Sort of on the fence about this one...it's a NAS
I wanted to utilize a couple of my large HDD as a NAS (again). The older model that I was using wouldn't accept the size drives I wanted to upgrade to and did not want to continue with drives located inside PC, dealing with the various backups, mirroring, and so forth. Nothing in particular critical or sensitive being stored, just wanted easy access from any device in the house. This unit was highly suggested by various sources and reviewed high so figured it would be a shoe in. I am FAR from some super IT pro, but certainly know enough to be dangerous (to myself) and have dealt with various NAS/FreeNAS/sharing units and setups over the years. This unit didn't seem super intuitive to me insofar as setup. First off, make sure your drives are empty or that there is nothing on them you want to keep. The moment you put them inside the unit it is going to format them. It claims some hot swap ability and that it will auto rebuild the RAID/mirror that it boots to on default. It hasn't been my experience but to be fair I basically had to get on and search every single area of settings to see what I was and was not doing (and am getting ahead of myself) The unit goes through a setup wizard, makes you choose a strong password, asks a couple of questions and you are off. Access to it requires that you map a network drive. Clicking on the icon that shows in "network" just takes you to setup page. On default the unit will make you pick a "strong" password and will refuse anything it deems to weak. I utilize an easy password within my LAN (not the log in) that all the shared media folders utilize. I went through the settings and changed what needed to be done in order for it to allow me to set the password I wanted. Setting no password will not work with Windows (as it wants the password). After I got that set and what I thought was fixed...I kept having issues with the NAS logging me out. Right in the middle of access it would be asking me to re-enter credentials that were already saved within Windows. I had to do delete that profile entirely, set it back up again, and finally got that issue resolved. After that I had an issue where once one user was connected others could not connect, would show a "forbidden" message. Finally after several days of asking around, reading each individual setting, changing power settings and Wake On LAN settings I got everything working the way I intended in the first place. As I mention earlier in the review once you put a drive in, even if it's already formatted to the type this unit wants, it formats it. It's default setup is a mirror so one of the drives is being actively written to and then copied to the other. This sounds all fine and secure....well... When I put my first two 4TB drives in the unit erased them, bye bye movie collection. Fine, had it backed up properly. I let the unit do it's format and seemingly am ready to go. The unit is making hella noise and come to find that one of the drives is on it's way out, must have bumped it too hard. The information was already written back to the drives. I take out the bad drive, install a backup and exactly same model drive I had on hand expecting it to mirror, like it said. Nope. Had to rebuild the data a THIRD time. So here, to me, is the catch. Supposedly it's "mirroring" your data. Supposedly it will auto rebuild a swapped disk. It does so in it's little proprietary Linux style format. Nothing other than devices like this can read it. It's worthless to a Windows computer outside this housing....and it DIDN'T auto rebuild. You get this warm and fuzzy thinking you are buying a unit that is backing up and mirroring your data and in reality you are trapping information in a format that won't mean squat to anything else. IF a disk fails it is IMPERATIVE that you back that data up as a precaution before inserting the new disk it's (supposed to) rebuild for you. Well, what if you don't HAVE space anywhere else, because this was supposed to BE your "safe backup"? IMO it's a cool little unit. I would suggest setting it up as one "striped" drive, because the mirror is a lie like the pie. It works well for simple sharing after you bust your rump to get that functionality as a true LAN and not tied up in all the cloud BS it will try to get you to use. For the price it's ok. There aren't a whole lot of compelling items that compete for what this is. It's workable. Most folks are just "going cloud" and letting it do what it wants. Edit - 2025 Just wanted to say that after many years with the above setup just being static, I upgraded it again with larger HDD and also did a firmware update. It was a game changer. All of the settings that seemed to make no sense were made far easier in the UI and it works as I always hoped it was supposed to. ... show more

Overall a great product to backup your personal data
I have the Synology NAS now for about 3 months. It works well for me. Below I listed some pros and cons for Synology from my personal experience. Pros: - Hard drive installation was easy and straight forward. - Initial software setup was easy. - The Synology website has a lot of information on how to setup your synology. So if you do not know to exactly set things up, just google it and you will find the Synology website with information on it. - Helped me a lot and great work to set this information up and to keep it up to date!! - Great mobile phone app support. You can find a lot of mobile phone apps from Synology which work well together with your device. I for example use DS File to upload the pictures on my phone to the Synology NAS. - You have software apps for Synology for a lot of things (more than I need), which is great! - Great support for Timemachine (MacOS) to backup on the Synology hard drive. Works really well despite a hiccup. One time I needed to kill the time machine user on the Synology device since it had 2 sessions at the same time and couldn't do a backup. Worked fine after killing those sessions from my Synology. - Great build in functionality to make your Synology secure (2 factor authentication, encryption, etc.). - You can access your files from the outside world if you want to. Cons: - The indexing of video and photo files is starting right away when you copy it on the NAS. When you copy large amount of photos/videos on it, it will take most of the CPU time. It takes than minutes to log into you Synology drive, but you can pause the indexing for some time. I really hoped that was a support for scheduled indexing (index between like midnight to 6am), but couldn't find it so far. That is probably my biggest complaint. - Antivirus: Not a bit deal in my mind since the info that gets in the NAS was already virus checked in my computer, but you should know that it's not working very well for the following reasons. The antivirus program from Synology does not always work well. I had to install the first virus definition by hand the first time since the antivirus software never finished updating (found that solution on the website and piecing things from other users together). Now its updating just fine most of the time. The scan (according to the antivirus logs) takes from like 2-16 hours for me with my data just being like 400GB (no idea what the virus scanner is actually doing), but it doesn't matter to me when it is done. General caution: - If you never worked with a NAS before I strongly recommend you read up on good practices how to make it as secure as possible. I believe Synology provides that information as well. - Installing this device and setting it up the way I wanted to took me some time. So expect to spend some hours to set it up before considering making it accessible from outside your home network. All in all a great product. The few things I do not like are small compared to the functionality provided by Synology. I think they did a great job with this device! ... show more

Nice Little Mini-NAS, Tech-Savvy Users Only
So this is a low-end, "consumer-level" NAS from a company that mainly makes far more expensive systems for large commercial users. That is both a strength and a weakness of this product. They have made some efforts to streamline the install, but they really haven't completely reworked everything to make it completely idiot-proof or easily accessible for people with limited IT skills. Instead, they basically give you most of the same administrative tools an IT pro would need and cut you loose. There is a web interface and it is not crazy complicated, given that a NAS is basically just a hard drive that is connected to your network, but the initial learning curve is a bit steep, even for somebody who is reasonably tech savvy. You start by taking the thing apart so you can install the hard drives yourself, using a screw driver. You then want to set up a static address for the thing on your network, which means going into your router settings. For all but the most basic needs, you will likely also need to forward some ports. If any of that sounds scary, then just stop right now, this product is not for you. Just pay somebody like Google Drive or Drop Box to store your stuff in the cloud for you and forget about a home NAS. But if that doesn't terrify you, what you eventually get is something that is really pretty useful for storing and accessing your documents, photos, videos etc. You can log into the NAS remotely through their secure portal and download stuff from your home network or push stuff up to it. And it can even stream your media to your phone, tablet, Roku box etc. as long as the media involved is fairly undemanding. This thing doesn't have the horsepower to handle like 4k video streaming, but it will generally stream 1080p MP4 just fine using its own, somewhat limited, proprietary media server. If you are doing high-end video editing or whatever this isn't the NAS for you obviously, but for people with more basic needs, it should be fine. If you are reasonably tech-savvy, all of this stuff is ultimately not wildly complicated, but they definitely don't hold your hand at all, either. You will inevitably be doing some swearing and some searches on Google for "how do I..." Where this device truly comes into its own is that the administrative tools are incredibly extensive and there is a whole slew of surprisingly advanced stuff you can do with it. For example, do you want it to sync to another Synology NAS off-site so you will always have a current, off-site backup? No problem. In fact, there are probably at least a half a dozen ways to run local, remote or cloud based backups of the files on your NAS, and the configuration options are really astonishing. You can give different users their own private spaces, given them shared spaces and the like. So basically, everything you'd need to run a small or mid-sized office is still here in this consumer grade device. What don't I like? Most home users want this thing for a relatively simple and discrete set of tasks, and it is probably going to be sitting idle 23+ hrs a day. So most of the time you want the drive spun down and the thing not being a wasteful power vampire. You need to be careful what applications you install if you want it to idle, certain apps, most critically Plex, tend to keep the thing fully on and spun up all the time. So keep your install lean and stay away from the 3rd party apps like Plex if you want it to actually idle down when you aren't using it. I would rate the noise it makes as reasonable/modest. It probably could benefit from additional sound insulation if you want to put it in like a bedroom. There is at least a setting to turn off the blinking lights, but it is basically a small fan and some hard drives in a plastic box with a bunch of air holes that you can't cover up. That's not a recipe for dead silence. I didn't find it overly obnoxious, but I also decided I didn't want it in the same room as either my home office or my home theater. So I put it in a closet so I wouldn't need to hear it at all. If you have a lot of old, legacy video in like .avi format, expect to spend a fair bit of time with Handbrake, as the "DS Video" application they provide for streaming video through the NAS does not have anything like VLC-levels of support for legacy video codecs. I found that you really want everything you stream over this device in MP4. Nobody is going to be running a private Netflix with this little thing and its dinky memory/processor, but it would be nice not have to re-rip all your old home movies and such to a modern codec just to play them through your TV with their software. UPDATE: I still like this thing as a way to get some aspects of an enterprise-grade NAS in a very cheap package, but understand that it is for fairly undemanding use only. It generally handles a single, 1080p stream with ease, but if you have multiple people hitting it at once or are uploading and downloading a bunch of files to it at the same time, you will notice it bogging down a bit. My sense is that the processor and memory are scaled to the premise that only one or two people are going to be using it at a time, and so once you start to pile a bunch of concurrent tasks onto it, you will wish you had spent more money for a NAS with more powerful internals. So a big family or small office might want to consider spending a bit more and moving up to something more powerful than this. ... show more

220J and 420J Very Fast, Easy Setup, Reliable and Quiet
Review Image by rkruz
Review Image by rkruz
Since Amazon groups the 220J and the 420J together I cannot review the 420j separately so I am revising my 220J review to include the 420J. I got the 420j 15 months after the 220j and as expected the 420j is also excellent. I actually got a great bargain on the 420j from the Amazon Warehouse for a returned items whose package indistinguishable from new. I use the Synology 220J and 420j in a very simple way, to set it as the destination for the download of torrent files, backups, and for storing other large files I don't want to use up space on my solid-state drive. The PC is a Windows 10 and wired to a 1G LAN. Both NAS's are cabled directly to the 1G port of a Netgear r6700V3 router. AS long as I used wired (not wireless) the connection to both NAS is very fast even approaching the data limit of the 1G Ethernet interface. See the attached graph showing a speed test to both NASs from my laptop to each of the Synology units. Very fast indeed at the max capability of the 1Gb network. THE GOOD: -- EASY TO INSTALL: Doing very little more than installing the hard drives, letting the units run their initial installation, and then setting up a shared folder, and was quickly able to see the NAS's from both of my Windows 10 laptops. Very little to do to start using the NAS. -- FAST TORRENT SAVES: Saving torrent files over an ethernet cabled connection the speed was as fast as the torrent downloads themselves. Very pleased. -- GOOD STREAMING: I was able to play a 4K video from the 220J over the 1G LAN to an NVIDIA Shield with excellent results. No pausing or jerkiness. The 220j and the 1G LAN were not at all stressed by this. -- GOOD SUPPORT: I was impressed with the tech support. They were always available and reasonably knowledgeable but were unable to offer a reason for the slow torrents. -- QUIET: The fan in both units is surprisingly quiet and with adjustable speed. -- FAST FILE TRANSFER: When I copy a file from the PC (where Ive saved a torrented file) to the file it's very fast. I see speeds of 115 MBps on a 1G LAN. See the attached speed test for both units. -- VERY RELIABLE: Over 15 months of use the 220j NAS has been available 100% of the time, connecting to the network and operating over its web-based interface. I've had the 420j for only a week but I expect the same remarkable reliability from it. -- CAREFUL WITH DRIVE SELECTION: I only say this because I initially installed some good value Hitachi 4TB drives that turned out to be noisy as heck. They made a loud thumping sound as the heads moved, so much so I had to change the location of the 220j to another room where I would not hear it. -- QUIET HARD DRIVES: For the 420J I used 4ea Seagate Barracuda 4TB drives and I don't hear them at all. In fact, the fan is louder than any noise the drives make. The Bad: Not a thing. CONCLUSION: Both the 420j and the 220j do a lot of things and is probably much more sophisticated than I need and for the simple task of saving files from my PC over a LAN, but it's a great easy to setup and a supremely reliable solution. ... show more

Reliable
I bought this synology NAS drive to replace a synology drive I had installed fifteen years ago. I use the drive as a central data repository for my home network, storing photos, music and laptop backups. My old one proved very reliable but I figured the disc drive, running 24/7 were getting to the end of their life. In fact, about five years ago I bought another manufacturers NAS drive to use. But I found it unreliable, repeatedly going off line and not being accessible when I needed it. This would be corrected by powering down the NAS and restarting it, which typically took ten minutes. Meanwhile my synology NAS just kept going alongside it. This new NAS seemed so unreliable in comparison I never took the original synology NAS out of service and they ran side by side for five years while I recovered from the financial outlay. I bought this new synology NAS six months ago and set it up. I took down my interim and unreliable NAS but kept my old synology NAS running alongside this one. I was impressed that the synology shell on my laptop found both NAS. I found the graphic interface to be familiar and as intuitive as ever. I was able to do a NAS to NAS transfer of all my photos fast. I had a cleaned up music collection on a USB drive and was able to plug that into the rear of the new NAS for a fast transfer. And it was easy to setup automatic backups for my laptop. And most important, the NAS appears as reliably available as my original one. After about two months I finally retired the 15 year old NAS and just have this one on my network. The interim third party one I had tried would have hung at least three times in that two month period. This new synology NAS, not once, showing equal accessibility as it’s one and a half decades old brother. I’m six months in now and have no issues with this product, my experience with this has been excellent. Occasionally Windows explorer will show a mapped folder on the drive as inaccessible, but as soon as I click on the folder it becomes accessible and opens. I think this might be a quirk of Windows. I will update my review in 2038, when this one turns 15. ... show more

This is a great little NAS!

Review Image by Zach S.
This is a great little NAS! I went looking for a 2 bay NAS unit after my most recent update on Unraid for my main Tower server Time Machine stopped working. Whatever I did, I could never get it to work. After asking on the forums, they said it's a common issue. I took out 2 5TB empty drives (bought in 2014!) that weren't being used for anything and planned to use them here. I eventually settled on the DS220j unit over the DS220+. I couldn't justify spending the extra money for features I didn't need since I still had my server for everything else. The one feature I liked on the + was USB flash drive button copy and front input, but couldn't justify spending the money just for that. When I got it, assembly was super easy. The case didn't have any screws in it yet, so you just pulled it apart and the drives to the bays went right in. Used the supplied screws to secure them in their bays, close it up and you're off and running. Setup was super easy. The installation automatically sets you up for their SHR Raid. You do have the option to change that if you want later if you want but I left in that cause I figured why not. It set you up with default share folders, which I didn't like the names of. I wanted to delete/rename some of them and had to disable some of the default apps to do so. Wished they'd give you the option if you rename it it'd update in those apps also. I just left them disabled since I don't need em anyway. First thing to do was setup Time Machine. Digging around found instructions and that was fairly easy to setup. Created 2 users, was able to set size limits in their profiles. Backed up both Macs to the one folder and has been working great since. Next I setup a Plex server to test out. Direct Play worked fine streaming the movie from my server, but Transcoding forget about it. If all your clients in your home can Direct Play and that's all you care about, you can prob get away with it. But if you want Transcoding and more features, get the + or one of the other '20 models with more drive bays. You'll thank me later. The next thing I did was buy a USB extension cable and got USB Copy going. I needed to buy the exFAT Access app to unlock that but once I did it worked great. Set it up so if I plug it in, it'll automatically copy the drive when I do and eject when it's done. The cable works great to give me front port access too. Haven't done much else besides those 3 things, but there's a lot more you can. So if you're looking for a simple file sharing 2 bay NAS this is it! If you want to do more things like install Docker suppoort, Transcoding Plex (please get more then 2 bays!) and other things look at the other '20 Synology models. But if what I described here is all you need, go for it! ... show more

Fantastic
Review Image by Adam
Every now and then I run across a well designed product which completely fulfills its purpose. This is one of those products. These things really impressed me: - Small form factor case with a clean design - Simple setup (I was initially worried about the privacy policies and online access but was able to easily opt out) - Internal layout well designed, it was really easy to disassemble and install drives. - The interface... really really impressed with how smooth the interface works via the browser. Lots of utilities and easy to read resource monitors. Good array of additional packages which can be added (could run my own web server, python, and Java apps) - Performance: I picked up two Seagate Barracuda 2TB drives and performance over the network was within my expectations for these drives (around 100MB/s sustained writes). There’s benchmarks of SSD’s pushing gigabit LAN connections to the max which is pretty impressive. - Resource usage: while a 1.4 GHz quad core with 512MB of RAM doesn’t seem like a lot, performance seems solid and resource utilization of the unit was pretty low during transfers Cons: - The unit I received had a noisy fan but given the the simple design, replacement should be easy so no real concern there. Overall this is a solid and well thought out product that I’d highly recommend to anyone looking for a simple 2 drive NAS. ... show more

Perfect for the home or small office
Especially considering the price of this NAS, it is great. It's perfect for the home or small office. It allows an ordinary person to setup his or her own cloud, providing backup and sync services. There are many other uses which I haven't even had a chance to explore. Now that Amazon does not allow us to upload music that we already own, using this as a music server is a perfect fit. Every day we hear about another company getting hacked and exposing customer confidential information. There is definitely a growing niche for small NAS units like this. The initial installation was pretty simple ... no issues. I installed (2) IronWolf 8TB drives. The 4-core 1.4 GHz CPU seems to have enough "muscle" to handle the task. My initial impression is that the hardware is very good, and it physically looks nice. However, I believe the documentation assumes a level of IT knowledge that the buyer of such a small NAS may not possess. I am not new to computers, but am not an IT person per se. It seemed like the documentation was lacking in detail and assumed that the user understood IT terminology. I looked for a "dummies" book specific to Synology but came up short. This slowed me down a bit, but I persisted and was able to successfully sync two computers in our house and have begun using Audio Station. Also, the Synology tech support group was very helpful. Overall I would give this unit a "thumbs up". ... show more
