General FAQ

What are IDE, AHCI and RAID mode for in BIOS setup menu?

IDE mode is older technology which let SATA HDD run as IDE HDD when SATA HDD was connected. Advanced Host Controller Interface (AHCI) is an interface specification that allows the SATA HDD to enable advanced SATA features like NCQ and hot swap. AHCI mode will give the HDD more performance and speed than IDE mode. RAID is a storage technology that provides increased reliability and functions through redundancy. This is achieved by combining multiple disk drive components into a logical unit, where data is distributed across the drives in one of several ways called "RAID levels" like “RAID 0,1,5”. If install Windows XP with AHCI/RAID mode, it needs to load SATA controller driver during Windows XP installation routine.
