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? -- Jon -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
