NT2 U3

As of November 1, 2016, the NT2 U3 has been discontinued and this model is no longer being manufactured, sold or maintained.

The NT2 U3 was a dual-bay RAID storage enclosures with a screwless design to easily install and replace up to two 3.5" hard disk drives. The hardware RAID controller supports Non-RAID, RAID 0 and RAID 1. It features a USB 3.0 SuperSpeed connection.

This model has been replaced by the NT2 U3.1 with a faster USB 3.1 Gen 2 interface up to 10Gbps. The NT2 U3.1 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

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. Installing the 3.5" hard drives is quick and easy, thanks to the screwless design. By incorporating USB 3.0 SuperSpeed technology, AKiTiO's NT2 U3 is able to break the USB 2.0 barrier, delivering up to 10 times the speed of the older USB connection. At the same time, it is still backwards compatible with the widely used USB 2.0 technology.
