I am sure it could be done that way, but you still would come across the 
bottleneck of the drive, in this case, so a lot of that performance 
would be idle waiting on the disks, unless you had your disks laid out 
by partition, something like / on sda1 /boot on sda2 /usr/local on sdb1 
/usr/share on sdc1, /var on sdd1, etc. then you would have slightly less 
I/o wait unless your controller didn't like writing to multiple buses at 
once (some crappy SATA hardware has this problem, like the Lanparty 3200 
board from DFI) or old IDE.
