With the Synology DS1819+, you'll have an NAS at home or at the office that can handle multiple demanding network tasks simultaneously. The 2.1GHz Quad-Core processor, the separate encryption processor, and the 4GB RAM allow you to work quickly and securely. This business NAS has no problems simultaneously streaming 4K videos, storing extensive photo libraries, and making various backups. In addition, this NAS has enough room for expansion, as you can install up to 8 internal hard drives in a RAID array. On top of that, the Synology DSM software lets you control your NAS' performance, update the firmware, manage your media collection, and install all kinds of extra apps, such as Plex, used to stream media.
