Today many modern technologies are implemented to manufacture external hard drives and the technologies include SATA, IDE or SCSI with portable disk enclosures with SCSI, USB, 1394 firewire, ESATA, IEEE interfaces that help to connect to the computer.

The first commercial hard disks that were manufactured were very huge in size and cumbersome. They were oversized than the computer and used to look like an external hard disk. In just few years, the hard disks have evolved to be a small and compact device that looks sleek but stores huge data. These hard disks have gained huge popularity as we get additional space to store that is safe and secure like a pc. These external hard drives are just like a pen drive and do not require software or an operating system to use it.

The structure of the external hard drives looks almost similar to the regular hard disks. In fact we can actually say they are regular hard disks mounted with a portable disk enclosure for protection. Earlier, the capacity of the internal hard drives was also very less. However, today we get a minimum of 160 GB external hard disk and you can get a maximum space of 4TB (this would definitely increase in the future). The design of the external hard disk is also similar to that of the external drive. They have the same platters and the moving heads of the traditional hard disks. External hard disks are much tolerant to physical shocks. External hard drives do not posses any compatibility issues.
