"RAID 0 offer similar performance when using a hardware RAID controller. The CRC calculations are done by the controller"
Just be aware that the "cheap" HW RAID controllers these days aren't really HW RAID controllers at all.
All they are are IDE controllers with a bit of POST boot ROM to allow them to create an RAID 0 or 1 or 1 + 0 array, and boot off of either disk, in the case of a RAID 1 array, in the case where one has failed.
Once the OS is loaded, the device driver (and therefore the CPU), is doing all the RAID stuff.
