Summary: This is the second Synology storage device I've purchased and I'm still using the first one. I did a lot of research before buying the first one and I definitely made the right choice. An exceptional company that makes great products, at great prices, stands behind them and answers emails and the phone to address any questions you have. They have a very knowledgably user base and the User Forum has a lot of great information. You will not be disappointed.
Summary: I work in a 25 user office and we needed more storage but I didn't just want to buy something that added storage I wanted something that would add more usability. So far this unit has been very good for storage shares which we use for Windows clients and very good with WedDAV over HTTPS for iOS/Android usage. I combined this product with the Western Digital RE4 drives and it has had no issues so far.
Summary: It is my second RS2212+ and fifth Synology NAS RAID. So far, it is the best, most manageable, reliable and easy to use network storage. All models, from small 4-disk to large 10-disc devices use the same OS, based on busybox linux distribution. Software designers built good GUI, added plenty of useful applications, and overall, made a very good storage device.
