The Icy Dock ICYRaid MB662U3-2S, unlike other external USB 3.0 enclosures has the hardware capability to run drives in RAID, independent of the PC. The ICYRaid MB662U3-2S replaces the discontinued MB662UEAB-2S which used the older USB 2.0 and FireWire connection with a much faster and more widely used USB 3.0 port. Users can install a pair of two 3.5 HDDs up to 4TB in capacity each for a total of up to 8GB of storage inside the Icy Dock MB662U3-2S. To cool both drives when they are continuously used, the ICYRaid MB662U3-2S is equipped with a 40mm Sunon MAGLev fan that operates silently and can be adjust through a built-in fan controller. Users can configure drives installed inside the MB662U3-2S in RAID 0, RAID 1, BIG, or JBOD just by simply moving the RAID toggle switch and pressing the reset button while the enclosure is on. No further steps are required, other than formatting the drives or adjust the partition when necessary of course. The Icy Dock ICYRAid MB662U3-2S is compatible with either Mac or PC and comes with a three-year limited warranty."
