I bought WD My Passport 1TB harddisk on paytm for the amount of Rs. 5500 with 1500 cadhback on paytm 3 months before. I always prefer to buy the branded electonic items. This is the branded and most economical one for the users. The problems I faced with the external hard disks are
whenever I try connect with pc or laptop the error msg will always appear like there was a problem with ur device.
It is easily corruptable one. Always need to format the drive. The security related problems occurs in the 1tb HD.
As for as my opinion is if you want to go with less memory and most economical go with WD MY PASSPORT 1TB harddisk. Or if you want most compatable one means go for an higher version
