I replaced an older Netgear 4 bay NAS with this one and the Synology is far superior in most ways. I did add the two NVMe SSDs for read and write cache and upgraded the memory to 8GB. 1) My disks and the unit run cooler. 2) The unit is whisper quiet while keeping everything cool. 3) It is much faster as far as responsiveness, responds like an internal disk or SSD when looking at files etc. (I'm sure the 500GB of SSD cache has a lot to do with that) 4) Using the duel Gbit interfaces in bonded mode I am able to sustain ~ 230 MB/sec write speeds (115 MB/sec from two different systems doing simultaneous backups. 5) User interface is good and easy to use 6) Lots of built in and downloadable apps available for most anything you want to do. 7) Built the 4 disk 56TB RAID 5 and optimized it in 20 hours which is much faster than my old unit with the same disks. 8) CPU seems to have plenty of power for running the extra apps. My CPU utilization is about 26% under heavy dual system backups. 9) The Hyperbackup app works well and was fairly easy to setup to use rsync to a TrueNAS system. Overall I am quite happy with the DS920+ and would recommend it to anyone looking for a great home or home office NAS

My last NAS was a Synology 918+ and I was very happy with it. I decided to buy another NAS, and I thought I would try a QNAP as it has 2.5 Gb networking, HDMI out, and a faster processor than the 920+ for about the same price. I have been developing Linux software for 25+ years, and even though I had read the QNAP software was less straightforward to use than Synology, I was sure I could handle it. After a week of battling with it’s poorly designed and tremendously difficult to use software, I returned it and bought the 920+. Synology has always provided a polished user interface, and DSM 7 is even better than the DSM 6 I have been using. Everything is well thought out, easy to use, and for Soho applications this NAS will do everything you need. While I do wish Synology offered faster networking with its Soho class of NAS than the 2x 1GBe ports, the software more than makes up for it. One more thing in Synology‘s favor is support. My 920+ works great, but my 918+ failed to boot about a year in after a lightning strike that also took out my LG OLED :( I called Synology and they had a replacement unit to me in two days, even before I returned the failed one. That kind of support provides a lot of faith in the company. This unit is easy to set up, easy to configure, easy to use. It will do everything from Nas storage to surveillance to VPN to containerized applications. Mac Time Machine and Windows incremental backup are easy to set up, and if you have a computer failure restores are fast and reliable. You can also back up with rsync or iSCSI. It supports shares via SMB, Mac AFP, and NFS, all easy to configure and use. Pretty much everything you could ask for in a Soho Nas is here at a great price. Another advantage is SHR or Synology Hybrid RAID. Since this is a secondary unit for me I only required protection against a single drive failure. In this mode, SHR makes much better use of mixed size drives than you get with standard RAID 5. Having the latest and greatest hardware is attractive, but it’s useless if the software is difficult to use or the support is less than ideal. I am extremely happy with both of my Synology NAS boxes.

Hi Everyone, I have had mine for a few weeks now and I consider myself somewhat of a heavy user and this seems to hold up very well, I work with photography and I moved roughly 40000 images over to the NAS and I have Synology Moments app running and the AI facial recognition is simply amazing and really help me find some order to my life :) I must say the NAS did work hard to catalog all those pictures and the CPU was averaging around 99%. Even though with the high CPU usage I was login and use the system, for the other users that I have created they didn't really notice the overhead on the CPU during this time ( Which took around 2 days for the AI to do it's thing) However I also have the 220J and when I tried adding that number of images, we had to wait for the cataloging to complete before I could do anything. Being able to access my files and photos remotely thanks to Synology's quickconnect/Drive options is simply fantastic, This is also a great option to create backups for your phone/laptop whether you are away or at home for the whole family or colleges. Synology has a great SHR Raid, (Synology Hybrid RAID), thanks to this RAID I was able to expanded my volume without having to rebuild the array and still have 1 drive fault tolerance and zero down time! I haven't had any trouble with mine thus far, it was really easy to setup and connect, it was as simple as going to a find.synology.com from your PC/laptop which is on the same network and either create a synology account or sign into an existing account. I will be looking at the Synology 420+ in the future and setting up a remote/ off site backup and open a lot more possibilities. ( I'll circle back here in a few months or so to add any additional comments. My primarily uses are at the moment are: Phone/ laptop backup and shares (Synology Drive) photography file managing and organization, It's more than a giant hard drive. I also have DNS (Domain Naming service) running on it for the network. Docker, which allows you the ability to build virtual machines within your NAS. (pretty useful) If you are thinking of purchasing this Synology 920+ I can assure you, this a great NAS with enough options to upgrade in the future. As it supports the additional drive unit which can be attached. ( If you go with additional expansion bays, I suggest creating separate volumes for each unit rather than creating 1 volume across both units.) you are also able to upgrade the memory to 8GB and add SSD caching to further improve the performance. If you have any question, please ask. Thank you

Yes, this NAS can do a lot more than just being a Plex server and a file server, but that's all I'm using at this moment. I will update this review if I start adding significantly more features to the NAS. First of all, even with a Celeron processor, it has no problems transcoding 4K video in real time for display on other devices through Plex. When transcoding 4K to my iPhone XR, the CPU usage was around 5%. That means this little NAS could likely handle multiple 4K transcoding streams at once... probably limited more by network bandwidth than CPU power. This is likely because this is a very recent Celeron that just came out in the 4th quarter of 2019. The one thing that really surprised me was the quality of its user interface. It is web-based, but if you put it in full screen in your browser, it looks like (and works like) Linux. They really put a lot of effort into the user interface! Configuring things in the Control Panel has "basic" and "advanced" options, so even beginner users won't be overwhelmed. It's one-click easy to add new "packages" (add-in programs, essentially) to your NAS. Adding Plex is a single click and you're off. I enabled SSH to better communicate with my Linux servers and was surprised that the software didn't automatically create a home directory for my user account. It's easy to resolve, but it was an oversight. A very small one., and about the only thing that didn't work absolutely perfectly right out of the box. Migrating files from my failing 5TB external drive (NTFS formatted) to the NAS was as easy as plugging the drive into the front USB port. The user interface picked it up immediately, and I was able to use the File Station to move the files exactly where I wanted them. I purchased my DS920+ with two 8TB Seagate Iron Wolf NAS drives, with the thought that I can add up to two more in the future. When I need the storage, I will update this review and talk about how easy/difficult it was. Note that the Iron Wolf drives "tick" every 5 seconds or so, so if you are using this NAS in a bedroom, it might be annoying to you. My NAS is in my closet with my other networking equipment so I don't notice the noise.

I purchased this NAS to be able to access my files from any of my computers and have all the files in one place safe and backed up so no matter what computer I use I am always accessing the same file and it is always up to date. There is a bit of a learning curve so if you are new to Network attached storage you will have to invest some time for the setup. That being said I would highly recommend a Synology NAS. The software is well written and I did not run into any glitches. The unit I ordered did not come with any HDD’s so I purchased four Seagate IronWolf 4TB HDD’s. I upgraded with a 4GB Synology memory module for the ram, and two Samsung 970 Plus 1TB M.2 NVMe SSD’s for the Cache. The unit will work fine without the upgrades but will work better with them. The Synology website has a page to show what upgrades are compatible with the unit you purchased, and are supported by Synology. I set up my HDD’s with SHR2 so I can lose up to two HDD’s at one time and my Data will still be safe. I also set up my NAS system so it will back up to a WD Elements backup drive automatically at night. If you are new to NAS units there are some great YouTube videos to get you started. I would recommend doing a YouTube search for sinology NAS and SpaceRex His Vids are clear and to the point. He has everything from getting started to adding cache, and making backups. Plus: • This NAS can do far more than I would ever need it to. (Research the many options) • Everything works just as I wanted it to, all my files are finally in one place and safe from HDD failure. • Front LED’s brightness is adjustable. • Fan speed is adjustable • Easily upgradable to larger HDD’s • Lots of great how to videos and info online Minus: • If you use mechanical HDD’s There may be a small lag while the drives are spinning up after being in sleep mode. (The optional cache can help with that) • Newbs will need to invest some time to learn the system, (It’s not that hard and well worth the investment in time). I did a lot of research before deciding on Synology and I am very happy with my choice. My personal opinion is that the Synology hybrid raid system, SHR, and SHR2 is superior to that of a regular raid system and I can always easily upgrade to larger HDD’s down the road if my needs change. I would definitely purchase this again.

I've used a DS212 for years so I was no stranger to Diskstation 6, which was pretty awesome in every way except expandability and speed. This was my shot to improve both. Within days of installing mine, it upgraded to DS7 which was even better. The UI on the 212 was functional, but lagged into oblivion, The 920 is fast enough on the same network with the same client-side interface (web, browser) that it was easy to forget that you were on a web UI at all. It's SLICK! FOR MY USE, I decided a tricked out 920+ was better than waiting for the 921/922/923.. (Mine is a prosumer network with machines dwarving humans.) I added RAM for VMs and NVMe write caching, well, because I did. $100USD off for Prime Day made it even easier. That gave me a set of known restrictions on aftermarket HD, RAM, and NVMe.. While they take great care to provide everything you need in that pretty web interface, you can also turn on a perfectly functional Linux shell if you're into such things. It's a relatively plain old Linux kernel, now offering up BTRFS which allows nice things like snapshots, previously unavailable. Time Machine images, long a problem for NAS vendors, are possible, but they aren't bulletproof. I have five machines that are flawless and one that keeps needing rebuilt from scratch and I can't figure out the difference why. Others in various NAS forums report similar ghosts in their Synology attics. Buying this on an 8-10 year depreciation schedule, I'm bummed that there just isn't a viable 2.5GBps upgrade path. It's pretty disappointing that there isn't an SFP port on these things so we can replace a couple of $10 1Gbps copper ports for $30 2.5Gbps or $40 5.0 Gbps. That capped speed is my biggest regret/restriction on this product. I've found the synology line and this device in particular handy as: A) A place for Time Machines to live.. B) shared NFS/AFS filestore that's just crazy fast. C) a place for shared apps via Docker to spin up internal applications to share with, um, myself. LAMP instances, Git servers, etc. are all just dead easy. D) (soon) a way for all of the above to be backed up remotely still. E) An easy way to have x86 Linux available house-wide I've made the investment in time to make it all work well and the investment in hardware that I (mostly) have an upgrade path forward. It's not likely that I'll be bummed out by the 2032 equivalent of an RS2121 or HD6500 or whatever. I'm not going to outgrow this product family, so my investment in time won't be totally lost.

I work as a technician for a number of clients, both personal and in small business. One of my clients had ongoing issues replacing their old server (they didn't know what they were doing and got themselves into trouble, which is where I came in). After a day or two of looking at their "new server" and then what they needed (basically, just file storage/sharing), I thought a NAS would meet their needs. I already owned (personally) a small NAS, but I hated it, so I went shopping for something of higher quality. I hit upon Synology as the obvious choice in this range, and while the pricing was higher than "what you could get a NAS for", it was still far less expensive than my client's alternatives. The hardware is easy to set up, even if you're adding RAM or cache disks, as long as you're comfortable doing some basic hardware-type stuff. Adding disks is easier than changing disks in a desktop (but 2.5 drives will need an adapter). Adding RAM is a little bit easier than would be in a laptop (you have to remove some of the disks, but don't need tools). Adding cache disks is similar to adding RAM to a laptop-- flip it over, screwdriver, insert, ya done. IMPORTANT: if you want write-caching, you HAVE to use a second cache disk. For whatever reason, you can't split a cache volume for read/write. If you have just one disk, you can only use Read caching. I wish I had known this ahead of time, or I wouldn't have gotten as large a cache volume, though it is serving me pretty well. Once booted up and online, though, is when a world of wonder begins. The system has feature upon feature upon feature, allowing it to replace far more than just a file server, at no extra cost. There is a package system where you can download optional packages, including things like: Video streaming service (2 kinds!), audio server (complete with mobile app to stream your own music to your phone), Cloud Storage (your own personal Dropbox), system backup (that is, software to backup systems on your network to the NAS) and ways to back up the NAS to elsewhere, IP camera software (with a few licenses included), mail server, group calendar, WebDAV connections, and so much other stuff. You could certainly get all of these features by building your own NAS and using all the open source software out there, but for the amount of effort and ease-of-use here, it's no contest. One thing I was very impressed by with the initial configuration is that Synology have their own type of RAID setup called (SHR-- Synology Hybrid RAID). It has the data-protection and speed benefits of a RAID, but allows it to be used across completely dissimilar disks, as well as adding disks to the same SHR later on (and the volume checking and expansion happens while the NAS is still working)-- this definitely lowers the commitment anxiety to setting up a new disk array. It also has a USB 3.0 port in the front, and you can add external disks that can be mounted and shared seamlessly. The system is highly configurable through the UI, but you can also open a Terminal, or use SSH (if enabled). The task scheduling system can call bash scripts, also. This makes me feel like the UI is a convenience, not a required hindrance. That said, though, the UI is ridiculously thorough.

After one week, my impression is very positive. I'm very happy with my purchase, which was the DS920+. My goal was to 1) setup a media server and 2) setup a backup solution. This box achieves both of my goals very well. Highlights: - Super easy setup - Powerful UI that's easy to use - Package center (their app store) is convenient - Seems to just work (so far) Lowlights: - I wish it were cheaper (of course) - File system is a bit glitchy when using rsync Disclaimer: I'm a tech professional; not versed in IT specifically, but I'm pretty comfortable with tech Based on reading others' reviews, I was nervous about the setup. However, it turned out to be super easy and straightforward once I gave it a shot. I was able to get it going pretty quickly, then it was just a matter of waiting for the disks to be setup and copying my data over. The USB connection made it easy to do that. I really like the UI they've built. The best part is the Package Center, which makes a lot of things available with a few clicks. For example, just search for Plex, hit "install", then just set it up on a shared folder. Got it up and running very quickly. Overall, pretty happy with this box. I would highly recommended it. Not sure why others had so much trouble, it was pretty straightforward for me.
