The most useful external hard drives in the market are the portable hard drives. They are easy to carry and come in handy. Even though they are small in size, their storage capacity is quite big.
Physical Size
Portable external hard drives and laptop hard drives are the same in size (2.5 inch) compared to the bigger hard drives (3.5 inch).
Capacity
A portable hard drives capacity varies between 20GB – 500GB.
Disadvantages
Firstly, compact sized hard drives are costly compared to the bulky 3.5" hard drives. This means that a bigger hard drive is cheaper compared to a portable one as it charges more per Gigabyte.
Secondly, the speed of the portable hard drives usually run at 5400 RPMs which is quite less compared to the internal hard drives speed, which runs up to 7200 RPMs. Hence, portable hard drives run slightly slower, therefore, taking longer to run programs and transfer files.
