Tony, yes my plan is to have two hard drives to have more perfomance
( than one ) and I will try them with the on-board controller. This
afternoon I read ( forgot to save the URL ) an article with benchmark
comparing raid 0 with more than 2 drives and I feel impressive with the
increased performance with 4 drives. If the 2-drive configuration is too
slow in compare with my current scsi-raid0-4-drive, then I will have to
use an pci-e that supports 4 drives and try it also.
