Coincidentally, the Slovenian website eFotoGrafija have also published a comparative review of high-speed memory cards, this time Compact Flash, testing them in conjunction with the Canon EOS 1D Mk II digital SLR. The 100x speed Apacer Photo STENO ProII card is one of the 5 cards in the test.

“Manufacturers mark speed with X values, which indicates the speed 150KB/s. The larger the number in front of X, the faster the transfer rate should be. Few years old memory cards have 4x or 8x transfer rates and many new cards still maintain this speed. This is perfectly acceptable for average users shooting family or travel photos, where read and write speed are not so crucial. However when using cameras with more million pixels, more frames per second and longer video clips, we encounter first troubles. This is the moment when we need to consider faster memory cards.”
