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.

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.

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.
The smell did not return again.

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!

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.

  Thank you, I have corrected those errors:
  Both CPU has the same base frequency and TDP
  J4125 has two extra cores (4X2GHz)
  J4125 has a slightly faster GPU chip
  The J4025 has a higher turbo boost frequency of 2.9 GHz, compared to the J4125’s 2.7 GHz.

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)

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.

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?

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.

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.

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

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

[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.

Hmmmm …. it’s as if the DS920+, DS720+, & DS220+ got-drunk, has an orgy, & 9months later the DS423+ was born ;). Soooooooooooo its plex performance should be ~about the same as:

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…

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.

Leave it to Synology to be passive aggressive when releasing a NAS. You can feel their distain towards media users with these specs.

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.

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.

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! ????

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.

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!

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…
