Well-suited for large-scale enterprises with demanding business applications, the RackStation RS3618xs 12-Bay NAS Server from Synology helps simplify data management, optimizes virtualization environments, and rapidly expands storage capacities. This unit has 12 drive bays, each of which natively supports 3.5″ SATA hard drives, as well as 2.5″ SATA hard drives and SSDs. Should users need to expand the overall capacity of their RS3618xs, the optional RX1217/RX1217RP expansion units offer an additional 12 drive bays, and two of these units are supported via integrated expansion ports.
