PIO and RAID?

I was thinking of stringing together a couple of Sandisk Ultra II cards in RAID0 for a fast access system drive for a system drive and I was wondering if it was possible to get PIO devices (Compact flash cards with IDE adapters) into a RAID formation that would allow DMA on the array. Thanks, all.
 
Up to the controller, I would think. You'd lose any STR benefits of RAID, though, since PIO is so slow compared to DMA. But if your objective is just a 'big' CF drive, it might work... no idea which controllers might support PIO devices, though.
 
Just in case you hadn't realized it, having the operating system swapfile and temp folder on a flash memory drive can drastically reduce its lifespan.
 
I plan to de-activate the swapfile for this particular system, which has enough RAM.

But I think a RAIDed flash array is a very novel idea, as you can get 4 or so GB of very fast storage. 0.3ms seek time and 100+MB/s depending on how many cards you use.
