Axtremex Technology has announced a new CompactFlash card with an 800x speed rating, claiming 120MB/s read speeds and 95MB/s write speeds. The card is UDMA Mode 7 compatible and runs $400 for a 128GB capacity.
Note that even faster speeds have been attained my mainstream manufacturers (see the 1000x Lexar CF card for 150MB/s read speeds); however, prices are much higher.
