NT2 U3.1 The ultra compact design of the NT2 makes this dual-bay RAID storage enclosure one of the smallest in the market, yet it still packs a punch when it comes to flexibility and performance. The incorporation of the latest USB 3.1 Gen 2 technology provides users with super fast transfer rates of up to 10Gbps. At the same time, it is still backwards compatible with the widely used USB 3.0 and USB 2.0 technology. SuperSpeed USB 10Gbps (USB 3.1 Gen 2) By incorporating the latest SuperSpeed USB 10Gbps (USB 3.1 Gen 2) technology, the AKiTiO NT2 U3.1 is able to deliver up to twice the speed of the USB 3.1 Gen 1 and the older USB 3.0 connection, which runs at only 5Gbps. At the same time, the device is still backwards compatible with the widely used USB 3.0 and even USB 2.0 technology. Compact Dual-Bay Design This dual-bay storage enclosure is designed to house up to two 3.5-inch SATA drives with the option to create a RAID set according to your own preferences. The small footprint makes this the ideal storage expansion for your crowded desktop. Hardware RAID Controller With the built-in hardware RAID controller you can mirror the drives with RAID 1 as a reliable backup for your important data, stripe the drives with RAID 0 for optimal performance and maximum transfer rates or you can select SPAN to combine the drives for large storage capacities. Even individually with Non-RAID, the SATA 6Gb/s interface allows each drive to run at full SATA-III speeds.
