I have a Nikon D3000. Is there any way to speed up the continuous shooting?

I would like it if I could take pictures faster than the standard factory settings. Any help would be great!

- get a class 6 card or better
- empty and format the card regularely
- consider your AF settings, having to refocus takes time

Nope. Do you understand how a dslr works mechanically? There are moving parts that you can hear every time you release the shutter. That "clack" you hear is the mirror moving up and out of the way of the shutter, then the shutter snaps open and close and the mirror drops back into place.
All of that is mechanical movement and it can only be made to go as a certain speed.

The burst rate has virtually nothing to do with the speed of your memory card - it's mechanical.
