This drive is very very good because in my view the speed of transfer either read or write is really very good to feel like ultra .I have purchased seagate external hard drive .You would also liketo take it to with you by simply putting in your pocket.The body is small, slim and quiet light. The data write speedfor larger files is 51 MBps( average) and read speed is 62 Mbps minimum.The product is tougher than that of 1 TB models.Its plug and playing the windows.The price of hard drive 4000-4500. So the hard drive is the price is best. ??SLIM AND SUPER DRIVE??
