PCI-X is a parallel bus at 100 or 133mhz PCI-Express is a newer serialized
bus with the capabilities of bonding more channels. It comes in the
following flavors 1x, 2x, 4x, 8x, 16x, 32x, and 64x. In testing Raid on
ROMB devices we found large increases in performance using PCI-Express
over older technologies.
