Which Hard Drive do I have?

Tutorial written by KenB

There are 3 types of hard-drive. (SSD which is relatively new is not covered in this tutorial).

The 2 HDDs featured are, at the time of writing, by far the most common.

  • PATA – commonly known as IDE ( Integrated Drive Electronics )
  • SATA ( Serial Advanced Technology Attachment ).

Sata Hard Drive  - Serial advanced Technology Attachment

IDE ( shown above ) is an older technology. It was first introduced into PCs in about 1986.

It is probably easiest to identify the hard drive by the cable. An IDE cable is broad ( 80 wires ) and grey.

The newer hard drives transfer data faster than the older IDE drives.
The connections are different: ( see below )

Faster IDE Cable

The cable for this drive is much smaller than the older IDE cable.

In a new future we shall see a propagation of the SSD Hard Drives that allow Operating systems to load faster. So stay tuned for a part 2 of “Which Hard Drive do I have?”
