[comp.sys.ibm.pc.hardware] WD 7000-FASST2 Question

I have a question regarding a Western Digital 7000-FASST2 controller
I recently installed in my computer.  The data transfer rates are quite
slow (93 kbs for .5k blocks) when the device driver sstbio.sys is not 
installed in my config.sys.  The transfer rate is fine (500-550kbs) when
it is installed.  Is this normal?  Does the Adaptec 1542b require a driver
also to get the higher rate?

Also, without the driver PCTools PCBackup program fails in high speed
but works fine with the driver when backing up to floppies.

I would appreciate any help or comments - I just want to be sure that
the controller and the installation are okay.

Thanks,
Chris
