I purchased this hard disk for the netbook which I had as its internal memory was only 250GB(gigabytes). and the 1TB(Terabytes) was a helpful for my needs. the best thing about this hard disk is its really portable. Its pocket size similar to your wallet(men).
I got this hard disk in 2009 but still after 6 years its work fine and the memory is best in class memory. the price is also affordable in this class.
