1x = 150KB/s
UltraII has 9MB/s write speed mean it have around 60X
Extreme3 (the new extreme) has 20MB/s mean it have around 133X
Lexar has 80x and 40x mean it have around 12MB/s and 6MB/s
but as i know the fastest card reader Cardbus and IEEE1394 only can write at a max speed of 6MB/s (40X)
so why do we need anything more then 40X ???
why would ppl spend so much on a ultra high speed card ???
they have too much money to spend or i miss out anything here ???
