I am fairly disappointed in this drive. While it is cheap (I paid CAD$ 8.20 for it on a sale)
Writing speed with teracopy is at 8 MB/s, so slow even it this was a USB 2.0 drive. Read speed w/ teracopy was at 45 MB/s.
Run a benchmark, available at ( http://usbflashspeed.com/50447 ) which shows 19 MB/s write speed an 57 MB/s read speed, so values under the limit of USB 2.0
The unit also is hard to insert in a usb slot, struggling to get in and out.
On the plus side, it looks nice (I got mine two ones in blue), seems fairly sturdy and is compact, but not so small as to use it.
If you're looking for a true USB 3.0 drive, look elsewhere I'm afraid. And if you look for a USB 2.0 drive, there's better choices than this one, especially now that it's on for 13 CAD$ rather than 8.20 CAD$
