ide interface standards are mainly used for

IDE interface (Integrated Drive Electronics) is an electronic integrated drive, which is a hard drive that integrates the "hard disk controller" and the "disk body". The IDE interface standard is mainly used for the connection between the motherboard and the hard disk, and the motherboard and the optical drive.

Integrating the disk body and the controller reduces the number and length of cables in the hard disk interface, and the reliability of data transmission is enhanced. Technology that makes hard drives easier to manufacture. (Recommended study: PHP Video Tutorial)

Therefore, hard disk manufacturers no longer need to worry about whether their hard disks are compatible with controllers produced by other manufacturers. For users, the hard drive is also more convenient to install. The interface technology of IDE has been continuously developing since its birth, and its performance has been continuously improved. Its low price and strong compatibility have created a position that cannot be replaced by other types of hard drives.

The commonly referred to as the IDE interface is also called the ATA interface. The English spelling of ATA is "Advanced Technology Attachment", which means "advanced technology attachment".

The ATA interface was first jointly developed by Compaq, Western Digital and other companies in 1986, and began to be used in desktop systems in the early 1990s. It uses a 40-core cable to connect to the motherboard. The original design could only support two hard drives, and the maximum capacity was limited to 504 MB.

Notes

Various IDE standards are well backward compatible. For example, ATA 133 is compatible with ATA 66/100 and Ultra DMA33, and ATA 100 is also compatible. Ultra DMA 33/66.

It should be noted that for ATA 66 and above IDE interface transmission standards, a special 80-core IDE cable must be used. Compared with the ordinary 40-core IDE cable, it adds 40 ground wire to improve signal stability.

IDE represents a type of hard disk, but in actual applications, people are also accustomed to using IDE to refer to the earliest IDE type hard disk ATA-1. This type of interface has been developed with the development of interface technology. was eliminated, and later developed more types of hard disk interfaces, such as ATA, Ultra ATA, DMA, Ultra DMA and other interfaces are all IDE hard disks. At present, the hardware interface has been transferred to SATA, and the IDE interface will disappear from the stage sooner or later.

Advantages and Disadvantages

IDE interface advantages: low price, strong compatibility, high cost performance

IDE interface disadvantages: slow data transmission speed, cable The length is too short and there are few connected devices

Currently, few newly shipped motherboards have IDE interfaces, and new storage devices do not have IDE interface types. The last batch of IDE interface motherboards and IDE interface devices leaving the factory have also passed the warranty period and are facing the end of their lifespan; therefore, from a purchasing perspective, you can completely forget about the IDE interface.
