Description 4TB 2.5 Inch External Hard Drive 4TB 2.5 Inch External Hard Drive. An external hard drive is a piece of equipment that can be connected to your computer to increase its storage space. Unlike the hard drive that’s installed in your computer, an external HDD is portable and can also be used to store files from multiple devices. Do you need one? If you find yourself in situations where file transfers need to occur quickly, then the convenience (and extra up-front cost) of a faster external HDD is worth considering.

You can start saving your digital files to this external HDD within seconds of removing them from the box.
