A question cf card writing time

[jockwav]

Never thought about this until now,i was just messing about out the back taking some long exposure shots on bulb mode.
Thought i would try some firework shots,the thing i find is it seems to take time to write to the cf card,is there any way you can speed this up?.:shrug:

If you have long exposure noise reduction turned on it will double the write time. It takes another picture with the shutter closed using the same exposure time as the original, to use as a reference. It then writes this to the card as well.

I don't think the dark frame is written to the card. The acquired data is subtracted from the actual image and the result is written to the card.
