A nice aluminum case of good construction / finish, I connected using a USB 3.0 Y-cable The integrated drive is a 2.5 "drive mechanics and 5xxxtpm cache 8mo. The transfer rates are average usb 3.0 ("Around" of 70MB / s) .And on my ASUS motherboard, the case is compatible with USB Boost which allows up to over 100MB / s. An LED shows disk activity. I am satisfied with this boitier.D'ailleurs, I took a second to answer the same type of need. Note that a carrying case is included.
