Using the Hard Disk Drive
Your computer comes with a removable 2.5-inch SATA (serial ATA) hard disk
drive.
You can enable AHCI (Advanced Host Controller Interface), a programming
interface for SATA host controllers. AHCI defines transactions between the
SATA controller and software and enables advanced performance and
usability with SATA. When the SATA AHCI mode is enabled, your system can
support SATA native command queuing, aggressive power management,
and so on.
Select models are equipped with a hard disk heater that automatically turns
on for low temperature operation.
