I would like to know which are the fastest memory cards (CF and SD) that are worth buying for a 6000L. Will I see an improvement if I buy a Lexar 32X SD card (4.8MB/sec) instead of a regular Lexar SD card (150KB/sec)?

Thank you

Hi,

I've just made a couple of tests with my cards.
I have a Sandisk Ultra II 512 mb SD cards, Lexar 40x 512mb and Lexar 80x 1gb CF cards.

To test the reading speed I've created a 54mb file and put it to all the cards.
Then I was copying the file to /dev/null watching the time.

It took 64 secongs to read the 54mb file from SD card. Therefore the maximum speed for SD card is around 900 kb/s.

For CF cards it took 30 seconds to transfer the file. The same time for Lexar 40X and 80X!
So the speed would be not more than 1.9 Mb/s which is equal to ~13X .

Looks like there's no sence of having an SD card faster than 6X and CF faster than 13X.
