Is PCIe the bottleneck? I suppose it depends on the number of lanes. PCI 3 can run at 1GB/lane, so a 16 lane slot could handle 16GB/s, theoretically. I think the limit on OWC's product is the number of SSD's on the board more so than PCI (the card uses 4 SSD's to deliver 6GB/s, so I suspect that is really the max number of SSD's). It appears that OWC is using an 8 lane card, but multiple cards can be pared together in RAID for even faster performance (12GB/s x 2 cards—yikes).
Maybe?
Either way, 6GB/s is approaching RAM speeds from not very long ago.
Update: Actually, OWC is using a x4 slot, so that's weird that they are getting 6GB/s.
