External hard drives
give lot of portability. However these external hard drives have higher
access time compared to desktop drive because of USB interface. But because
of USB interface, CPU utilization is less in the range of 8.4 to 10. This
means less load on CPU.
Iomega, Freecom, Transcend
are some of the manufacturers of external hard drives. These drives require
external power supply and are most suitable for desktop use. When you
are selecting external hard drive, check whether the manufacturer is offering
a carry bag, data cable and power supply if it is externally powered.
Also check the warranty
offered by the manufacturer. Now a days, some of the manufacturers offer
warranty for 3 years.
