Description
Native Command Queuing
(NCQ)
Allows the device to reorder commands for more efficient data
transfers
Collapses a DMA Setup then DMA Activate sequence into a DMA
Setup only
Auto Activate for DMA
Hot Plug Support
Allows for device detection without power being applied and
ability to connect and disconnect devices without prior
notification to the system
Asynchronous Signal
Recovery
Provides a recovery from a loss of signal or establishing
communication after hot plug
3 Gb/s Transfer Rate
Capable of data transfers up to 3Gb/s
ATAPI Asynchronous
Notification
A mechanism for a device to send a notification to the host that
the device requires attention
Host & Link Initiated Power
Management
Capability for the host controller or device to request Partial and
Slumber interface power states
Enables the host the ability to spin up hard drives sequentially
to prevent power load problems on boot
Staggered Spin-Up
Reduces interrupt and completion overhead by allowing a
specified number of commands to complete and then generating
an interrupt to process the commands
Command Completion
Coalescing
Technology that allows for an outside the box connection of up
to 2 meters (when using the cable defined in SATA-IO)
External SATA
