This article is mainly about "what's the difference between ide and ahci". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what's the difference between ide and ahci?"
The differences between ide and ahci are: 1. AHCI mode is specially designed for SATA interface and supports SATA interface characteristics. IDE mode can map SATA disk to ordinary SATA hard disk; 2. The biggest difference between the two modes lies in whether to support native command queue (NCQ).
The operating environment of this tutorial: windows7 system, Dell G3 computer.
The difference between WIN7 hard disk operating mode IDE and AHCI:
1. The AHCI driver is integrated into the WIN7 operating system. AHCI mode is specially designed for the SATA interface and supports SATA interface features, such as native command queue (NCQ) and hot plug.
The English full name of IDE is "Integrated Drive Electronics", that is, "electronic integrated drive". It originally refers to the hard disk drive that integrates the "hard disk controller" with the "disk body".
IDE mode can simulate the mapping of SATA disk to ordinary IDE hard disk without additional loading of SATA driver, but does not support any new features of SATA interface.
2. The biggest difference between the two modes is whether the native command queue (NCQ) is supported.
In theory, NCQ can improve the performance of SATA hard drives by about 30% at most.
To put it simply, after turning on NCQ, the hard drive jumps faster from one program to another, similar to Intel's hyper-threading technology.
IDE mode can take all SATA hard drives by mapping. Because there is no need to load drivers, it has super compatibility and is suitable for WinXP and Win7/8 systems.
At this point, I believe you have a deeper understanding of "what's the difference between ide and ahci". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
