from PCI framegrabber to PCI raid


I have an IDE RAID which is connected via the PCI bus.
I have also 2 framegrabbers. I'd like to capture real time video (2 x
27Mb/s) to my RAID (max transferrate ~ 70 MB/s).

I haven't tried it yet. But I suppose it should work.

Is it however possible to move the video stream directly to the raid
without passing the system memory ?
Because if you use the PCI bus to pass the RAM and vice versa than the
bandwith of the PCI bus is divided in half.

Best Regards,
