Ypu, and if you want the best of all words, you need RAID 0+1, which is complete overkill for home use, I'd say....

There are also some cheapish hardware IDE RAID cards around now, never tried them out, but should be significantly better than Software RAID (which in my experience is flaky and terribly slow).

Personally, I would never have a RAID0 installation at home without some serious backup hardware (DLT minimum). Reason being you are more exposed to risk of loss of data with RAID0 than any other RAID system.
