synology services is going to be very appealing. Key business applications that are included with your NAS are:

You cannot really fault the software and services that are included with the Synology RS422+ NAS, as you are going to get the very best experience available on the platform, thanks to the hardware and architecture of this NAS. DSM 7 is an every evolving platform, so if you are reading this now at the time of publishing or years later, there is always going to be something in DSM for everyone.

Synology RS422+ NAS Review – Conclusion & Verdict

What Synology has produced in the RS422+ Rackstation NAS is an intriguing middle ground between their more cost-effective ARM-based rackmount solutions and their more expensive scalable and upgradable servers. On the face of it, you are getting a tremendously compact but capable 1U 4-Bay rackmount server that, as soon as you factor in the included DSM software and services, is very good value for businesses that want to move their data out of 3rd party cloud and into something they have full control over. Additionally, that CPU (though a fraction divisive when compared previously vs Intel chips in the desktop DS1522+) makes more sense here in this more affordable Rackstation solution. The lack of NVMe M.2 SSD slots, fixed 2GB memory and lack off rails I am less keen on here (and I am still a little on the fence about the way they have pursued 10GbE upgrades in this system) but you are still getting a very well built and small scale NAS solution here and Synology have found a good price point here for this complete solution. Additionally, the fact that Synology has not been so restrictive on HDD use in this system than in more enterprise solutions in 2022 is welcoming too, though they are still taking an odd stance on some drives nonetheless. Ultimately, I can recommend the Synology RS422+ Rackstation NAS to smaller business users, though looking for a compact and very easy-to-deploy NAS solution for surveillance, central business storage, additional backup layers and for DSM as a whole. Though multimedia users might want to give it a miss.

    1. I’m the one who watched the whole thing! And some bits twice. Very helpful in trying to decide between a Synology DS923+ and Qnap TS464. Synology seems to have the upper hand software-wise which I suspect carries more weight for a home user than the superior hardware of the Qnap? Thank you for providing this extensive review!

    2. Awsome information. Now please a similar video on Qnap. I cant make up my mind as I need both photo management and video surveillance. It seems like Qnap and Synology takes 1 point each.

    3. Jellyfin?!!! Most channels that review media server software, either only deep-dive their preferred offering, or only give an overview compression of the field. If someone like you, who can give the same enthusiasm creating two videos deep-diving two NASs that only differ by a drive bay, puts that into a spin-off series on a topic that is close to a large chunk of your demographic, that would be a real treat.

    4. Thks & I just watched it again & most excellent;
      I’m a retired physicist & have no real problem understanding the infinite details.
      However my problem is how to keep it simple & stupid (ex: high tier levels of simplicity, brevity, encapsulation, etc).
      Oh with my goal is to sociably knit-together all my family, relatives, friends, etc on my synology NAS.
      Unfortunately I’m going to be Mr Tech support for them. Sooooo I gots-tos keep-it-simple is an understatement & I will be abused (I says anything for family/friends though ;).

    6. Thanks for a great video. Really explains what everything is. Recently got my NAS and been already updating hard drives in it. It will mainly be used as a PLEX Server but already considering what i will do when i start upgrading the smaller drives in it. May consider another NAS and use it as strict data back up and maybe a synology Drive / synology Calendar and Email setup. Move my calendar off Google’s stuff. We will see If i do that at some point. Great job again

    7. My English man!!! What a video! Greetings from Greece! I really appreciate your hard work and that content. I have a DS 1520 + and I am not regretting getting it although the new 1522 is out. You have my admiration. Keep up the professional and good work.

    8. *Note* – Regarding picture quality, this is a BIG video (so many features to cover in a single video) and YouTue can sometimes be a little slow to process HD and 4K uploads, so if this video is in low-quality for you, maybe come back in an hour or so, as YouTube should have finished processing it and have the 4K, 1080p and 720p versions done. Thanks for watching and hope you enjoy the review of Synology DSM 7.1, featuring the DS923+ NAS.

    9. Can you install VMM on RS422+? On Synology web is this option missing… But for my user case it would be perfect solution instead of buying quite expensive 822+/1221+

    10. Hi I got the Synology RS411 and I don’t have any HDD for now and I can’t get connection. Do I need to have a HDD at least? How do I install the SO? What I must do? ahah thaanks
      REPLY ON YOUTUBE

    11. should have cost half, rails included, 10Gbe included,
      at this price point Synology shot themselves in the knee,
      I understand homelabs and smbs may want networked drive bays without anything extra, which arguably this unit aims for, but once you add proper server next to it, this should be priced like 4-bay USB-C/Thunderbolt enclosure at best….

    12. Hard disk compatibility is short, just Synology and some IronWolf/seagate and Toshiba,, so if I going to use my old WD i will get the warning about the disk ?..
      REPLY ON YOUTUBE

    13. There’s a lot of variability in rack depth so kind of understand them not supplying massive 600mm sliding rails to everyone but some extending side supporting shelves would be good.
      Would the 16TB limit be related to the current (Toshiba MG) Synology branded drives maximum size?
      Would be nice to have more USB, 2.5g, and ESATA to handle a port multiplier and storage expansion.
      Not sure 10g really needed with hard drive storage.

    14. Why aren’t the Ethernet ports in the front? In a rack,… patch panels in the front…. so I have to slide it out and route behind? C’mon.

      I’m looking for a replacement for my DS 716
      The short rack is interesting for me but only 2 GB is not enough
      Still hoping for a 722+
      REPLY ON YOUTUBE

    16. Who is even the target audience of this? It’s a rack mount, which indicates enterprise or at least SOHO/SMB. But then you look at the CPU, which is woefully underpowered as well as the laughable 2 GB RAM NON-upgradable, which wouldn’t even satisfy anything but the very basic home users. Add to that the HDD compatibility list which do list NAS drives, but no pro or enterprise ones barring Synology branded models which they will ofc always try to push. And then ofc the 1G NICs. I mean does this even know what it wants to be?
      No Rob, you’re not being negative. You’re rightly questioning Synology for another pointless product, in your own very polite way even though they don’t deserve it. Good on you ????

    17. This is not a well-equipped storage solution. This is a minimal black box (siler actually) that needs media to do anything. This lacks CPU power, memory, only 8 PCI lanes, no GPU, no caching benefit, and still $699 bucks.
      REPLY ON YOUTUBE

    18. Sliding rails would be useful if there was a top cover you could take off, like on servers. The non-sliding ones are useful if you need to distribute a heavier load across four posts of the rack. I don’t see a dire need for either in this case.
      REPLY ON YOUTUBE

    19. In terms of the mute, the idea of it is not for you to walk over into the datacenter to mute the beeping. It’s there to provide the ability to silence the alarm to those working near the beeping device and to acknowledge the fault. This is especially useful if you’re addressing something unrelated/more pressing at the moment and will only look at the issue with the NAS at a later time.
      REPLY ON YOUTUBE

    20. The mute button make sense, if u have a more stations (20) in a rack and all have a problem, you need to work in this room. You have newer 20 desktop disk stations in one room, or?
      REPLY ON YOUTUBE

    21. I wish rails were included for the short-depth NASes but even Synology do not make rails for their short-depth series. You can of course fit their full-depth rails but for that to work you have to have a deeper rack. Where these NASes are most useful is in the SMB and Prosumer space where short depth racks or even comms cabinets are common; so long rails are impossible to fit. There are lots of racks out there where hanging from the front is either awkward or just beyond the strength of the front uprights – bending and sagging is not a good look.
      Anyway, poor connectivity, poor CPU, no graphics, no upgradable RAM does indeed = J-series but this is badged and priced as a Plus Series. It is a bad deal.
      REPLY ON YOUTUBE

    22. I don’t use rails and I don’t see why you would need them for such a shallow chassis. I’m glad they don’t include them so I don’t feel like overpaying for stuff I don’t need. I do like the new 10GbE card, much easier to install. But proprietary usually ends up being expensive. The onboard 1GbE should’ve been 2x 2.5GbE though. Now it’s almost mandatory to buy the networkcard.

    23. I cannot beleive that there is NO WAY to sync any folder and file type from android device to synology nas… that drives me nuts… it’s either super complicated third party app to configure or the only syncing possible is with ds file that does ONLY pictures or synology photo crap app… I just want to sync ANY folder and their files in it (like download, ringtones and so on)… why the hell can’t synology do such thing ??? ds cloud does NOT permit to sync android folder to nas, it only sync the cloud that is on the nas to the android device, I want the other way around, there is no way to sync android ANY type of android files to nas.. urgh…
      REPLY ON YOUTUBE

    24. My synology is messing up my local network and I can’t figure out why. Internet drops for a few seconds every few min on all connected network devices. If I disconnect the NAS from the network, it seems to work just fine.

    25. Login Speed – seemed easier with entering user name and password on the same dialogue to only hit enter once, especially when credentials are stored in the browser. Perhaps they changed it for increased security, prefer the old way.

    26. 8:40 – I wish we could find the person responsible for using a Funnel for the filter icon and make them walk the plank. Funnels are not filters.
      But its too late now. The damage is done. People associate the funnel image with the filter action in software just like they associate the piece of paper with a folded corner for “new file”.

    27. The missing “For you” from moments sorely missed – it was a great AI system for finding potential duplicate (or near duplicate) photos that just doesn’t work as well as the storage manager reports that only really find exact duplicate pictures.

    28. 1.Log center cant be modified or set to exclude users or certain things you dont want logged.

      2.It is not compatible with DScloud anymore so you cant sync to mobile like you can do on DSM6 with the DSCloud app from Synology but you can use the Synology Package Center to download Resilio Sync or Good Sync but you have to pay a monthly/yearly fee for every user.

      Unlike Qnap when you buy your hardware, you arent forced to pay for syncing from and to your own hardware.

      With that said there is still a solution using Webdav to-way Nas-pc with Raidrive but you have to pay for software for Pro features.

      Mobile sync: Use Foldersync to-way Mobile-Nas, but you have to pay for software for Pro features.

      So far as i am aware of limitations using Synology DSM7 when it comes to syncing —> If you want Pro features or you want to use your Nas without reaching out to third-part software without paying extra fees it is recommended to switch to other Nas brands for me i feel Qnap has been working using 30 users for Laptop/Pc/Mac/Android/Iphone all Apps/Software working perfect Pro features without paying extra fee´s or forced to use third-part tools total control for Log center, File-Folder, Photo, Video, Virtualization, Web-sites and so much more.

      Other annoying difference i had with Synology i had was this—> i had to make a ticket to find out i cant use Synology Mobile App DS Cloud or that one cant choose what Synology Package-Log Center loggs, it wont let you choose to include, exclude or to delete certain logg if you press Clear button on the loggs that are in “Files downloaded” it deletes all, if you clear “user logins” it deletes all that and you cant revert the deletion.

    29. Totally agree with your view on Photo Station. I’m glad you covered this as your feedback might get recognised. I don’t want to upgrade until Photos is comparable to what Photo Station had/has to offer.

    30. almost perfection?
      Audio Station is totally broken, playback is being cut off,
      Media indexing fails to scan more than 50% files,
      translations in DSM are not complete, some even have nonsense,
      I have no idea what Synology have been doing all the time releasing such buggy software

    32. I’ve installed it as a VM on my DS1821+ and I’m completely disappointed with the new photos app. Maybe I’m old fashioned idk but the way timeline view is implemented it doesn’t allow you to look at a timeline on an album level anymore like you could do in photostation. You have to choose between album view or timeline view. I like to look at my photos different ways and this makes the app kind of unusable for me. Additionally I would like them to shows tags on the timeline view when you’re inside an album that has multiple albums underneath it but no photos in it directly. I’ve reached out to them but very little hope of it getting done in my opinion. I’m not upgrading until photos is useable as photostation is no longer supported on dsm7. Additionally I had a lot of indexing / conversion issues on my VM with my photos directory. Not sure if that’s just a VM issue or not

    33. Hi. Is it safe and or good for my Synology 920+ to be shut down during the night and sometimes for 30 days at a time while away? Many thanks for your great videos.

    34. I upgraded both my DS 218J and my brand new DS920+ to DSM 7.0 and liking it a lot! No real problems. Moments with my Photos lost its tags during the transition to Synology Photos. I have to redo them but that’s ok. Everything else is great. I agree with this review.
      REPLY ON YOUTUBE

    35. so is there any reason for me to wait for the DSM update to come through automatically on my DS1520+ or should I just manually update now? Is it likely that more changes will be made to it before the automatic update comes through?
      REPLY ON YOUTUBE

    36. Does DSM 7 introduce any issues with access via the NFS protocol? I use my DS420j strictly as a file server in a Linux environment and do not really care about photo station, music station, etc. Quick, reliable access via NFS is my main concern. Thank you for your fine videos.

    37. Photos all seemed to work once I requested a re-indexing. However, photo sharing is completely broken. Even if you request that anyone can view with a URL, Synology NAS still requests a username and password. Sigh…………………

    38. I notice the absence of Amazon S3 on the cloud service for HyperBackup… Is it still possible to backup to Amazon S3 Glacier storage in DSM7? Or they removed it not to compete with their own C2 solution?
      REPLY ON YOUTUBE

    39. Thanks for your valuable videos. I missed the loss of DS Cloud, so syncing became a problem. I started using Syncthing after upgrading to DSM7. I also have a problem with Synology Drive from my laptop on a company network, while using Express VPN. It keeps trying to connect to the server. When I switch off the VPN it works fine. Maybe I will switch to Syncthing on this Windows machine as well. For me this is a key function for a NAS so I didn’t expect it to work less good. But all and all it’s a big improvement.

    40. No mention of the issues with third party packages that worked fine in 6.2.4 but no longer work in DSM 7, it might be almost perfect IF you only use Synology apps.

    41. Hello, I am sure that it will surely be for reasons of not extending the video too much, but your way of showing and explaining the news and characteristics of this new DSN are not very clear, at least for me you are going too fast and a bit messy. I’m not saying it in a bad way but I think you could do it in a more calm and neat way. Thank you very much anyway.

    42. I use a KDLinks media stream box to watch movies and videos I store on my Synology NAS DS918+. Does DSM 7.0 support the ability for the stream box to sign into the NAS and stream the files?

    43. 20:53 I ran into the exact issue you have 2 days ago on DSM6.2.4. I opened a support ticket that is still open, however I suspect it’s a browser based issue. Try opening in a different browser and see if you can view all of the back up options in that. It’s a Munster to me how this happened as I even cleared my browser cache and it persisted in Firefox. When I opened in safari it was “fixed}

    46. One thing I’d love is for larger NAS to support mounting volume from older smaller NAS.
      For instance, I had an old DS411j that failed on me, one of the drive failed but the NAS was full, so now I can’t even start it up. I just wish I could buy some of the 12 slots new NAS and then mount my 4 old drive into the new system and then just transfer data and format the old drives to add them to the new volume. I asked Synology if we can do that, their answer: nope, unless you build a Linux computer and mount drives on Linux and transfer your data. If I need to build a Linux computer, I’d better off just to use FreeNAS and never have to deal with Synology DSM…

    47. Microsoft Edge is base on Chromium, so any issues you have with Chrome will most likely happen in Edge as well. You need to test on browses like Firefox that are not base on Chromium.

      I use Firefox and only have one M.2 slot filled and the 4 HDDs bays are full. Testing what I could zooming out made the empty M.2 disappear. It did not make the icon show under the other one as shown by you..

    49. For the past week, Universal Search has been HOARDING CPU and RAM!
      Indexing just goes on and on and on, non stop!

      I can’t find a workaround!
      Disabling Universal Search in DSM 7, disables Synology Drive and Synology Office

    50. For me it doesn’t matter as much if the new apps arent quite as good as the old ones yet as long as they have been written on a newer platform that easier to add missing and new features later rather than an app that was based on ds 4. Apple’s old website went down before a launch not to increase excitement but because it was old and rubbish and had to be .

    51. Still I have hibernation issue and I opened a ticket with Synology support. After analyzing the debug logs, they came back with SMB and VMM are the cause of periodic waking up of HDD’s. But still I couldn’t find an answer from support that why this periodic waking up which exactly happens each hour related to VMM and SMB, assuming no laptops connected to NAS in the test period and no VM was running. Will update in case support answers me.
