I have bought this Transcend Hard disk from Flipkart in affordable range. And I am using it daily. I have stored my important documents and movies and songs. Its memory is 1 TB .It is available in 320GB, 500GB, 1TB and 2TB also. I have 1TB with 1 year warranty. It has one problem of slow connectivity and the sharing speed is slow sometimes.
It can’t take the overload of sharing. I am facing this problem rarely, but this was not expected from this Transcend hard disk .Guys, think before buying this product . You have other options also in the market.
