Actually no. We did a comparison with three discs on a (adaptec) SCSI 
160 in raid 0, software raid 0 on the same controller (same discs) but 
just in plain SCSI and, for a bit of fun, raid 0 on three random (but 
reasonably quick) IDE drives connected to the two IDE ports of the same 
Dell server.

IIRC the results were:  software raid in SCSI nearly 5 times as fast, 
ditto IDE 2.5 times as fast as the adaptec doing its hardware raid 0.
