Thanks Ket. That Rocketraid card, the 2640x4, caught my attention because it was not very expensive. Sub $100 if I remember correctly. However, I decided to pass because one cannot specify the stripe size on a stripe array. That was my reasoning for wanting a seperate raid card. I wonder if it's more the card itself than the P67 chipset or E4 board. Unfortunately, I don't have a raid card to test.
