Troll ?
Have you tried sustaining 20MB throughput on "low-end" hardware ? Not SCSI but IDE.
Hint, typical quotes of IDE throghput are really potential burst rates.
The IDE problems are only magnified with more drives on a controller. The IDE bus is locked untill every time consuming request (seek/write/read) is complete. IO throughput cant be completed in parallel.
PCI with six MPEG compression devices, even performing DMA, will have a tough time. This is more of TDMA problem that PCI cant be guaranteed as a solution.
BTW, which OS was going to do this with no problem at all ?
Not to be difficult, in theory could work but I have found off-the-shelf hardware/software are 1 or 2 steps away.
