Submission Pre-erase SD Cards for Better Performance 1

Nom du Keyboard writes: I'm wondering if it is possible to pre-erase my SDHC card for my camera for better performance? At the moment in continuous shooting mode I can shoot 3 fps for the first 3 seconds in raw mode (9 images total) after which the rate drops to 1/fps until the SanDisk Extreme III goes full, or my battery goes empty. Can I improve my write speed by pre-erasing the card so that the flash memory doesn't need to perform a block erase before writing, and if so, then how? I don't believe that the Format command in the camera does this because it competes very quickly each time I use it. I'm surprised that more isn't said about erasing flash memory on file deletions for better write performance later.

    Pretty sure flash drives don't work that way. It just writes over empty space whether it's been "erased" or not. I would guess that your camera has a buffer that fills up after 9 frames, and the speed drop has nothing to do with the SD card.
