stands for Integrated Drive Electronics. In a later time, name "ATA hard
drive" was used for newer version of IDE hard disk drives. The original IDE name reflected the innovative
integration of HDD disk controller with hard disk drive itself, which
was not found in the earlier storage disks. Moving the HDD disk controller
from the interface card to the hard disk drive itself helped to
standardize interfaces, and to reduce the cost and complexity. IDE hard
disk drives were widely used in desktop and notebook PC for long time
until the serial ATA hard disk interface was introduced several years
ago. Although all new PC systems use SATA hard disks, IDE ATA hard
drives are still available for upgrading older computers.
One of popular IDE HDD brands is Western Digital which ha for long time
enjoyed reputations of high performance, low noise, great compatibility
and best warranty in the industry.
