This model has been replaced by the NT2 U31C, which utilizes a USB-C connector and a different kind of RAID switch. The NT2 U31C has also been designed for two 3.5" drives and comes with a built-in hardware RAID controller supporting Non-RAID, RAID 0 and RAID 1.



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.
