Yes - if you want to do RAID relying on the Promise driver (no 
updates/bug-fixes, etc.). I'd rather do ATA RAID as supported by the RH 
driver instead.

The RAID native to the Promise controller is described in the ATA RAID 
HOWTO as "fake Hardware RAID... ...using SCSI Emulation", and I'd rather 
get rid of the CPU overhead that this apparently incurs. But I do 
appreciate the suggestion.  :-)
