No, I don't have the system now.

I don't think so. It's *very* unlikely a driver can mess up linear speed
- it's far more easier to mess up random IO.

I don't know why it's so (it might be cause by FreeBSD's tiny MAXPHYS),
but it's probably not the driver's fault. I've seen this behaviour with
other controllers (including plain SATA).

Look at the read speed.
