I have recently bought this hard disk from the online shoping website amazon. And I am quiet satisfied with this product. I was lookind for 1TB harddisk after searching on my websites I found that ( Western digital) is the only company which is selling reliable and provides hardisk at the cheapest possible rate. It costs me 3800 which is good for it.
Now I have transfered all my data from my laptop to this harddisk. Best part of this hard disk that transfer rate is great, I almost transfered 450 gb of data in just 25mins which I think is brilient. Now I feel my all data is fully secured. Any one lookin for buying external hard disk just go and buy this WD 1TB HARD DISK I think it will meet your all requirements to safe your personal data.
Thank you.
