AHCI vs. IDE: Know the Difference
By Shumaila Saeed || Published on December 28, 2023
AHCI (Advanced Host Controller Interface) enables advanced SATA features like NCQ and hot-swapping; IDE (Integrated Drive Electronics) is an older interface standard for storage devices.
Key Differences
AHCI, standing for Advanced Host Controller Interface, is a modern interface specification that allows hardware to utilize advanced SATA features. IDE, or Integrated Drive Electronics, is an earlier interface standard that was commonly used for connecting storage devices to a computer's motherboard.

AHCI provides support for features like Native Command Queuing (NCQ) and hot-swapping of hard drives, enhancing performance and flexibility. In contrast, IDE, also known as Parallel ATA (PATA), lacks these advanced features and offers a more basic, straightforward interface without support for modern SATA functionalities.
