TowerRAID TR4UT+ - 4 Bay USB 3.0 / eSATA Hardware RAID 5 Tower (Silver) (Refurbished, 3 Months Warranty, no controller included)

Refurbished items may contain minor cosmetic damages that do not interfere with the functioning of the product. All refurbished items are burned-in and tested prior to being packaged to ensure maximum reliability.

The TowerRAID TR4UT+ is a 4-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 TR4UTP 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.

To satisfy the need for performance demanding applications, the unit is bundled with a 2-port PCIe 2.0 x1 eSATA controller card with SATA 6.0 Gbps (6G) support (RR622 controller card). PCIe 2.0 is capable of providing twice the bandwidth of PCIe 1.0, allowing over 200MB/s in performance. The unit is also backward compatible with PCIe 1.0 slots to provide eSATA connectivity for computers that do not have built-in eSATA ports. The TR4UTP is the ultimate RAID storage for all storage needs.

Note: Sans Digital recommends the use of enterprise hard drives when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance. For more information on the difference between RAID and desktop hard drives, please see the Western Digital knowledge base.
