Scalable Mass Storage With Fast Connectivity
Synology DiskStation DS3622xs+ is a 12-bay tower server NAS for businesses that need large and powerful storage. The DS3622xs+ matches high capacity with strong processing capabilities, making it ideal for business surveillance, virtual machine storage, and video editing. Its storage capacity is easily tripled with two 12-bay DX1222 expansion units. Connectivity, storage, and memory are easily expandable to handle even more demanding workloads. Coupled with a large offering of business applications available for Synology DiskStation Manager (DSM), the DS3622xs+ is much more than a storage device.
