Storage evaluation
SATA performance is equal across the three boards, and any limitations
don't appear to lie with the chipsets.
USB performance is lower on the two AMD chipsets than on Intel's G45.
It's disconcerting to see the SB750 perform so poorly here.
FireWire performance, however, is equal across all thee boards, but
this has to do with the choice of add-in ASIC rather than the platform
chipsets in use.
