CRU-DataPort ( is shipping the US$349.99 ToughTech Duo 3SR, which adds USB 3.0 to the ToughTech series of storage drives.

The new ToughTech Duo 3SR portable RAID storage system works with two 2.5-inch notebook or solid state drives and is designed to simplify data redundancy by writing the same information in real time to both drives with RAID. It sports a ruggedized, hand-sized chassis (measuring 6.3 x 3.5 x 1.4 inches) weighing just over a pound and a half.

Features include an LCD menu to monitor drive health and configure RAID with soft-touch navigation. The all- aluminum ToughTech Duo 3SR stays cool without fans, making the unit extremely quiet., according to the folks at CRU-DataPort.
