The TowerRAID TR4UTP 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.
USB 3.0 Raid
This review is from: SANS DIGITAL TowerRAID TR4UTP 0, 1, 10, 3, 5, Clone (N-way Mirror) with Hot Spare, and JBOD 4 x Hot-Swappable 3.5" Drive Bays USB 3.0 (backward compatible with USB 2.0) and eSATA 4 Bay USB 3.0 / eSATA Hardware RAID 5 Tower w/ 6G PCIe 2.0 HB
Pros: I really liked the specs on this unit. It was just what I was Looking for In a light raid drive enclosure. USB 3.0 and e-sata plus 4drive bay. It was easy to install and had good front indicators.
Cons: I tried 4 Samsung drive, 4 seagate drives I tried different combinations like three drives only but it would not work. It wool never show up under disk management in Windows XP or Windows 7. So disappointing. Now I have to RMA it back to Newegg as a damaged drive. That's what I think happened because it had no shipment packaging only the store box.
Other Thoughts: I really wanted this drive to work.
