Was it with one disk, or several disks at once ?
I get 80MB/s with a SATA SEAGATE ST375064 (750GB). With a newer controller
and that much disk, I'd expect more than 170MB/s if several disks are used
in parallel.

Actually I'm quite confident other chips working with OpenBSD will work with
NetBSD too. With your card and mine, all code paths have been tested AFAIK.

Disk insertion are working with my controller, I've not tested removal yet
(will do tomorow). More testing is always welcome :)
