The Synology RS820RP+ is a rackmount NAS with 4 bays, intended for small office. You can attach this NAS to an RKS1317 rack, so your NAS takes up little space and you can install multiple rack mounts. Thanks to the Intel Atom quad core processor, the RS820+ works fast with a high clock speed of 2.1Ghz. The 2GB RAM allow more than 10 people to use the NAS at the same time. If you need to, you can expand the RAM to 18GB. On top of that, link aggregation through 4 network ports creates a higher throughput speed. Thanks to the BTRFS file system, your rack NAS automatically repairs file errors and keeps multiple file versions. With the Synology DSM software, you can also use the NAS for virtualization or as a surveillance center for IP cameras.
