The TowerRAID TR8UT+B is a 8-bay hardware RAID 00/30/50 storage tower that utilizes high performance USB 3.0 and eSATA interfaces to provide over 200MB/s in performance. The included USB 3.0 is backwards compatible with widely available USB 2.0 ports, which is a convenient feature when both USB 3.0 and eSATA connections are unavailable. With built-in RAID 00, 30, 50 and JBOD, the TR8UT+B provides hardware RAID redundancy protection against hard drive failures. The RAID engine is embedded within the enclosure and performs all RAID parity calculation to reduce CPU utilization from the host PC. RAID controller cards are unnecessary.
