Radion has introduced several GearRAID quad-bay data storage subsystems with enhanced data protection when the drives are configured as a RAID 5 array. The storage devices integrate an Oxford936QSE chipset, enabling four 2TB drives to be configured as a RAID 5 array with a maximum of 6TB of overall storage space. The drives are capable of automatically backing-up data, while one hard drive can fail without any loss of data. Each storage system also supports eSATA, 1394b and USB 2.0 host interfaces.
