I needed an external hard disk for saving all the games and movies from my laptop so I bought this WD Passport Ultra 1 TB model from an online retailer. There was an offer on that day so I got it at a very cheap rate of Rs. 3500. Other hard disks of same capacity were priced higher than this. I have been using this more than one year and it gives no problem. Transfer speeds are also very good and I would recommend buying this.
