md/raid5 uses a LOT of cpu. That would certainly explain why it takes a lot of cpu to access those drives. I would call that perfectly expected bahaviour. If you want low cpu use, stick to raid1 or use a hardware raid controller (like the 3ware or areca). Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
