Overall, the DS423 and DS920+ have very similar specifications, as they both have the same CPU, GPU, and similar external ports. However, the DS920+ has an advantage in terms of expansion, as it can connect to an expansion unit via eSATA, and it has M.2 slots for NVMe SSDs that can be used for caching. On the other hand, the DS423 has an advantage in terms of potential performance, as it can have NVMe storage pools, while the DS920+ can only use NVMe SSDs for caching. Additionally, the DS423 has the potential for a longer EOL support cycle than the DS920+. Ultimately, the choice between these two models will depend on the user’s specific needs and priorities.

Pros and Cons

The Synology DS423 NAS boasts several attractive features that make it a popular choice for those in need of a high-performing network storage solution. One of its major pros is its Nvme storage pool support, which allows for faster storage pool access and management, not just caching. Moreover, its Intel® Celeron® J4125 CPU, benchmarked just like the highly popular DS920+, includes a built-in graphics transcoding engine, which can handle several simultaneous 4K video streams with ease.

However, there are also some notable cons to consider. For example, the DS423 comes with DDR4 non-ECC SODIMM memory, which could be a disadvantage for those looking for more robust memory options. Although the DS423 comes with a 2GB DDR4 SODIMM, it is upgradable to 6GB, which may not be enough for more intensive applications.

Additionally, the DS423 includes only two USB 3.2 Gen 1 ports, which may limit external connectivity options. Furthermore, while the dual-lan ports provide up to 226/224MB/s sequential read/write speeds, the DS423 does not come with 10Gbit connectivity as standard, which may limit data transfer speeds. Users can upgrade the ports to 2.5Gbe, but they will need to purchase an additional card.

Finally, the DS423+ has a maximum HDD size of 18TB per slot, which may be a disadvantage for those looking to store large files or videos. Overall, the DS423+ NAS offers an attractive range of features at an affordable price point, but its limitations, such as the lack of 10Gbit connectivity and maximum HDD size per slot, may deter some users.

  1. Are we going to get an M.2 NVMe compatibility test for the DS423+ given you’ve already done memory? My old DS1813+ is on it’s last legs (time to retire after a decade) and needs replacement, predominately for Plex and Surveillance.

  2. Hello everyone, I bought a Synology 423+, installed the drive inside, but on first power up I smelled a strong plastic and burnt smell.
    The smell passed after few minutes and everything seems to work fine and in temperatures. I would like to know if this is normal.

  3. I hope you can help me!
    I have sooo many files on my pc and external SSDs lying around on my desk. About 6 TB with videos, pictures and documents. Now that I’ve started a YouTube channel, there is going to be alot of video files!

    All I want is a box with 4 bays (maybe go with two 12TB to start with), to store aaall of my files. I want to connect with a USB to my pc and have a decent speed when tranferring files from my computer and I want it all to be mirrored. The networking part is not so important to me. Is this Synology DS923+ for me? And what do I look for in a suitable harddrive? Thank so much and cheers from Norway!

  4. Am I missing something or???

    How is 2.0 ghz higher than 2.0 ghz?

    how is 2.7 ghz higher than 2.9 ghz?

    The J4125 has a higher base clock speed of 2.0 GHz, compared to the J4025’s 2.0 GHz.
    The J4125 has a higher turbo boost frequency of 2.7 GHz, compared to the J4025’s 2.9 GHz.
    The J4125 has a higher TDP of 10 watts, compared to the J4025’s 6 watts.

  5. Is there a suitable ( AC power cord extension for synology ds423+ ) would a 4 Pin DIN Connector Cable, 4 Pin DIN Male to Female Extension Connector Power Supply Cable for Audio Digital Devices (1 meter) possibly work ?

  9. Why would anyone, at this moment, buy DS423+, when DS920+ is still available, cheaper, with more RAM, and has ESATA port for further 5 HDD extension…
    DS920+ will probably get NVMe, in couple of months (when there no more to buy new), as Synology now has no “hardware explanation” (which is their main explanation that PCI-E 2.0 is problem)
    why it cannot be enabled (as same hardware 423+ has it)
    REPLY ON YOUTUBE

  10. I was able to pick up probably one of the last “new” ds920+ for $849 USD in April 2023. I probably would have went with the 423+ for over $200USD less if I had seen this first. I upgraded from a d218+ (I think) and wanted the GPU and extra drive bays for Plex.

  11. Cheers guys @NASCompares for your informative/experienced inputs vlogs. (I hate seagulls, too ;-)). You talk a bit fast in your presenting ‘style’ to my ear, however, if I missed what you’ve shared, I can rewind. :-). You certainly have ‘good’ energy/passion/experience! Thank you for that! You’ve helped me decide on what NAS to buy. (DS-423+) (suitably boring but exceeds my needs enough) and I will use your link to possibly buy via Amazon if price is OK next week. If I can’t share my gratitude in a small way via that route, I will send a donation. Many thanks. You also gave me a valuable ‘feel’ for which type of drive etc., to purchase and how to slowly build a NAS system without ‘overspending’/making mega mistakes., etc., ????

  12. I love(d) my DS916+ and considered getting a newer and bigger Synology. But since being forced to buy re-labeled and ridiculous priced OEM hdd/ssd drives I am out. TrueNAS Scale and a more potent while cheaper self-build server are my way to go now. Thank you Synology for the good times so far … but I won‘t come back. Hopefully many others think the same.

  13. If a drive isn’t on the compatibility list will it work with a warning or you can’t use them at all?

    I use some basic desktop Seagate in my old rn31400. Will I still be able to use them in a Synology Nas (obviously re formatted).

    So I can’t buy just any nvme drives to use. I would like to put 2 nvme drives , 1 for storage and 1 for cache. I was thinking some affordable ones like whatever goes for $80 for 1tb drives.

  14. Good Vid as usual. Still disappointed in Synology and their going proprietary. Currently have a 416play with HDD but really want another for redundancy. Simple of fact of not being able put in affordable SSD’s is a huge issue for me. Samsung 870 Evo 2TB drives are perfect and priced right. I wish they would just open them back up again….

  15. Ready to buy a NAS but I am torn between synology and asustor. From watching your videos, I guess in a nutshell it is a choice between superior software vs superior hardware for the money, respectively. As an Apple hw user (I use others including windows and Linux since I’m in enterprise “IT”) I’m a bit fed up with price gouging with proprietary hw when spending my own money. Is the software worth the expensive and proprietary hw both initial and future upgrades on the synology side?
    REPLY ON YOUTUBE

  16. NOPE… I’m trying to upgrade from an ancient second-hand Synology that admirably still works but is not compatible with the latest DSM software. I’m not going to pay top dollar for a repurposed model from 2020 with a cpu from 2019! I was waiting for the ds423+ to come out but I’ll wait for a sale on the ds923+ instead. I don’t know what Synology is thinking, but the ds423+ is dead to me.
    REPLY ON YOUTUBE

  17. I’m still using a DS414 at home mainly just for file/multimedia storage and CCTV surveillance station. Looking at this 423+, I can’t see a good reason to upgrade and I certainly don’t know why people with the last 1 or 2 generation models would even think of upgrading. For me, like many others have said, a lack of 2.5Gb LAN is a deal breaker. I want my NAS to last well over 5 years (coming up to 9 years on my 414 now) so it needs to be up to date / future proof and 1Gb LAN is not. Especially when you think a bare unit is like £500.
    REPLY ON YOUTUBE

  18. The 423+ is compared to the 920+ in this review, but even having only the 918+ myself I see no reason to upgrade. I wonder what Synology will have in store for us when the x25+ series are released in two years time. If it comes with a better Intel Celeron CPU and 2,5Gb ethernet on board I might consider the upgrade at that time. But I am leaning towards a 5-bay NAS in the future (now using SHR-2 with 4-bays which is a bit of a waste), so let’s see what the next Synology models will bring.
    REPLY ON YOUTUBE

  19. Synology hopeless tentative response to the angry Plex clients over the last releases, just obsolete hardware, stay away from this, chose any other brand with 2.5GB network and a NEW intel CPU with integrated graphics.
    REPLY ON YOUTUBE

  20. Essentially I use my 720+ for Plex and very little else. One drive as redundancy is fine and I use 2 x 8TB Red. Considering going 4 bay more for the extra redundancy of RAID 5 despite the extra drive cost. I send movie files through my Apple TV 4K so I understand that I dont actually need integrated graphics to handle 4k and different formats. But still, It feels strange not having integrated graphics…just in case

  21. @NASCompares Wondering when QNAP might get some love? I have been seeing emails over the last month or two so that I would have thought would have caught your interest? The Security Bounty alone I thought I was going to see one of your quick deliver videos… Even the updates for the OS in the last 8 months or so have been interesting.

  22. The CPU is fine because it’s a 423 series… The bigger CPU will roll out hopefully for the upcoming generations. This is the clearly the base model with base model hardware.

  23. I tried to resist watching this, but as always I couldn’t hold out. I am afraid that you’ll sell me on buying this NAS too. I’ve already got two on my list. Still deciding on which ones to buy.

  24. I want to have a NAS as a Media server, saving movies and Pictures. I’m still not sure what I need…lol. Money is not realy an issue, but don’t want to get something I don’t need. It will be in my Living Room, so it need to be quiet, hence I’m planning to use SSD’s only. I’m not sure if 4 Bay or 2 Bay due to back up (I know a NAS is not a back up system). So far I’m looking at the 4 Bay Qnap, (they look like something I put in my living Room).
    REPLY ON YOUTUBE

  25. Very level headed points, thanks. Absolutely shocking that the 920+ doesn’t support M.2 storage, though I’m not sure the 423 would have many selling points if it did!
    REPLY ON YOUTUBE

  26. The fact that its 1 gig is enough for me to pass, that’s just sad Synology. Practically E-Waste. Its so cheap to have 2.5 or even 1 10g. Really was looking forward to getting a smaller Synology NAS soon for redudant backups and camera server use at a different site but can’t justify the cost with the lack of the expansion
    REPLY ON YOUTUBE

  27. I’m thinking of buying one NAS for several purposes (Plex server, cloud storage, mail server, web server. I was looking for the 920+ at the right price, but now i have to wait and see…

  28. Synology is really becoming a PITA. Waiting for the DS222+ for what seems like years only to have a hobbled DS223, and a lacklustre DS423+ be released does not bode well for a DS223+.
    Sigh.
    REPLY ON YOUTUBE

  29. I’m struggeling which nas to choose …. 720+ is like 3 years old and probably will be dropped earlier with support. With the new x23 Family I don’t like the ryzen without the graphic chips and the high power consumption. Thinking with going with the 423+ because of 4 Bay and therefor the more flexibility.

    Would be happy for a tip of you guys!
    Mainly I expect phone and pc sync/backup with a little bit of docker (pihole)
    REPLY ON YOUTUBE

  30. The fact that the 2GB of RAM is soldiered to the NAS and only has one free DIMM that will only allow 4GB (6GB total) is a letdown. In this day and age why would anyone soldier the RAM making it unreplaceable is mind boggling. If it came with 2GB but both DIMMs could be swapped out would be the smart option so I have zero idea why Synology would do that. Even if they limited it to 8GB, that would still be better than what they did here IMO.

    No 2.5Gb is a letdown also. Even if it was 1 2.5GB and 1 1GB Ethernet port it would give users options. Don’t have a 2.5GB switch/router. Use the 1GB port but if you later upgrade to 2.5GB you could utilize the faster speeds as bonding 2 1GB ports doesn’t mean you instantly get 2GB/s speeds.

    The slightly better integrated GPU might be helpful for Plex users I personally always try to buy media players that won’t require transcoding but I also know that not everyone has that option and Plex can sometimes decide to transcode when not needed and can have a major impact, even when just transcoding the audio and not the video.

    If you watch Plex remotely over WAN, not over LAN then you are going to obviously need transcoding more unless you have great upload speeds at home and are located somewhere remotely with good download speeds but getting good upload speeds really is out of most users control depending on where they live.

    I also always use a bash script to create a RAM drive as my transcoding directory as you get better speeds than a Gen 3 nVme drives when using a RAM drive but the 6GB RAM limit kind of makes that difficult. Yes, RAM drives lose all data if there is a reboot or random shutdown but any transcoded data gets wiped out in that scenario anyways

  31. Guys, is there any alternative to Synology Photos? My primary use case for Synology is backup, not multimedia like plex. For Backup it includes photos on phone. Synology photos works like Google Photos a lot. Does any other brand do it? or maybe a one time payment 3rd party backup solution?
    REPLY ON YOUTUBE

  32. I expected Synology to make a move like this and dedicate only one new device for media use. Maybe their focus has shifted to businesses only. Anyway more of a reason to keep looking for old ds720 / 920.
    REPLY ON YOUTUBE

  33. It’s 2023, and most drives can exceed 100mbs. This is network ATTACHED storage, so is limited by the speed it can connect to the network. And they still use 1gbe ethernet. Utter garbage that belongs in the bin.

  34. [yawn] The Asustor4 sitting on my desk stomps it already, with the same CPU and same specs except the Asustor4 has 2x 2.5GB NICs that I’ve got bonded together at the switch and it’s been out for what, more than a year already?
    So far the only thing I’ve found wonky on it is it’s implementation of Docker. Even after hand-upgrading Docker and Docker-Compose and Portainer to the very latest versions, it still sometimes refuses to re-use the ports containers are using forcing me to have to “turn off” the Docker and Portainer plug-ins within the NAS software itself and then turn it back on and hand-restart the containers. Other than that it’s fine and handles a 32GB RAM upgrade just fine. I’ve since moved almost all Docker containers off it to a more-beefy UNRAID server running on ASRock’s X300 Deskmini box with an AMD Ryzen 7 5600G CPU in it and 64GB of RAM.
    48 containers running right now barely moves the needle on CPU usage. Of course it’s being backed up to the ASUStor4 NAS.

  36. Synology is tone deaf to users, they expect their resellers to keep selling to customers. Who cares if the client has to wait longer with their NAS that costs more than the competition. QNAP just released a bounty for security, along with the multitude of improvements in security… They seem to be listening to their customers, something Synology should take note of…
    REPLY ON YOUTUBE

  37. It’s 2023. NO built in 2.5GbE? Fail sauce, especially since no slot for upgrade. Was disappointed that the 923+ had no 2.5GbE either but at least in has an upgrade slot. QNAP is stealing Synology’s lunch, they had better get with the program or they will lose customers…the QNAP TS-464 is probably going to be my next buy. Goodbye Synology, I’m tired of waiting, you’ve lost.

  38. I’m not disappointed by the NAS itself. I wanted a “Multimedia” NAS, as you call it, because Plex is my streaming platform of choice and I wanted a NAS that could do everything I wanted from a NAS plus run Plex with hardware acceleration.

    However, I wish Synology would drop all their upgrades at once because after weighing my options (DS920+, DS923+, and DS1522+), I finally ordered a 923+ for storage and other NAS stuff I want, and a NUC to be my Plex Server. Then now the day before they arrive I find out there’s a DS423+ that I could have bought and saved some money… Not cool Synology. Not cool.
    REPLY ON YOUTUBE

  39. I’m glad they came out with this because it felt like they were really ignoring the home user that wanted multimedia. It’s a perfectly fine cpu for its purpose. I have the 920+ and the cpu has never held me back for home and small business use running surveillance too. Even with multiple people streaming movies it keeps up.

  40. People at Synology have $h1t for brains. Everyone is asking for decent NAS that is future proof and can play 4-8K w/ integrated graphics (I’m willing to cough up $3K no problem for i5) and they are trying to sell you this piece of $h1t hardware. Like really?! $crew you Synology! ????
    REPLY ON YOUTUBE

  41. Finally! Synology is giving the people what they want… kind of. They’re doing it grudgingly, and a bit stingily, but they’re doing it none the less. Since the DS920+ is getting more and more scarce, and expensive, this is the best option if you’re tied to the Synology ecosystem. Still, they could’ve at least equaled the Qnap Ts-464’s specs.
    REPLY ON YOUTUBE

  42. Bro I think you made a mistake — the correct model number for this shitbox is DS420- Again what a disappointment. Its like all those fools in shitnology corp get together and see all the feedback of what people want and then do the exact opposite all to save.
    REPLY ON YOUTUBE

  43. It’s almost like they found this device somewhere in the back of a container and decided to name it 423+ in order to still be able to sell it. It is however a good sign that they are still in the Intel Celeron market, but I will wait now to see what the x25+ series will offer in two years time hoping for a real update. Until then my 918+ will do fine. Thanks for the update!
    REPLY ON YOUTUBE

  44. The consortium that has its hands on the 10Gbe technology is milking the NAS companies and ultimately us consumers. These few IP holders pushed 2.5Gbe very late in the game and this is now blocking wider adoption of 10Gbe and keeping it artificially high priced for everyone. I guess 100 MB per second is fast enough to stream some shows and movies for a small household. I guess nvme drive speeds that are 60x faster are not needed, but at least that technology wasn’t suppressed…

  45. I wonder who decides at Synology regarding new hardware, whoever the team is needs the sack or maybe do some marketing ,then you will know what people want rather then bring out very similar hardware to 2020
