The SATA interface can operate in two modes, IDE and AHCI: 

• IDE – a compatibility mode for older equipment and software. In fact, in this mode SATA capacity is no different from its predecessor, ATA (or PATA) interface;

• AHCI – a new mode for memory devices, where a computer can use all SATA advantages, primarily higher speed of data exchange with SSD and HDD as well as hot swapping of hard disks.  When you activate AHCI mode, it increases the speed of access to files in memory devices and improves overall performance of your computer.
