Depends on how fast the SCSI disks are. If you stripe them together, you'll probably get just under 2x the speed of a single one (I get about 1.7x on a very old PS/2 with equally ancient disks, using the kernel's built-in RAID drivers, but with a fast CPU and a decent SCSI adaptor you may well get better results). [I imagine you're thinking of making a RAID-1 (stripe) array from the two SCSI disks, then adding this to the IDE one as a linear array.] Stephen ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The debugger for complex code.
