Expensive but fantastic if you don't mind the cost!
I was previously using the WD My Cloud EX2 Ultra NAS (https://smile.amazon.com/Cloud-Ultra-Network-Attached-Storage/dp/B01AWH05KK/) with 2 x 8 TB WD Red SATA drives in RAID 1 (mirrored disks). While that was cheap, it was not meeting my performance expectations. I have a ton of content (Audio, Video, Pics) stored on the WD NAS and it would struggle when I try to fast forward/backward and/or have multiple end points try to stream from it (like 2 TVs simultaneously). I realized I needed something more beefier and went with the more expensive DS720+ Pros: - The sheer number of things one can do with this thing is amazing. If WD was 2 out of 10 (in terms of features and functionality), I would rate the DS720+ a 9.5 out of 10! - I preferred DS720+ (over the cheaper DS220+) as it has the option to upgrade RAM/memory and NVME SSD for caching. This will keep me future proof for a long time (I hope!) - The UI is extremely rich with features and options and one can spend hours figuring/trying things out. I prefer this over the more simplistic solutions that treat people as if they are ignorant and don't know what they are doing. - The number of apps one can try in the Synology ecosystem is huge and most are free! - Had to destroy the data on the 2 X 8 TB WD red drives as Synology doesn't recognize the WD file storage format but that is understandable. Took a backup of my data onto another external drive first and restored it once I reconfigured the drives in the Synology Storage Manager app. The process was slow but it was fine as it was a one time affair (had to copy 5 TB worth of data). - While "Quickconnect" is a great idea to allow access to the NAS data from anywhere on the internet, I don't see the need for that in my use case so I didn't bother to try that out. Don't need another attack vector that I need to worry about! - Added 1 x 16GB RAM DIMM (https://www.amazon.com/gp/product/B07H4XNNXK/) and 2 x 1 TB Samsung NVME SSDs (https://www.amazon.com/dp/B08V83JZH4/) and that really seem to help with buffering and performance in general. The process to do these hardware upgrades was really simple and anyone can do this. I know this configuration (esp. the 16 GB RAM) is unsupported by Synology (check out YT videos for more info) but I didn't see any issues so far. - Like the 2 x 1 GB NIC cards option as one can get more throughput out of the system. Better to setup a static IP for each of the MAC addresses so it is easy to access them over your LAN. - I can probably list a few more positives but the list has been long already! Cons: - Synology only "supports" their own products for upgrade (RAM, NVME). These "products" are extremely expensive as compared to other reputable brands (e.g. Samsung). While I didn't see any issues so far with using non-Synology products for upgrade the NAS so far, it would be nice if they also "certify" other reputable brands. But, that is too much to ask for as it affects their profits! - Warning: running non-Synology products does void your warranty, as per Synology! Unless you are business that is worried about using "certified products" and/or "supported configuration", for regular consumers like us, it shouldn't matter as long as it works :) YMMV though! - Looks like only drive sizes up to 16TB are supported. I am not worried about crossing that limit anytime soon but wanted to call that out in case your storage needs are around that limit Overall, I highly recommend it, if you don't mind paying extra for all the bells and whistles! ... show more

Pro quality at a reasonable price
I love this NAS device. It is designed and built well, and the plethora of software available for it is just amazing. I have used it for some time now, and I have nothing but praise for it.

Worth it!
Works great and is very user friendly. I had a minor issue with tech support but I believe the technician was new. They didn’t quite know the product. This product versus the Synology DS120j: The DS120j (not this product) was great and very functional. The major difference is that it had lower cores and because of that, it can’t run a virtual machine nor handle multiprocessing. That’s pretty much it! Everything else is the same. So for anyone who doesn’t need to run a custom programmed server with high throughput, this is the system for you. The DS720 (this product) has all the functionality of the DS120j plus the extra processing from having more cores. It can handle a virtual machine decently or my custom program as a server. Nothing much more. What they BOTH do well without much of a difference: * host a website is done nicely (if you need a high number of people accessing your website simultaneously, I’m not really confident these two will do) * backups * storage * SSH access * hosting a program * hosting a database * multiple user access (with some variations) * autonomy …. Really… they both do everything very well. The main difference is mostly just the hardware. You’re not really getting a broader range of cutting edge software by getting one over the other. Unless the software absolutely requires multi core functionality (e.g a virtual machine). ... show more

Excellent for Mac Time Machine backups, and media serving
Back in the day I had an Apple Time Capsule for doing Mac Time Machine backups. Then Apple got out of that business, and I went on a search for replacements. First I setup an old MacBook Pro as a server. That worked well, but it had a few disadvantages: It added some clutter to my office (a Mac and external hard drive). It didn't have a RAID drive for data redundancy. And all of the configuration had to be done via the MacBook Pro. This means that hiding it away in a closet wasn't practical. In order to address those issues, I decided to try the Synology DS720+ NAS. I had never used a NAS before, and I was concerned it would be difficult to setup. I'm happy to report it was quite easy. I would say it took me about 5 hours to setup, and learn about its Time Machine and media serving capabilities. It's been up and running flawlessly for about a month now. I have 3 Macs that are backing up to it on a regular basis, and I'm using its Plex server for media sharing. It's all working great, and I never have to mess with it. Also, it's so compact that I have it sitting in a network closet. I have it plugged into a CyberPower UPS that provides it with backup power in case of a power failure. It even communicates with the UPS, and does a controlled shut down in case of a power failure. So yeah, I would definitely recommend this NAS. ... show more
