Its handy easy to use external hard drive. It can be directly connected using the cable provided with the WD hard disk. The transfer speed is generally about 30MBps ( Mega bytes per second) for a USB 2.0 port and the speed increases about 80MBps for USB 3.0 port. this is the speed every individual likes this have if we possess 1TB of storage. The only demerit of this hard disk is handling problem. It should be properly handled so as to avoid jerks and shocks to the hard disk this way it can last for long time.
