Guys, if you are looking for some external hard drives, this is one of the product you will like to buy. Worth buying for if you want an HDD. The company has got its name and has done to that extent. It is slim comparative to other HDD and also has a very sleek and beautiful design. It comes with a USB 3.0 and a guide. The transfer speed depends on the performance of your device, file which is transferred and other factors too. It does not have any heating problem regardless of how much data you are transferring. It also has an led light which makes you know the condition of it while attached to other device. It also has an backup system which is very useful if you have made a mistake during the work. The HDD which I have consist of 931 GB.
