Intel Rapid Storage Technology (RST) is a solution built into a range of Intel chipsets. On platforms that have RST support built and enabled in the computer’s BIOS, it allows users to group and manage multiple hard disks as single volumes. This functionality is known as the Redundant Array of Independent Disks (RAID).

Which is better AHCI or ATA?

SATA devices perform better when configured as AHCI, rather than ATA; AHCI reduces the time it takes to save and open files on the hard drive via the native command queuing (NCQ) feature, which optimizes multiple read/write commands.
