SATA hard disk interface is the connection between the hard disk and the host system, the role is to transfer data between the hard disk cache and the host memory. The connection speed of the computer is related to the SATA hard disk interface, because different SATA hard disk interface can determine the connection speed between the hard disk and the computer, so in the whole system, the role of the SATA connector hard disk interface can directly affect the speed of the program and the performance of the system. From the point of view of each household, the hard disk interface were IDE, SATA two specifications, they each have their own advantages and characteristics, users need to choose according to their own situation.
IDE interface hard disk and motherboard interface IDE interface hard disk is generally what we commonly known as parallel specification PATA hard disk, the majority of desktop storage systems are currently used is called Ultra-ATA parallel bus interface hard disk products, such specifications technology is since the 80s has been used in desktop systems as the mainstream internal storage interconnect technology, due to the use of a very wide range of fields, and a long time, so the mature technology can bring more large-scale integrated manufacturing of low-cost and rapid development of high capacity. Because of its wide range of applications and longevity, the mature technology has been able to bring about lower costs for larger scale integrated manufacturing and rapid growth in high capacity.
Due to the long period of time without change, in terms of data transfer, this IDE interface hard drive appears to have some lag, because the current mainstream PATA hard drive can only support ATA/100 and ATA/133 two data transfer specifications, the maximum transfer rate can only reach 100 or 133MB per second, which can only meet the current general case of high-capacity hard drive data transfer. In addition, the 80-pin data lines used by these drives are miscellaneous and messy inside the chassis, which can impede the flow of air in the chassis, thus affecting the system’s heat dissipation. Although the disadvantages are obvious, but for some of the original old users, because the original motherboard platform does not support the SATA interface, this IDE interface PATA high-capacity hard drive is still the first choice, there are some users will think that this type of hard drive is technically mature, stable, so also choose this type of PATA hard drive.
In terms of technical features, it has to be admitted that PATA hard drives are inferior to SATA hard drives in many aspects such as installation, transfer rate and power consumption, shock resistance and noise. Because SATA hard disk it has a faster external interface transfer speed, data verification measures are more complete, SATA1.0 specification provides for a standard transfer rate of 150MB / S, so you can take full advantage of the performance of the SerialATA interface, because the theoretical value of ATA100 is 100MB / s, even ATA133 is also up to 133MB / s In addition, the first step in the installation is the SATA connection.
Also in terms of installation first of all the SATA connection cable is very convenient and the most important feature of SATA is that it supports hot-swapping. Serial SATA method through better data verification method, low signal voltage can effectively reduce a variety of interference, thus more effectively improve the efficiency of data transmission, and the new SATA hard drive connection cable can also be more conducive to the internal heat dissipation of the chassis.
