SATA NCQ support
In the High-End Drivemark 2000, the one w/o NCQ performs more I/O's per second than the one with it. What drive was that? 'I/O's per second' is basically latency related: rpm, seek time etc. No point in comparison unless of the same or similar type. Guess you didn't go to the site. Guess I didn't.

SATA NCQ by software?
IMO the man page(s) should include things like how to turn SATA NCQ on/off. And if the device drivers don't provide the functionality, they should. So IMO this is a PR. But we can run it past -hackers, that's fine. So, for those of you on -hackers just tuning in, can someone please tell me how to turn SATA NCQ on?
