A portable hard drive allows you to carry your operating system and any data stored with it from computer to computer, making it a useful option for a computer user on the go. Installing an operating system (OS) on a portable hard drive can save you time and energy by giving you the same desktop on every computer you use. Portable hard drives provide you all the resources of a normal hard drive, but usually at a slower speed.
