I have purchased this product because I need to store my bulk data. As my laptop hard disk was almost getting full then I took the decision of buying this hard disk. I choose this brand over others because my friends are using WD hard disk and they are not getting any problem till date. And moreover we have a WD service center in our city. The main thing I like about this hard disk is that it is USB 3.0 compatible with USB 2.0 as well as. The 3.0 USB works great it gives 60 to 70 Mbps per second. It is also a handy and portable hard disk. I also like about its pricing matter its cost is low as compared to other HDD. But only one thing I did not like about the hard disk is that it decreases its speed in USB 2.0 which is a major drawback but, other than this the product is a good one.
