The Toshiba StorE 1000GB Canvio Black I can only praise. It is small, light, quiet, solid processed, cheap, fast and reliable, comes with any USB connection without extra power supply, working with me with Mac, Parallels, Virtual Box, Win 7 and DVBS2 receiver together with three partitions (NTFS, HFS + and XFAT) formatted five star I can not forgive because I could not test USB 3.0.
