Well, that's true. However, perhaps I mis-spoke. What I was intending
on doing is showing that the chipset was /not/ the limiting factor
here, not checking it's maximum speed, but rather given what I know
about the drives individually, and then what the rates are with all
drives cookin', then I can say, "Well, at least the chipset or bus
aren't getting in the way." Note that I also added "or bus" to my
statement. Would you say that this statement is more accurate or am I
getting the terminology wrong, again?
