Not sure but from what I gather, SATAII isn't necessarily faster than SATA.
Well the bus is. However the harddrive speed isn't likely to be, as it's the same drive as the SATA one, and it's read/write speed is much slower than the SATA bandwidth.As for which hardware you've got in your machine, SIW can tell you everything you want to know, and quite a few things you probably didn't.
