mxi express and PXI-8351 benchmarks

[mhfracis]

The following post discusses speed tests using a pxi express system both writing to memory and to disk.

I'm interested in testing a PXI-8351 Rack-mount Controller instead of the embedded controller I assume they used in the benchmarks.  This controller has a PCIe x4 slot, so I should be able to use the PCIe8371 x4 MXI card.  Does this mean I could expect the PXI-8351 to write 800MB/s to memory? (assuming I could transmit that rate)  Will the motherboard chipset ever be a limiting factor in this experiment?

They also speak of PXIe and ExpressCard raid arrays.  I can't find either of these if they exist.

Hey MhFracis,

I think your chassis would also play a role in the communication speed. What chassis do you plan on using, and how many DAQ cards?
