do the cdj2000's support 45mb's a second uploads, from sandisk extreme pro cards?

ok the shipment has left, so now i its too late cancel. fingers crossed the sandisck "extreme pro" cards can reach their full potential with the cdj's :)

Even at 20MB/s, that's more than 4 streams of a 24bit/96kHz WAV source.

so your answer is that the cdj 2000's software maxes at 20mb's? and getting a 45mb/s card is not advantageous? please advice.

There's a difference between a card's read and write speeds.  If you're writing to the card, that's where you want it to be fast (especially for guys taking HD video).  As a DJ using the SD card, you'll find it most advantageous to have a high-speed card for storing tracks on the device; when you export from Rekordbox, you'll have a lower export time.

The read speed, even if it were 20MB, is much higher than the maximum amount of data draw anyhow.  The max is four streams of 24bit/96kHz which is just about 2.2MB/s total.

Christian, im very curious if you had any problems witn the SanDisk SDHC 16GB Extreme Pro USH-1? Can you leave a reply, I'm interested in ordering the exact same SD cards.

Thanks!
