Can I use NVME SSD for storage pools instead of cache?

Sounds like Synology now supports NVMe volumes. But only if you use their own NVMe SSDs. This is to be tested soon.

  1. Synology SNV3400 series M.2 NVMe SSD drives can be installed through the built-in M.2 slots to enable SSD caching or create SSD storage pools. Drives are sold separately.

70 thoughts on “Synology DS923+ 4-bay 10GbE NAS now officially released

  1. I do not have much NAS knowledge. I want to put 18Tb video on a NAS. 80 percent 1080p. The rest is 4k and this will become more in the future.
    What would you guys buy ? A 923+ or a 1621+ ? Or a different NAS ?

  2. Hi, I put in my DS923 2x4TB for private files, 8TB for Plex and Emby, SSD for VM…and 256GB for cashe. I just want to say that everything is working great. At first I put OpenVPN and run Plex and it was OK. Sometime it has little of lag …but today I install Emby and reallized that Emby is working much faster than Plex. I do not know what is going on but difference is significal. I run most of movies and shows in 1080o and that is OK for me. I am testing with Emby all day with or without OpenVPN and it is working great. I can say now that I am really satisfied. Synology DS 923 is very good product…. for media, file backup and many, many things. Best regards.

  3. Man I haven’t watched your videos in a while and I swear you talk even faster now. It’s almost incomprehensible at times especially if you get excited. I don’t know are you on a time crunch or something? Or do you film these close to dinner time and you want to whiz through so you can eat?

  4. I just purchased the 923+ last weekend… but it’s just as a hyperbackup vault. Keeping my 1821+ as my main plex server. Wanted the qnap but as only recently moved from self-made NAS with hardware RAID cards, stayed in the ecosystem for now (it was SHR that made me go Synology rather than QNAP/Truenas ZFS)

  5. I was going to buy it (I made the order and canceled it few hours later) until I discovered the new “HD compatibility list policy” and how my two WD RED that are compatible in my old Synology NAS are not in the list anymore. No more Synology products until they revert this stupid policy and the path that their are taking with these actions. Good way to ruin the reputation of a good company.

  6. I have followed you for a long long time, and i have been running truenas/freenas and now i wanted to switch to a smaller box, for a apartment homelab.
    I got the 923+ becuase of its ryzen processor, more importnat for the pcie lanes it offers and for ecc ram.
    While it seems that the market is big and there are a lot of choices, there really arent many for a 4 bay nas, there are the qnap 464, terramaster whater that have the celeron cpu and nvme that runs at x1 .
    The only other variant is the qnap 473a that has a better cpu and faster network + ecc memory , but it’s much more expensive.
    So for that the ds923+ seems to be my choice.
    Please continue with your outstanding work !

  7. I’ve been waffling between the 923+ and the 423+. I didn’t really need the transcoding so the 100 US Dollar difference was decision factor. However, March 31, 2023 both Amazon and B&H Photo dropped the price for the 923+ so it is 10 US Dollar more than the 423+. That made the decision, order placed — using your link. Hopefully that worked.

  8. I think I bought my last Synology NAS last summer. The sheer wisdom of Synology to not accept other manufacturer’s nvme drives and to not support 2g5 or 5 Gbps as standard is unacceptable. It’s a solid OS , I’m using it since my first ds-101. I’m feeling a bit sad to know that I have to switch. I just have to.
    I love the attention of you for the streaming aspects like Plex support. I think you were way to kind on this 923+, though. Air flow , ECC etc don’t make up for the short comings.
    Clicked the bells and I keep following you. Thanks.

  9. I was going to buy this as my first NAS as I run a small electrical business and also run a PLEX server with only a handful (around 40 titles) of 1080P MKV files.
    I use my laptop for my business use but, as my business and client base are expanding, I’m finding I’m maxing the storage capacity of my laptop which now runs like an old Ford Cortina where it once ran like a Ferrari.
    My current PLEX server is an Nvidia Shield (2017) so I guess I could use that to process any transcoding etc etc.

    I would use 3 x 6TB Toshiba M300’s in a RIAD1 configuration which I feel would be ample space for at least another 5 years or so.
    I do plan to create more MKV files but only in 1080p although I do own an LG C2 OLED so 4k is do-able….

    Any thoughts??

  10. Lol one of the first real tech reviews I’ve seen. Giving a real review with real pros and cons not “fake positive cons” really help solidify the information as being useful. Great job

  11. Something that I don’t think has been mentioned is physically transferring HDDs from an older Intel NAS to the DS923+. I believe you could transfer drives from, say, a DS918+ to a DS920+, but will drives from a 918 be accepted in the 923 considering it’s a Ryzen CPU?

  12. I am a Sports photographer, and I’m gathering more and more external drives as time passes, so it’s time to go NAS. Which one would be the best for photographers? Just to put the files, and have security on it? I spend around 6/8 TB per year. Using 2021 27’’ IMac. I need fast reading as I work the photos inside the external drive not in the computer main drive. Cheers. Happy new year

  13. Looking to upgrade my NAS, but I don’t know man. I think I’m done with Synology. They just seem underpowered and overpriced these days. They have a bunch of models, but none seems to be a good value anymore. At least for me.

  14. According to cpu-monkey and Geekbench 5 the R1600 is even slower than the J4125 in multi-core benchmark. That makes sense since hyperthreading / SMT can not make up for real cores. Also considering the high power consumption, I think it’s the wrong choice for this kind of device.

  15. That was very helpful, thank you! I’m looking for a NAS that will enable me to do video intensive video editing of 4k h264 files. I will do that on 2 macs (imacPro 2017 and MacStudio 2022). So I assume 10GbE is a must have for a NAS. I don’t need all that much storage space because I archive most of the stuff that I finished working on.
    Do you think the DS923+ is the way to go, or would you recommend something else?
    Any help is greatly appreciated. For a layman all the NAS options seem a bit overwhelming.

  16. Maybe I’m missing something? I run a synology nas and use the infuse app for apple on all my apple 4K’s for media streaming. What am I missing out on not running plex? I’m guessing all the magic is happening inside the phone or Apple TV because my nas or media never lags when watching 4K hdr10 or Dolby vision title. Seems like so manny people worry about plex performance is this just because they don’t use Apple devices? I tried plex it was pretty bad at stream when the nas needed to decode or whatever.

  17. Looks like Synology have discontinued the 920+ for some reason (no longer on their website) so looks like no option but to purchase 923+ now for the normal person maybe have to find another brand instead (was looking for 920+ on a Black Friday deal but seems no one really offering it. Oh well time for re-think on what to do now

  18. So how will the 923+ handle surveillance station without the embedded GPU? 6 x 4K cameras for example. Is this going to be able to record and handle remote viewing on i devices? Better or worse than the 920+? I don’t have or want plex, just curious about the surveillance video aspects.

  19. This is not a review but a sales pitch. Stick to FACTs and not hopes or suppostions. Very disappointing ‘review’, with little mention of the Synology lock in of added gear to make it work. No 2.5 or 10G network as standard. What a joke.

  20. I was waiting for this to replace my aging DS412 which cannot run VM’s or Dockers which I need to install Home Assistant (home automation). However, a 2 core CPU does not mesh well with virtualization (I agree that threads are not cores …). The lack of a 2.5 GB ethernet port and the higher power use are just the final nails in the coffin for me, I’ll be skipping this model and hang on to my DS412 for the moment …

  21. So, not only is it missing 2.5gbps, and has a proprietary insert card for 10/5/2.5 wich will cost closer to 100-150 euro, it requires their OWN EXPENSIVE DRIVES.

    Im not expecting the “base” ds923 (none-plus) to support essential features, like the expansion card, virtualisation, ram upgrading.
    They are going to force people who have a 920+ or similar to switch to another manufacturer all together.

    Synology is greedy and will loose alot of favor in the home user department, wich in long term will hurt them as people dont get used to their software/hardware early.

  22. This „before you buy“ helped me alot. Conclusion for me as multimedia guy: wait and hope that Synology will release a DS with integrated GPU or looking to Qnap and hope that they make their NAS SW secure regarding Cyberattacks… But how long do I have to continue waiting for that …. Maybe another two years ????????

  23. According to the spec sheet the NVMe SSDs can be used for “additional storage pools.”

    The Synology DS923+ is a capable 4-bay NAS solution that can be adjusted and expanded as your needs change, with optional support for up to nine drives, faster networking, and NVMe SSDs for caching or additional storage pools. Powered by Synology DiskStation Manager (DSM), it offers a flexible all-in-one solution for data sharing, synchronization, backup, and surveillance.

  24. Thanks for the video. Everything about this device tells me to change to QNAP after 15 years of using only Synology. The only thing that still has me on the fence is that it will not be as compatible using my old Synology for backing up from my new NAS.

    Using it mainly for media the AMD processor is a big minus. I’d consider the 920+ which keeps my new CAT7e network unused. QNAP doesn’t have DSM. Dilemma.

  25. Out of the box, this is mostly a downgrade or level with the prior version. Worse power efficiency and limited support for third party drives are the ones that affect me, and it grates that I have to pay relatively a lot extra for up-to-date networking. I just want a big, simple, super fast storage engine on the network for two photo / video editors. I could make the DS923+ work, but I’m going to take a hard look at QNAP and others. I love my DS218j, which taught me the joys of NAS. But Synology just seems a bit hostile to its customers.

  26. I’m glad instead of doing a long form 30-40 minute review you did a much shorter 33 minute video ????. Haha I’m just messing around, this was really helpful. I’m on the fence with the ds923+. I am a heavy Plex user and some family members use my current server with transcoding outside my home, but I use an Apple TV 4K and mostly do direct play myself. I have fast upload speeds, so maybe since I’ll be able to connect this over Ethernet, it’ll be fast enough for any family members to also direct play. The overall faster CPU and potentially faster Ethernet ports seem like nice upgrades over the 920+. Decisions, decisions. Thanks again for the info! I’ve been following your videos over the last couple of months as I’ve been trying to narrow down my choices for a new, first NAS.

  27. Short answer is no. This NAS is a fine file server, but way over priced. For less money you can get a Terra or Asustor and get the same performance. If you wanted to go prosumer, QNAP really is the only way to go. I went with 453E and it works extremely well and is just amazing in all that it can do. Sadly Synology is going very cheap to bump bottom line and is focusing on file serving.

  28. I bought the Asustor Lokerstor Gen 2 4 bay and it’s really fast. I even enabled to generate frames in Plex and it did that flawlessly while downloading data with download manager and watching a movie.

  29. Thank you for saving people from big purchasing mistakes! When I saw it didn’t have an Intel CPU, I thought about Plex Transcoding performance immediately. I would like to see benchmark comparison with the DS920+ for Plex performance…please ????

  30. For Plex users that still need to transcode I think the best option would be just to use the DS923+ as a file server . Pick up an 8th gen or newer intel NUC for transcoding duties and point the folder share to the DS923+ where your Plex media would be stored.

  31. Can I have a TLDW? Buy 923 or 920? 923 has ECC, more energy consumption and faster clock speed. So 920 right? For having more dedicated cores and more importantly that sweeet sweet transcoding action

    Edit: I cant wait for the upgraded models for 1622+ 1622xs+. Would it be alright to expect them to release these in a years time or are these already new?

  32. Noticed this on Synology’s website on the DS923+ product page “Synology SNV3400 series M.2 NVMe SSD drives can be installed through the built-in M.2 slots to enable SSD caching or create SSD storage pools”. This does look like Synology will enable NVME will be allowed for storage pools.

  33. Thank you very much for your video and your invested efforts!

    Could you tell me, with how many tablets/mobile phones could you use to access and watch videos on the NAS from the Internet?

  34. On the RAM front, I’ve been running my 920+ with 20GB RAM (Timetec 16GB stick installed) for months without an issue. Other things will be a bottleneck before the RAM for me. When I had just the basic 4GB, RAM was being fully utilised for some operations but 20GB I’ve never seen pushed. At least when I’ve checked.

  35. You can already turn the NVMEs into a storage pool. Pretty straightforward as RAID1, and a gamechanger for putting things like Plex or Docker directly on that NVME storage pool. Blazing fast!

  36. Always, thank you for great video sharing. I just bought my 920+ last week, upgrade from ds214play . After compare and found the new features offer in 923+ is just not what really need the wait.

  37. Eddie was right on the button! this is a low level business NAS, rather than a Mid/high level SOHO/Prosumer user! Big pass for me. I so much wanted to upgrade next year! Not happening for me now with this model, I’ll stick with my 918 for now, no way going to Qnap (just because of DSM, but for how much longer?).
