3.1 SATA 6 Gb/s
SATA 6 Gb/s is the next generation interface for SATA hard drives. It adds to the
functionality of the SATA 1.5 Gb/s interface with the following features:
Native Command Queuing (NCQ ) — server feature for performance in random I/
O transaction environments. It aggregates many small random data transfers and
allows the disk to reorder the commands in a sequential order for faster access.
Improved Power Management — provides improved power management
features including Host Initiated SATA Power Management (HIPM) and Device
Initiated SATA Power Management (DIPM).
Staggered Spin-up — allows the system to control whether the drive will spin up
immediately or wait until the interface is fully ready before spinning up.
Asynchronous Signal Recovery (ASR) — robustness feature that improves signal
recovery.
Enclosure Services — defines external enclosure management and support
features.
Backplane Interconnect — defines how to lay out signal line traces in a
backplane.
