Sonnet Technologies has announced a desktop RAID system, the Fusion D400QR5, along with its rackmount counterpart, the R400QR5. Both devices build upon the companyĆs previously released D400Q and R400Q four-bay systems, adding a RAID 5 controller for improved balance between data protection and usable capacity. Both systems support eSATA, FireWire 800 and 400, and USB 2.0 interfaces, while enabling users to select a preferred RAID mode or configure each individual drive.
