portable external hard drive

Portable hard drive are one of the most useful external hard drives on the market. They are really small, which means they can fit in your pocket and their storage capacity is quite big.

Physical Hard Drive Size

The size of portable external hard drives are usually the same size as a laptop hard drive (2.5 inch) compared to the bigger hard drives (3.5 inch).

This means that you can hold the hard drive in the palm of your hand and bring them around with you.

Portable Hard Drive Capacity

A portable hard drive has a smaller capacity then the normal 3.5 ” hard drives. It is the same hard drive as a laptop hard drive, which means that it has sizes between 20Gb – 500Gb. However, for most users 300Gb – 500Gb is big enough. This is why they are so much better than the small flash drive.


There are a few little disadvantages to the portable hard drive. However these are so minor that it would not deter me from buying one.

  • Firstly, the price of smaller hard drives are more expensive than bigger 3.5″ hard drives. This means that you will paying more per Gigabyte than you would pay for a bigger hard drive.
  • The second disadvantage in buying a portable external hard drive would be the speed of the platters. In most normal internal hard drives the speed is around 7200 RPMs while these small hard drives usually run at 5400 RPMs. This does mean that the hard drive is slightly slower and it will take slightly longer to run programs and move files.
