There's a good balance to be struck between the performance of SCSI and 
the price of IDE by buying a cheap ATA100 or ATA133 PCI card and popping 
it in the U10. Boot off whatever little IDE disk comes to hand from the 
onboard interface then put all your access-time sensitive data on big 
(relatively)fast IDE disk on the PCI controller. My Ultra10 currently 
boots off the 9GB IDE that came with it originally, this disk onyl has 
/, /boot and /var on it, everything else is then mounted from a 120GB 
disk hanging off a 20UKP Promise IDE controller.
