The Synology DS925+ NAS Revealed

The Synology DS925+ is a refreshed four-bay NAS that builds on the foundation of its predecessor, the DS923+, by introducing enhanced processing power, faster network speeds, and updated expansion options. The most significant change is the shift from the AMD R1600 dual-core, four-thread CPU to the AMD V1500B quad-core, eight-thread processor, which was previously used in Synology’s higher-end six, eight, and twelve-bay NAS models. This upgrade provides substantial improvements in multitasking, virtualization, and Docker performance, making the DS925+ an even more capable solution for small businesses and advanced users. It still ships with 4GB of ECC DDR4 memory, which remains expandable, ensuring users can scale performance as needed.

(Specs below based on the DS925+ Information shared online by 3rd parties, with DS923+ specs that are likely correct)

One of the most notable upgrades is the move from 1GbE to dual 2.5GbE network ports, which finally brings Synology’s mid-range NAS lineup in line with modern performance expectations. This enhancement allows for significantly faster file transfers, improved multi-user access, and better performance when combined with SSD caching through the device’s dual M.2 NVMe slots. These improvements are particularly relevant for users handling large data sets, cloud synchronization tasks, and high-speed backup operations. However, a controversial change is the removal of support for the E10G22-T1-MINI 10GbE upgrade module, which was available on the DS923+. While the inclusion of 2.5GbE networking is a welcome step forward, the inability to upgrade to 10GbE might limit the NAS’s appeal for users who require higher-speed networking for large-scale data operations or high-bandwidth applications.

Another major shift is in the expansion connectivity, where Synology has replaced eSATA with USB-C for connecting external storage. The DS925+ now supports the new DX525 expansion unit, allowing users to increase their storage capacity while benefiting from a more universally accepted interface. However, one peculiar specification that has raised concerns is the listed transfer speed of 6Gb/s for the USB-C expansion port. This is inconsistent with standard USB 3.2 specifications, where USB 3.2 Gen 1 supports 5Gb/s and Gen 2 supports 10Gb/s. It remains unclear whether Synology is implementing a proprietary solution, using a USB-to-SATA conversion method, or limiting speeds internally for stability reasons. Given Synology’s tendency to restrict third-party drive support, it will be interesting to see how this expansion system performs in real-world applications.

Overall, the DS925+ is a meaningful, if not revolutionary, refresh that brings solid improvements in CPU performance, networking, and expansion capabilities. The quad-core V1500B CPU, upgraded 2.5GbE connectivity, and continued support for SSD caching make it an attractive choice for businesses and power users focused on file storage, virtual machines, and containerized applications. However, the removal of 10GbE upgradeability and continued lack of an integrated GPU may deter those looking for high-speed networking or media-focused functionality. If Synology maintains pricing consistency with the DS923+, this update will be well-received, but users seeking greater flexibility in networking and GPU support may need to explore alternative models in the 2025 series.

      1. It seems to me like Synology is trying to balance the effects of technological progress by applying some form of reverse Moore’s Law. In a few more years, their refreshed product line will match the performance of my 10 year old DS214. Tired of waiting for them, time to look elsewhere.

      6. My guess is the quote of USB at 6 Gb is a mistake and somebody was thinking of SATA… to engineer 6 GB USB wouldn’t make any sense, especially given how little effort they’ve put into these upgrades
        REPLY ON YOUTUBE

      7. Is it true that Synology now requires you use Synology branded drives? If I wanted to buy the DS1825+ and put in 8x 4TB SSDs, must I use Synology?
        REPLY ON YOUTUBE

      9. Still not seeing any reason to move up from my Synology DS918+ which I bought just after launch. Sorry Synology, your software is amazing and I’ve had no issues with any of my previous purchases. I guess I’m just not your preferred customer anymore.
        REPLY ON YOUTUBE

      10. If a new one with ‘same hardware’ just 2.5gbe costs much more than the usb to 2.5Gbe adapter, people should might consider buy 2.5Gbe adapter only and save money (if they already have one) and if they don’t, maybe by an old model, and if want, buy 2 adapters one as backup ???? and still saving money
        The prices are ‘crazy’ and for example here in brazil, they’re totally crazy.

      17. Underpowered and overpriced.
        With all those new NAS (ugreen and others) I don’t know why one should choose Synology at this time, apart from the software (but we have truenas, unraid…)

      19. i feel so bad for selling my old nas, this is just shit, no 10GBE ON THE 1825???? JOKE COMPANY, its time to buy unifi unas pro with 2bay synology for phone backup only
        REPLY ON YOUTUBE

      21. Fantasic news. Thanks for putting this out so quickly – it’s made my day (sad, I know!). I use a 920+ and skipped the 923+ because I could not believe the dumb and short sighted approach by Synology by not including 2.5GbE on it, a MASSIVE fail, IMO. But this 925+ looks like it’s going to be my next NAS, BUT, will I be able to remove my 4 drives out of my 920+ and just drop them in to my 925+ when it arrives???
        REPLY ON YOUTUBE

      22. Intel J4125, comon Synology, with N100/305 out there? i understand not moving right away, because of their policy into having more stable setups, but by now the N100/305 are probably the best choices for small server.
        REPLY ON YOUTUBE

      25. For the expansion units, the USB-C port is probably connected directly to the processors of the DS and the expansion units, but the drives are all connected with SATA protocols and hardware, so they can’t promess any more speed than SATA 6Gbps even if the port is 10Gbps. Maybe the port is USB-C 10Gbps and can be used for other means tho?
        REPLY ON YOUTUBE

      26. Moved to Terra master F4 424 last year, after being with Synology since my very first NAS donkeys years ago. Looking at this refresh it was still a good move. I can use it with TOS6 or anything else I choose, pick the drives I want, Synology these days is just over priced Cr@p. Love this channel and thanks for getting up so early.
        REPLY ON YOUTUBE

      28. meh, if it aint broke dont fix it.. they probably have a huge stockpile of those old CPU’s they are trying to get rid of. For storage.. they are more than adequate.. for people that want more and more out of their appliance.. docker.. vms.. this isn’t the right choice.. but it never was..

        lets hope they create a new series for power users like that.. other wise.. you gotta build something yourself.

      33. Just set up my new DS923+ yesterday…… Would have liked the 2.5gbe but doesn’t really look like I’ve missed out on much. And still have the 10gbe option should I ever actually need it!
        REPLY ON YOUTUBE

      36. Two x 2.5 is much better than 4×1 in LAG. While 4×1 LAG gives you a combined 4Gbbps of bandwidth its only 1Gbbps PER STREAM. Dual 2.5’s in lag gives you 5Gbbps aggregate, which yeah is a 1G upgrade, but ALSO gives you 2.5Gbps per stream which is a huge improvement.

      38. Well, saying I’m disappointed is a big understatement!
        I feel even more disappointed than when they announced the RS1821+ without nVME slots! ????
        I think it’s time to move on…
        REPLY ON YOUTUBE

      39. Been running multiple Synology NAS units since the days of the DS207. With the other competitors listening to what their non enterprise users want, I can’t help but continue to look elsewhere for my daily driver NAS. Having a UGREEN and QNAP, those both continue to just look better (if their software can be as reliable).
        REPLY ON YOUTUBE

      43. I own a Synology and am looking for a 2nd NAS. Will not be looking at Synology for that. I am interested to see how UGreen progresses in its app development. Would be nice to have an update on their progress.
        REPLY ON YOUTUBE

      44. Hmmm, just bought Ugreen with Intel u1235, thanks synology for reminding me, why i migrate from my 1522+… Like putting new carpets to the car… and call it refreshed new version ???? Ugreen allow me use any ram i want (not overpriced synology one), allow me to create volume on nvme, allow me install other os and the EXOS drives are a bit quiter in ugreen (guess that metal chassis with a bit of space on synology doesnt help reduce noise).
        REPLY ON YOUTUBE

      46. Honestly, if I need a new device, I’ll look elsewhere. Yes, I use it to back up laptops and as a media hub for photos and videos. Shame as I have Synology mesh as well, this will also go to a different supplier in due course
        REPLY ON YOUTUBE

      47. Nothing compelling. Seems my RS1619sx+ remains a “current” model. Wish it had WORM/immutable shares, but as far as I know, it still dos not. If I had to buy a desktop NAS right now, it would probably be UGREEN. Their OS is still evolving. It’s not bad in its current form and I am free to put something else on the box.
        REPLY ON YOUTUBE

      49. Kind of hard to entertain an upgrade when I’m using a DS712+ still (and also a DS420+; both are NAS ONLY and running nothing else)

        It’s clear that my upgrade path will be a (rubbishy in some ways) custom-built NAS out of some 2U case. Trick there is to be able to fit several 3.5″ mechanical hard drives, decent cooling for the mainboard, and upgradability to faster than 1Gbps on MY terms. Not everyone can afford optical or even a copper Nexus switch to get 10Gbps; yes I realize I’m an infra snob and “thing that works like Cisco” is what I expect in infra (10Gbps is still stubbornly expensive at scale, at least at home)

        I miss ZFS and I want my next NAS solution to support it.
        REPLY ON YOUTUBE

      51. Well, looks like my ds223 will be replaced with a unifi UNAS pro…
        Synology really screwed the pooch here..
        UNAS has a A57, 7 bays, and 10g for $499…
        REPLY ON YOUTUBE

      52. 1825+ with dual 2.5Gbe would be more than enough for most users, so it’ll be ultimately about the price – if it doesn’t go any higher than 1821+ then it may remain competitive on the market, but if it costs any penny more, then it’s not worth over older model at all
        REPLY ON YOUTUBE

      54. Went over to Unraid and built my own micro box with potentially 6 bays. Never going back to the many rip off manufacturers like Synology. I am gobsmacked at their attitude and almost zero technology advances

        But love this channel and always come here to keep up dated
        REPLY ON YOUTUBE

      57. I am excited about these new releases. Maybe the 22, 23 and 24 units will come down in price and I can buy one of those! In the mean time, where do I look for used units to purchase cheap? Some of us are on tight budgets. Our CFO has an iron fist of NO when it comes to new technology purchases. (CFO=Wife).

      62. Glad I went with the T6-423 from Terramaster. Been pretty good for what I need it. HDHomeRun Docker and Plex, iTunes Library location.
        I encode the videos for iTunes and then Plex Library picks up the folder contents.
        So streaming iTunes videos to AppleTV Plex Client or AppleTV client from Apple.
        As such the NAS not doing any transcoding.
        REPLY ON YOUTUBE

      63. I currently own a Synology DiskStation918. Over the years, I’ve noticed that Synology has been gradually locking down their hardware, which has been a significant deterrent for me. I’ve been keeping an eye on the DXP4800+ since its release last year, but it has unfortunately been unavailable in the UK. I reached out to UGREEN regarding a potential UK release of the DXP4800+. Within 10 minutes, I received a confirmation that the product should be available in a few weeks, subject to any unforeseen delays.
        Bye,bye Synology. I’ve moved on, unlike your hardware.
        REPLY ON YOUTUBE

      67. I’ve got into Synology in 2020 with a DS220+ for home use, plex and photo archiving. I won’t consider Synology for future upgrades and I’ll keep an eye on other OS and hardware. The N100 and N150 looks awesome at least for me and I’m looking forward to HexOS. Looks like this is the aim of Synology, getting rid of home users, literally anything alse around is more convenient
        REPLY ON YOUTUBE

      75. Moved to ASUSTOR LOCKSTER 4 GEN 2 as I feel synology hardware is lot more older than its compitetors. atleast lockster gen 2 came with N5105 processor which is an older ver but not as old as synologies.
        REPLY ON YOUTUBE

      79. LOL, what a joke. This just confirms I will never buy Synology ever again. They are living under a rock.
        No reflection on your great videos…thanks for taking the time to share all the helpful info.
        REPLY ON YOUTUBE

      81. I’ll stick to my super old 1812+. Very few has changed in the meantime, they are still using outrageously outdated hardware, unbelievable.
        REPLY ON YOUTUBE

      85. They really don’t give a sh¡t about the home/enthusiast/small business market do they? “Let’s make the very least, minimal changes, and up the year number to make it look like it’s a newer and better thing”. They’re like my ex-wife was, always late, always a disappointment, and always trying to tell me they’re better and more value than they really are, and they think I’m a sucker and I’m going to come back because they do that one thing very, very well! Seriously though, if the DS15 doesn’t support 10GbE and the only change on the DS18 is to 2x 2.5GbE, I reckon I’d probably be better off getting discounted 22+ and 21+ units. At least you were up before the seagulls though!
        REPLY ON YOUTUBE

      87. Something tells me that they have not upgraded Marvell RAID chip in DS625slim. I would not be surprised if 6 SATA lanes/disks were still connected to the CPU via just two PCIe 2.0 lanes effectively creating a bottleneck of 1000MB/s. Sadly no DS419slim upgrade on the horizon.
        REPLY ON YOUTUBE

      90. Another drip, drip, drip…. Higher prices for the negligible performance improvements. The NAS market all but stopped 5 years ago. Same memory, same CPUs, same slow NICs on the lower end…
        REPLY ON YOUTUBE

      91. Still no N100-based 2-4-5-bay solutions for home market? Bonkers. I guess this settles it – will go for a selfbuilt. Only question is if I’ll use my (finally) retiring desktop system based on i7-4790 or I’ll pick up one of those fancy N100-based boards.

      97. oh well…. cant say im not suprised. i guess thats goodbye to synology and my DS1813+. I waited as long as I possibly could. Hello 45Drives HL8.
        REPLY ON YOUTUBE

      98. Urgh, i just bought a 923+ a month ago because i was tired of waiting and thought they’d skip 2025 new models. I wish they would make a cheap 2.5Gbe upgrade card for the 923+.
        REPLY ON YOUTUBE

      99. Thanks for the vid, Rob. Yet again, it seems as though Synology has not listened to it’s customer base. My first Synology was a DS211J and bought 2 more since then. Time to turn my back on them and go with something else to upgrade my Plex server.
        REPLY ON YOUTUBE

      101. The DS923+ and DS1522+ have both gone up in price by 20-30% down under lately. For Synology to take away 10Gbe seems absolutely bonkers. For photography and even office work file server 10Gbe is essential. 2.5 Gbe doesn’t even facilitate the full read/write speeds of a 4 or 5 bay NAS with spinning rust. With 4 synology HAT3100’s my DS1522+ runs around 600 MB/s via 10Gbe without any NvMe cache. Why bottle neck these devices by giving no way to get data off at the bandwidth that a bunch of spinning rust can facilitate?
        REPLY ON YOUTUBE

      104. Jeez its a bit disappointing. My old NAS is so overdue for a upgrade but these are not much of a step up in fact in some ways they are worse. My old 4 bay st least still had integrated graphics that works a charm on Plex but is really struggling with modern codecs like AVI.

        Really wish someone will make a NAS using a modern chip that has all the latest codecs supported especially AV1 10bit encode and decode
        REPLY ON YOUTUBE

      105. The recent moves in software, discontinuing Video Station, etc make me nervous getting a Synology. I’m more likely to buy a UGreen (when they finally get released in the UK) at this point.
        REPLY ON YOUTUBE

      106. Sounds like Synology have just stopped trying in the home / SMB segment. I won’t be investing in a system using dated parts (but which I would want to run for many years into the future) and run by a company that doesn’t seem to care about what (it appears to me) a lot of customers want. Even taking into account software and price, I was already leaning towards QNAP or Asustor etc., and I would still pick their current gen hardware over the new Synology offerings in a heartbeat. Can’t wait to see what these other vendors offer later this year.
