Now which bus is faster: 64Bit PCI-X at 133 Mhz, or a PCI-E 16x?
The x16 PCI-E has considerably faster theoretical speed than 133 PCI-X (appx. 4GBs vs. 1GBs). However, the RAID controllers that I've seen are at most x8 so they are only capable of transfer rates half that fast (2GBs). Personally, I would go with PCI-E since in some performance tests I did with Areca cards last year (both PCI-E and PCI-X) there appeared to be a slight performance advantage to the PCI-E cards (sorry, I don't recall any of the specifics anymore, so please take that for what it's worth). BTW, I've had good experience with the Areca cards in FreeBSD (recent stable).
