Summary: This is a defective product. One week after using it began to not mount or be recognized as a valid removable device by my WIndows 7 PC or my Apple Mac laptop. The initial behavior was the slow read and write I/O (much less than 2mb/s for read and writes).
Summary: I hardly ever write reviews, but I felt like I had to this time. I've had this good little drive for a few years now, and it's worked great. It works great when my son stepped on it, it worked great after a lost the cap and the USB port was bent twice.
