Detailed explanation of the interface type of the hard disk

Assembly of computer accessories in the main board in the most complex parts, the motherboard interface is also a lot, we choose the computer configuration to consider the interface between the motherboard and other accessories compatibility, if the interface between each other is not the same, which can not install, the following hard disk interface type introduction.

The IDE's English is all called "Integrated Drive Electronics", or "Electronic integrated Drive", which is meant to be the hard drive that integrates the hard disk controller and the disk body. The integration of the disk and the controller reduces the number and length of cables to the hard drive interface, enhances the reliability of the data transmission, and makes it easier to make the hard drive because the hard drive manufacturer does not need to worry about whether its hard drive is compatible with the controller produced by other manufacturers. For users, hard disk installation is also more convenient. IDE this interface technology from the birth has been constantly developing, performance has been continuously improved, its low-cost, compatible with the characteristics of strong, for its other types of hard disk can not replace the status.

Motherboard IDE Connector

The IDE represents a type of hard disk, but in practical applications, it is also customary to use the IDE to address the earliest IDE type hard disk ATA-1, a type of interface that has been eliminated with the development of interface technology and later branched out into more types of hard disk interfaces, such as ATA, Ultra ATA, Interfaces such as DMA, Ultra DMA, and so on are part of the IDE hard disk.

Scsi

The English of SCSI is all called "Small Computer system Interface" (Small computer system interface), is a completely different interface with IDE (ATA), the IDE interface is standard interface of normal PC, and SCSI is not the interface specially designed for hard disk, is a kind of high-speed data transmission technology which is widely used in small machine. SCSI interface has a wide range of applications, multitasking, large bandwidth, low CPU usage, as well as hot Plug and so on, but the high price makes it difficult as the IDE hard drive, so the SCSI hard disk is mainly used in high-end servers and high-end workstations.

Fibre Channel

The English spelling of Fibre Channel is fibre Channel, same as the Scis interface. Fibre Channel was not originally designed for hard disk design and development of interface technology, is designed for the network system, but with the storage system on the speed of the need to gradually apply to the hard disk system. The Fibre Channel hard disk is developed to improve the speed and flexibility of the multi-disk storage system, and its appearance greatly improves the communication speed of the multi-disk system. The main characteristics of Fibre Channel are: hot-pluggable, high-speed bandwidth, remote connection, large number of connected devices.

Fibre Channel is designed for the environment of a multi-disk system such as a server, which can meet the requirements of high data transmission rates for high-end workstations, servers, mass storage subnets, and peripherals through hubs, switches and point-to-point connections for two-way, serial data communication systems.
