The IDE interface commonly referred to is also called ATA interface. The English spelling of ATA is "Advanced Technology Attachment", which means "advanced technology additional device". The ATA interface was first developed by Compaq and Western Digital in 1986, and was applied to desktop systems in the early 1990s. It uses a 40-core cable to connect to the motherboard. The initial design can only support two hard disks, and the maximum capacity is also limited to 504 MB.
Since its birth, a total of 7 different versions have been launched, namely: ATA-1 (IDE), ATA-2 (EIDEEnhanced IDE/Fast ATA), ATA-3 (FastATA-2), ATA-4 (ATA33), ATA-5 (ATA66), ATA-6 (ATA100), and ATA-7 (ATA133).
ATA-1
The ATA-1 has a socket on the motherboard, supporting a master and a slave. The maximum capacity of each device is 504MB, and the supported PIO-0 mode transmission rate is only 3.3MB/s. ATA-1 supports PIO modes including PIO-0, PIO-1, PIO-2 modes, and also supports four DMA modes (not practically applied). The ATA-1 interface has a hard drive size of 5 inches, rather than the mainstream 3.5 inches now.
ATA-2
ATA-2 is an extension of ATA-1, commonly known as EIDE (Enhanced IDE) or Fast ATA. It adds 2 PIO and 2 DMA modes (PIO-3) on the basis of ATA, which not only increases the maximum transmission rate of the hard disk to 16.6MB/S, but also introduces LBA address conversion method, breaking through the inherent 504MB limit and can support hard disks up to 8.1GB. In the BIOS settings of computers that support ATA-2, you can generally see the settings of LBA (Logical Block Address), and CHS (Cylinder, Head, Sector). At the same time, the motherboard with the EIDE interface generally has two EIDE sockets, which can also connect a master and a slave device respectively. In this way, a motherboard can support four EIDE devices. These two EDIE interfaces are generally called IDE1 and IDE2.
ATA-3
ATA-3 did not introduce a higher speed transmission mode, and there was no improvement in transmission speed, and the maximum speed was still 16.6MB/s. Only the power management solution has been modified, and a simple password protection security solution has been introduced. But an epoch-making technology has been introduced, that is (Self-Monitoring, Analysis and Reporting Technology). This timely monitors hard disk components including magnetic heads, discs, motors, circuits, etc., and detects the monitored objects through the detection circuit and the monitoring software on the host, analyzes and compares their operating status and history with preset safety values. When the range of the safety values is exceeded, a warning will be automatically issued to the user, thereby making effective predictions for potential hard disk failures, improving the security of data storage.
ATA-4
Starting from the ATA-4 interface standard, Ultra DMA data transmission mode is officially supported, so it is also accustomed to calling ATA-4 Ultra DMA 33 or ATA33. For the first time, Double Data Rate (double data transmission) technology was used in the ATA interface, allowing the interface to transmit data twice in one clock cycle, and there is a data transmission once in each clock rise and fall period, so that the data transmission rate will be increased from 16MB/s to 33MB/s. Ultra DMA 33 also introduced a new technology - Redundant Verification Measurement (CRC). The design policy of this technology is that the system and the hard disk transmit redundant verification codes cyclically with the data during transmission. When the other party collects, the school’s difficult codes will be checked. Only when the correctness is fully checked will the obtained data be received and processed, which has a strong guarantee for the security of high-speed data transmission.
ATA-5
ATA-5, also known as "Ultra DMA 66", is based on the Ultra DMA 33 hard disk interface and also uses UDMA technology. Ultra DMA 66 allows the host to receive/send data rate to 66.6 MB/s, twice that of U-DMA/33. The core technology redundant verification method (CRC) of the previous generation Ultra DMA 33 has been retained. While the working frequency commission is being given, the electromagnetic interference problem has begun to be in the ATA interface. In order to ensure the accuracy of data transmission and prevent electromagnetic interference, the Ultra DMA 66 interface has begun to use 40-pin 80-core cables. The 40-pin is to be compatible with previous ATA slots and reduce the increase in costs. The newly added ground wires in the 80 core are all ground wires, which correspond one by one to the original data wires. This design can reduce electromagnetic interference between adjacent signal wires.
ATA-6
Like ATA66, the ATA100 interface and data cable also use a 40-pin 80-core data transmission cable, and the ATA100 interface is fully backward compatible. Devices that support ATA33 and ATA66 interfaces can continue to be used in the ATA100 interface. The ATA100 specification can easily deal with the difficult problems of the current ATA33 and ATA66 interfaces. ATA100 can make the external transmission rate of the hard disk reach 100MB/s. It improves the integrity and data transmission rate of the hard disk data, and has a great effect on improving the performance of the disk subsystem of the desktop system. CRC technology is more effective in improving the integrity and reliability of data in high-speed transmission.
ATA-7
ATA-7 is the last version of the ATA interface, also called ATA133. Only Maxto has launched a series of hard drives that adopt the ATA133 standard, the first IDE hard drive with an interface speed of more than 100MB/s. Maxto is currently the only manufacturer to launch such interface standard hard disks, while other IDE hard disk manufacturers have stopped developing IDE interfaces and instead produced Serial ATA interface standard hard disks. The ATA133 interface supports 133 MB/s data transmission speed. When the ATA interface developed to the ATA100, the cable properties, connectors and signal protocols of this parallel interface all showed great technical bottlenecks, and it is quite difficult to break through these bottlenecks in technology. The emergence of new hard disk interface standards is inevitable.
Since its birth, a total of 7 different versions have been launched, namely: ATA-1 (IDE), ATA-2 (EIDEEnhanced IDE/Fast ATA), ATA-3 (FastATA-2), ATA-4 (ATA33), ATA-5 (ATA66), ATA-6 (ATA100), and ATA-7 (ATA133).
