I am using this external hard disk drive for last 1 years.
I bought it from flipkart for rs 4700. Price is not to high it is affordable.
I am using this hdd for back up my datas. This hard disk is compatible with all the os. The transfer speed of file is just amazing.I get 35 mbps speed.its just awesome. Its usb version is 3.0 & it compatible with all the os. Its weight is very less and size is small also easy to carry.Its a good external hard disk.if u look for a external hdd under 5k then go for it.
