Hey friends I have WD My Passport Ultra 1 TB hard disk. I buy from a shop. I buy this hard disk for 4, 500 Rupees only. It cost me 1 time but I get 1 year guarantee. It is very stylish. It performance is very nice. Transfer speed is 60 Mbps- 120 Mbps. It has 3.0 USB port. When I purchase that time I think, I spend more money on single external hard disk. When I use this hard disk I too much happy. Performance of hard disk is very nice. Features are very awesome. Hard disk can easily carry in pocket. Service is very nice. It is very valuable for me!
