* To achieve maximum throughput in the 2008 Mac Pro, one or two of the PCIe 2.0 x16 slots must be used. These models have two x16 PCIe 2.0 slots and two x4 PCIe 1.0 slots. The latter PCIe 1.0 slots will only allow up to 585-753MB/s data transfer rates.
** From the review at barefeats.com: "Using the 'Expansion Slot Utility' in the System/Library/CoreServices folder, we reconfigured the PCIe slot speeds to various combinations of 4, 8, and 16 lane slots to benchmark the XP941. The transfer speeds above were achieved using the 4 lane slots. The 8 lane and 16 lane slots did not produce any faster transfer speeds. On other other hand, if you use a 1 lane slot, the transfer speeds drop to 200MB/s READ and 170MB/s WRITE. We tested with both OS X Leopard and Snow Leopard. OS X Tiger kernel panicked at startup. Though we didn't try it, it should also work with OS X Lion, the last Mac OS to be officially supported on the 2006 Mac Pro."
*** To achieve the listed throughput rates on a PC/Workstations/Server platform, a PCIe 2.0 x4 or higher slot is required (e.g. PCIe 2.0 x8 or PCIe 2.0 x16). PCIe 1.0 slots may provide lower performance, depending on the number of PCIe lanes allocated to the slot.
