Pretec is calling they're 133X CF card the “world’s fastest” CompactFlash card, capable of running at up to 20MB/sec and 14MB/sec for read & write access making it 50% faster than it’s predecessor; the PRETEC 80X. Sure, but Sandisk has been pulling 20MB/sec read/write speeds for awhile now with their Extreme III CF lineup. Anyway, The 133X CF is fully ATA/True IDE compatible and operational in both 5V and 3.3V platforms. No pricing has been announced but expect this professional card to come with a professional price tag.
