I've actually had very good luck with both the 7006-2 and 8006-2, both of which only do RAID 1 and 0. I've only had to rebuild once with the 7006, and I didn't notice a performance hit during the rebuild process. The main reason I recommend and use 3ware over Adaptec is the excellent driver support and the administration utilities that are available (both CLI and web-based). Mike
