    4.0 out of 5 stars No Plex Server support yet but works great!
    Reviewed in Canada on August 19, 2023
    Just bought one, and compared to ds220j it had more ram and an updated arm cpu. If you don’t need hardware encoding (in 2023 you shouldn’t other than unique cases) and will not use VM or very advanced feature this unit is very affordable to get into Synology NAS world. Other brands like ASUSTOR or QNAP have more power and features for your money, but Synology ecosystem is very streamlined and optimized. I hope Plex Server official support comes asap, using Emby for the time being and exploring the features and recommend everyone to get into their first NAS.

    I am very happy with this baby Synology. I use it to sync important directories from my laptop and it does exactly what I need to. It has a myriad of other functions that, to be honest, I don't use. I make use of it's basic functionality and that it does exceptionally well.

    5.0 out of 5 stars Does exactly what it should, straight out of the box, painlessly.
    Reviewed in Australia on November 4, 2023

    This is the least painful setup / configuration experience I have had with any product (including Apple devices) in my entire life.

    After tossing two SSDs into the internal drive bays, closing it up, plugging it in and pressing the power switch, the DS233J detected both drives, and proceeded to initialise and configure itself pretty much on auto-pilot (while still providing lots of options to fiddle with, if desired, along the way).

    The web-based setup assistant is idiot-proof (witness myself; exhibit A!), and the only extra step involved in my particular case, was quickly installing the Media Server app from within the web-based management environment (said installation took around 5 seconds, total), at which point, my smart TV immediately recognised the DS233J as a valid input source, and away it went, streaming movies, photos, etc.

    Network access to the RAID array in the NAS was seamless, from all devices in the house (Chromebook, Mac, Windows PC), and everything functioned as expected, without any further config. hurdles.

    This thing is small, lightweight, very very quiet (it does have a fan, but it's barely audible even up close), and the setup process and management software are absolutely superb. Even if you barely understand anything about NAS's, filesystems, RAID setups, or DLNA servers, you can have this device up and running within just a few minutes.

    Basically, it does exactly what it's supposed to, and does it in a way that should make Apple jealous.

    5.0 out of 5 stars Up up and away!
    Reviewed in the United States on June 26, 2024

    Finally took the plunge into getting a more solid backup solution. I have been backing up stuff for YEARS due to a heavy lost back in the 90's. So since then I've started to back up religiously!! The sad part is back in the 90's the HD was like what... 3GB maybe 6GB. Now you got TB's. Well more stuff on 1 disk, but if that disk dies or fails.... you are SOL right. Well, I've been just backing up from drive to drive piggy backing if you will and finally I decided to try a better solution with this drive/backup system.

    It was recommend by someone in IT as pretty decent and it didn't break the bank! So I got it, came pretty fast I think 4 days max along with a 14TB drive (different order) this thing doesn't come w/ a drive just so you know. Setup was pretty easy, but the interface is something I was not familiar with, so it took a little bit to get use to it, but now after a month or so its just doing its thing since I have it setup.

    PRO's - Nice design (looks nice), easy to open/close get your drive in etc. It also has USB port in the back which is excellent! I hooked up all my (old drives to be backed up) and once setup, I was able to transfer easily from those drives to my big 14TB. So pleased with that. The webpage/browser access is ok, lots of stuff which I have no clue how to use or why I would use it... Just wanted a drive that I could "share on network" without having to have it hooked up to a pc/laptop running 24/7. This does the trick as it has a network cable and is accessible without a PC being hooked up to it. *Although I haven't figured out how to access it lol* But hey any access I need I am at home so all good for me. For your techies you can probably figure out the offsite access fairly easy I am sure. Ohhhh one feature I did understand and was able to setup really easy is this power on/off of the drive. You can setup a power off and power on time, which is cool and I think that helps because I have it turn off like midnight and then back on around 7am. So it gets a little breather..... as I am sleeping. hahahahaha

    CON's - Hmmm the software is bit complicated for my taste, but maybe these types of setup are ALL like this so it may not be a huge CON if that makes sense. The stuff I needed to figure out and to use I did, so if you are along my speed (know enough to be dangerous) you should be fine. The only CON and its not huge, but it drives me crazy is this one. So when you plug in a USB drive to the system.... it calls the drive USB SHARED 1. I'd like to change the name to something I can remember... so my naming convention was out the window and luckily I still had my old laptop hooked up to figure out what drive what was so I could AT LEAST keep the (drive letter) the same. That I was familiar with so a little pain, but workable.

    Overall.... SOLID! I'd get this again for sure! If you don't have the $$$ for a larger drive system (like 4) then this TWO drive system is affordable and solid so far. I think there is even a RAID function for cloning drives in the system if you want to do that, but for me I just wanted to backup the other USB drives I had to another drive and I've done that. So I have 1 slot open for a drive to expand when the time comes. Maybe when I get bored I will look into the webpage "apps" and see what all I can do. There are photo apps and things which I think will let you share photos.... its basically like your "own" personal cloud although I don't have it setup for access like that it would seem. I did however get my PLEX stuff over to the drive and so that's cool!

    Hope this is somewhat helpful for at least those who may now be as knowledgeable like myself with these setups. :-)
