First time NAS user and this was easy to setup. Shipping was fast as well. Utilizing as a Plex server and to backup data. Working flawlessly so far.

Exactly what I was looking for, at least until Synology makes a better unit with an Intel chip!

Just installed my new DS423 to replace the DS216se I have used for 5 years. Transferred the two (SHR) 4 TB drives from old unit with no data loss simply by moving the drives to bays 1 & 2. Installed an old pair of 1TB drives in bays 3 & 4 as Volume 2 to use as OTA broadcast TV DVR.Gave the new unit the same name I had used for the old one. My Win11 PC, my wife's MacBook Pro, my Android phone, and several TVs all work with the new server with no glitches.Two extra bays, much more memory, much faster processor, same management software I'm used to and painless setup. High expectations. 2023.05.02Ask again in a year.

I'm thoroughly impressed. I'm not going to get into the weeds, as there are plenty of reviews and videos you can wade through if you're looking for technical detail.It just works. DiskStation manager is easy to understand, use, and modify through adding packages as needed. I was buying this to use for storage and Plex, but found many more useful packages to use through Package manager to basically turn it into a baby home lab environment. Great sort of entry point into a slightly more powerful unit with 4 bays and expandability through RAM upgrades and NVMe. If you're on the fence, my recommendation is go for it.
I am not saying this is enterprise ready but for a home NAS under a thousand dollars it is hard to beat. I ended up putting two NVMe drives in it (storage and cache) and maxed out its ram which drove the overall ownership cost up but still worth it. Note: that to use an NVMe drive as a fast storage (and not cache) then you have to buy the Synology NVMe which is a bit pricier. For the cache NVMe I was able to buy a much cheaper drive that was listed as compatible (WD Black SN770) and offered a good price/performance ratio. The DS423+ has the Intel CPU in which has hardware accelerated transcoding that other models with AMD CPUs do not. The hardware transcoding makes it a much better option when using a NAS for anytype of media conversions or servers. Anyway, for some ... MoreI am not saying this is enterprise ready but for a home NAS under a thousand dollars it is hard to beat.

The hardware transcoding makes it a much better option when using a NAS for anytype of media conversions or servers. Anyway, for some reason Synology is moving away from Intel chips to AMD and this is one of the few offerings they currently release that has that. It made purchasing this model a very easy decision for me. The older model was great too and had others features this one doesn't but I wanted the ability to use NVMe as storage so I opted for the DS423+.
I'm only using this for backups for my primary NAS unit, but it's working out great so far. I use a custom ssh script to to the backups and it was fairly straightforward to set up ssh keys and such so rsync could work passwordless from my primary NAS for it's backups.The speed seems great, the UI is responsive, and the apps and features seem like they'll be useful in the future if I change my primary NAS to a Synology as well.I'm using WD RED drives (5400rpm) and the copy speeds are slightly faster than what I got with my old Qnap, which had a drive bay fail. That's why I replaced it with this one. My setup is in a RAID 5 configuration. With four 8TB drives it took about a day and a half to build it's initial raid setup.The company I work for has always used ... MoreI'm only using this for backups for my primary NAS unit, but it's working out great so far.

The first one was almost 10 years ago and it's still running strong for them (that instance is using the 8 bay model).Great stuff!
