stupid question but is the 133mb/s bandwith for the entire pci bus, or per slot? If the later could I double my total HD bandwidth by splitting my drives into two smaller raids instead of a single large one. I know it would be a limited gain since I'd only see the gain when accessing two files on seperate arrays. Anyway I'm just wondering if this's a potential option or would only end up eating a cardslot.

Sadly, that 133 MB/s bandwidth is for the entire PCI bus.

Which is realistically limitted to about 120MB/s after overhead and such.
