ESFWBU2SATA525QR6 is most cost-effective SATA II disk drive RAID subsystem with completely integrated high performance and data protection capabilities. ESFWBU2SATA525QR6 takes full advantage of high-speed 1394/USB serial bus and Serial ATA Bus allowing for multi-user and multitasking performance. ESFWBU2SATA525QR6 delivers the performance required for servers and I/O demanding applications such as Video-On-Demand, database servers, workstations, high-end desktops, and image systems. ESFWBU2SATA525QR6 allows two HDD failure without impact on the existing data and failed drive rebuild is transparent to the host. Environmental information is accessible either via the control panel/serial port or Ethernet port.
