It says:
"Over and above the power management specified in the ATA/ATAPI
specification, one can aggressively control the power consumption of
SATA hosts, the SATA bus, and the SATA device. [...]
There is little demand at the present time for aggressive, automatic
power management under Linux."
What about laptops on batteries? Pavel reports a 1W power draw by his
ThinkPad's ICH7M SATA controller [1]. It would be neat to eliminate
this when the disk is not in use (and powering up the silicon can't
take much longer than spinning up a chunk glass to 7200RPM).
