Your pen drive does not have enough storage space to transport films, music or photos? You should try an external HDD with high capacity. If you want to upgrade your home/office computer, 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). You should check the connection interface, so you can avoid the motherboard incompatibility problems. 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", we advise you to choose one with a bigger storage capacity, which will keep you careless of the next upgrade.
