ATA-4 is the most used controller in computer nowadays. ATAPI, short for Advanced Technology Attachment with Packet Interface, allows CD-ROM and tape drive to share ATA bus with ATA hard disk. ATA-4: ATA-4, also known as UltraTAT or UltraDMA, includes ATAPI4 regulations.Usually, ATA-3 is equivalent to EIDE or FastATA. But there are not many improvements in performance. ATA-3: ATA-3 is released following the introduction of ATA-2.Four devices can be connected to it, including CD-ROM and tape drive. FastATA, simultaneously introduced by Quantum and Seagate, supports hard disk over 504MB and transmits data faster. EIDE, first introduced by Western Digital, utilizes new BIOS and allows computer to manage hard disk with a capacity over 504MB. ATA-2: ATA-2 is often regarded as the fast ATA ( FASTATA ) or enhanced IDE ( EIDE ).ATA-1: ATA-1 is the original hard disk controller.

If you don't know which kind of controller is used in computer, you can refer to the manuals of mainboard and keyboard.ĪTA can be classified in following types. ATA-3 and ATA-4 whose performance has been further improved are being widely used by audio workstation. Invented by IBM, ATA is the second controller placed in hard disk, and it has largely increase the data transmission speed. IDE controller has several variants, and the most common one is ATA ( Advanced Technology Attachment ). The maximum speed of IDE controller is 66Megabytes ( MB ) per second, but many IDE controllers can only reach 33Megabytes per second. IDE controller is usually produced in the mainboard.

It consists of control logical circuit connected to a computer system bus, microprocessor, decoding and encoding circuit used to accomplish the separation of read-in data and compensation of write-in data, data error detection and correction circuit, logical circuit used for controlling the data transmission, serial and parallel conversion as well as formatting in accordance with the computer orders, read-only memory used for storing basic input and output program of disk and buffer for data exchange etc. There are many types of hard disk controller, but the basic components and the operating principle are approximately the same.

Data is written in the disk and read from the disk by hard disk controller according to the disk data format. Also, it detects the hard disk driver status. Hard disk controller is used to receive and interpret the computer order, and then send various control signals to hard disk adapter. Hard disk controller, known as the adapter of hard disk driver, is the interface device between computers and hard disk driver.
