I hope these 12 gig cards have some blinding fast transfer rates!
at 6mb/Sec of the average USB 2.0 CF card reader it would take 33
minutes to complete a transfer! Yikes! Better not even attempt it
with USB 1... it would take over 3 hours!

Actually, in an embedded system, you connect the cards to an ATA
port (just like inside the camera) not a USB port.

So, you're talking about 12 meg/sec (80x) cards. The configuration
I described put 4 cards in a raid 5. Four cards are transfering
data simultaneously, 25% of the data is striped error correction
codes, so that gives you 36 megabytes/sec, sustained.

With zero seek time.

Although one typically doesn't run into an embedded system that
needs 36 megabytes/sec.
