Don’t buy this worst product. I have used this product. When I bought this from flipkart. For 8 to 10 days it give me 140 mb of speed. But after one month this hard disk gave me very bad performance. I will tell, what is happened with me. When I connected hard disk to my laptop. It gave me very bad performance. But I think that my laptop is not working properly. But when I connected it wih my friend pc. Their also it doesn’t work properly. It take 25min for copying 1gb file. Please don’t buy this product.
