Brief Introduction to IDE

IDE is short for Integrated Drive Electronics. It intends to refer to the hard drive which integrates controller with disk body. The IDE we usually mention means an interface technology of devices, such as hard disk.

Name: IDE

1.Introduction
IDE is also called ATA (Advanced Technology Attachment) interface. At present, most hard disks used by PC (Personal Computer) are compatible with IDE by using a 40-wire cable to connect the hard disks with motherboard or interface card. The action of integrating disk body with controller reduces the number as well as length of cable of the hard disk interface. And by doing so, the transmission reliability is enhanced and it becomes easier to produce the hard disk, because hard disk manufacturers don't need to be worried if the hard disk is compatible with the controller produced by other manufacturers or not. And it is also more convenient for users to install the hard disk.

2.Entry-level Server
Currently, IDE interface is used in a large part of low-level entry servers. The benefit of doing so is low cost and it's a good choice for the environment which is not so demanding for performance. However, servers using IDE interface have serious defects, including bottleneck of speed, not hot swappable and hard to realize the stability of data protection. Even though many server manufacturers release IDE-based RAID (Redundant Arrays of Independent Disks, a way to protect the reliability of data on the hard drive), which is only limited to small-flow data, it is powerless for sudden large flow data. Considering this situation, the current servers mainly use SCSI interfaces which are stable and fast in transmitting.
