TowerRAID TR4MHA - 4 Bay SATA RAID 0/1/10/5/JBOD Performance Bundle (Silver)


The TowerRAID TR4MHA is a compact RAID tower utilizing the latest SATA II port multiplier feature, where one single eSATA cable connects to four 3Gpps SATA II hard drives. Bundled with a high performance RAID controller card RR2314, its RAID 5 performance is capable of reaching over 200MB/s. Online expansion is a feature included in the controller card so that RAID could 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 allows instant setup by simply inserting the hard drives after opening the protective ventilating cover. The included 4-port eSATA PCIe x4 controller card allows the connection of up to four TR4M units (up to 16 hard drives) using only four cables, while all drives could be configured into a single or multiple RAID arrays, providing over 600MB/s in performance.
