I'm gonna try that out. I'm also paranoid. (but seems like you beat me hands down.

It just Definately. And since you're running on 7200rpm Drives, it's way better than my 5400. Depending on the location of your drives, don't it becomes unbearably hot??

In single key mode, it runs at about 110-120MB/sec (I had to I'll have to see how it fares for me.
