Isn't your USB drive enough to move films, music or photos from one computer to another? We recommend an external hard drive with high storage capacity. Are you planning for a home/office computer upgrade? You should try an internal hard drive with a 3.5 inches form factor (for desktop systems and servers) or one with a 2.5 inches form factor (for notebooks). In order to avoid the motherboard incompatibility problems, you should take into consideration the connection interface. Depending on the motherboard, you should choose a hard disk compatible with the spindle speed and the transfer rate. Moreover, because in the hard disk field "more" means "better", our advice is to choose one with a bigger storage capacity, which will keep you careless of the next upgrade.
