Increased learn/write efficiency
Native command queuing
Scorching Swapping (unplugging / plugging in a SATA Drive when PC is on)
Increased Quantity of Drives supported (16 vs 2 on IDE)
Helps SSDs
Full RAID supportAbout IDE ModeIDE (Built-in Drive Electronics) Mode is an operation mode for SATA drives that permit them to perform as legacy IDE/PATA (Parallel ATA) drives when used with older working programs that don’t acknowledge SATA.In comparison with AHCI Mode, IDE Mode doesn’t supply help for hot-plugging performance and is mostly rather a lot slower across-the-board than AHCI.Ought to You Allow AHCI Mode?So, must you allow AHCI Mode?Until you’re nonetheless operating a pre-Home windows Vista (or XP with updates) working system, sure!
