Sans Digital TowerRAID TR5UT+B - 5 Bay USB 3.0/eSATA Hardware RAID 5 Tower with 6G PCIe 2.0 HBA (Black)

The TowerRAID TR5UT+B is a 5-bay hardware RAID 5 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 0, 1, 10, 3, 5 with hot-spare and JBOD, the TR5UT+B provides hardware RAID redundancy protection against hard drive failures. A brand new RAID mode, CLONE or N-Way Mirror, is also introduced to replicate the saved data throughout each installed hard drive. 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.
