The TowerRAID TR4MP is a compact RAID tower utilizing the latest SATA II port multiplier technology, where one single eSATA cable connects to four 3Gpps SATA II hard drives. Bundled with a high performance RAID controller card RR622, its RAID 5 performance is capable of reaching over 200MB/s. Online expansion is a feature included in the controller card allowing the RAID to 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 tray-less TR4MP allows instant setup by simply inserting the hard drives after opening the protective ventilating cover. The included dual-port eSATA 6Gb/s PCIe 2.0 x1 RAID controller card allows the connection of up to two TR4MP units (up to 8 hard drives) using only two cables, while all drives could be configured into a single or multiple RAID arrays, providing over 200MB/s in performance.
Note: Sans Digital recommends the use of enterprise hard drives when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance.
