I can get all that data, but can I actually test it somehow? Does linux know anything about NCQ, or is everything abstracted to the controller?

Good question, not knowing the answer I did a quick google and this came to the top:

another good one,

Looks like support wasn't added until 2.6.18 and isn't widely supported until 2.6.19 and 2.6.20.

Ross,

Thank you for the links. Looks like my controller doesn't support NCQ :-(. I have the SIL 3114 based card. Doesn't look like there are any cheap alternatives on the PCI bus, but I think I can live with the performance of this system.
