Sans Digital 4-Bay eSATA RAID 0/1/10/5/JBOD Tower Storage Enclosure w/ 6G PCIe Card TR4M+B (Black)

The TowerRAID TR4M+B is a compact RAID tower utilizing the latest SATA II port multiplier technology, where one single eSATA cable connects to four 3Gbps SATA II hard drives. Bundled with a high performance RAID controller card RR622, its RAID 5 performance is capable of reaching over 200MBps. Online expansion is included in the controller card so that RAID can be expanded without the need to recreate the storage space or erase the existing data. Advanced monitoring functions include real time hard drives health status and e-mail notification for critical events.

Designed with easy installation in mind, the trayless TR4M+B allows instant setup by simply inserting the hard drives after opening the protective ventilating cover. The included dual-port eSATA 6GBps PCIe 2.0 x1 RAID controller card allows the connection of up to two TR4M+B units (up to eight hard drives) using only two cables, while all drives can be configured into single or multiple RAID arrays, providing over 200MBps in performance.
