The adaptec may be a little faster, but I would stick with the WD1007-WA2
because of formatting problems.  Specifically, your disks are currently
working using a WD1007aa-WA2.  If you replace the controller with a
different brand you will most likely have to do a low-level format of
the drive.

Hopefully you have a current backup :-)
