TowerRAID series debuts
Sans Digital has introduced its new TowerRAID series, which includes the TR4M SATA to JBOD enclosure and the TR4U SATA to USB 2.0 JBOD / Spanning enclosure. The new TowerRAID TR4M is a compact 4-bay tower utilizing an SATA II port multiplier feature, where one single eSATA cable connects to four 3Gbps SATA II hard drives. This unit comes with a 2-port eSATA PCIe card (HA-SAN-2ESPCIE) at no additional cost, which allows the connection between two TR4M units (up to 8 hard drives) using only two cables. It supports RAID 0, 1, 0+1, 5, 5+spare, spanning and JBOD. It is priced at $360. The TowerRAID TR4U is a selectable hardware JBOD or spanning enclosure that utilizes the USB 2.0 interface for storage expansion. The JBOD mode allows the computer to see each individual hard drive, while the spanning mode presents multiple hard drives as one combined drive. Various combinations of JBOD and spanning mode can be used. Both units feature hard drive bay cover, cable-less backplane, and tray-free swappable design. It carries a price of $250.
