I had a spare 2.5" laptop hard drive sitting in a drawer and needed an "external" USB drive for use with my Sling AirTV for local recordings. I tried a USB Flash Drive, but the AirTV kept saying it was of the wrong type, and I didn't want to spend the money on another full price external drive. Bought this slick little case because it said it went up to 6 Gb/s, which matched the speed of my western digital 2.5" drive. The day it arrived I popped my drive right in the case, plugged it in (which then glowed a very cool blue), and the AirTV formatted the drive and worked perfectly on the very first try. Excellent product for the price!
