Our friends,
I read some article but I'm confused
AHCI vs IDE
ATA vs IDE
Thank you for your reply,Which aspects of it are you confused over? Otherwise, you are asking the exact same thing in a different way.

Here is a much easier article to understand the differences between ACHI and IDE modes:

People will only run their drives in IDE mode if there is some kind of hardware incompatibility issue, as AHCI is faster and the standard for quite some time now. It is the same storage controller, just a different mode.
Not really. IDE/ATA/ATAPI encompass the interface as well as the programming/software model (BIOS and OS). AHCI in at least the first two iterations was merely the programming model. AHCI did not usher in Serial ATA, that was it's own separate effort and specification. Maybe they have subsequently merged the two in the past few years but it wasn't so for several years....AHCI (Advanced Host Controller Interface) replaced the older IDE/ATA standards with something better. It introduced SATA cables, these are smaller.
