Unfortunately I currently don't have another SCSI controller around
(only onboard or broken ones).

I tested with 2.6.18-rc3.
"dd if=/dev/sda of=/dev/null bs=1M count=1024" (for read)
"dd if=/dev/zero of=/dev/sda bs=1M count=1024" (for write)
each 5 times (results were almost the same.. maximum difference was 0,1mb/s)

default arguments: ~37,5mb/s (read) ~37,6mb/s(write)
safe=1: ~2,8mb/s (read) ~2,3mb/s (write)

Regards,
Robert
