What is IDE hard disk?

IDE stands for Integrated Drive Electronics. In the hard drive department most of the computers are still relying on the venerable IDE technology. IDE is the common term that is used to refer the type of the hard drive connection technically. The IDE technology is referred by the term ATA which stands for Advanced Technology Attachment. Than the term IDE, the ATA is used in common. There are two types of interface connection for the ATA drives they are Serial ATA and Parallel ATA

ATA/IDE origin

The ATA was originated in the year 1984 and was commonly used among all the system. This technology was used as a method to combine the hard drive and the controller for making a direct connection to the bus of the old IBM Advanced Technology (AT) computer. In the ATA interface drives this particular controller/drive combination is used which is originated by the marketing departments of some manufactures. In the modern hard dives PATA or the SATA are used and which can be seen in detail as follows.

PATA Hard drive

PATA is the old technology which stands for the Parallel ATA. This PATA is a 16 bit parallel interface in which the 16 bit of the data are transmitted down simultaneously in an interface cable. Ribbon cables with the 40 pins are used to connect the computer system with the drives. In the laptop PATA drives 44 pins are used to connect and give the interface. The next feature of the PATA cable is that the interface can be created with 2 drives in one single cable. This two drives are controlled with the help of the jumpers in order to determine the position by which the drive should be activated and used that is either Master or Slave.

SATA Hard drives

SATA hard drive stands for the Serial ATA. This particular technology came into existence in the year 2000 officially. But the computer systems adopted this technology from the year 2003. The SATA sends single bit of the data at a time down the interface cable. There is no synchronization needed so that this enables to use smaller cables and this also allows high cycling speeds. This is the main advantage of the SATA cables and the SATA drives. This helps in reducing the complexity of the cabling. The interfacing feature is completely different from the PATA while it is still compatible on the ATA standard of the software level. There are seven pins in the SATA cable which helps in allowing much thinner cables that are useful to enable easier routing within the computer case itself. Every cable has only one device connection so that there is no necessity for the jumpers for configuring the system hard drive into master position or the slave position.
