I want to connect a webcam to a pendrive

I want to connect a webcam to a pendrive. Can I use an arduino board?
I want to record video from a webcam on a pendrive without using a computer.
is there any arduino board that can do that?
If not, can someone help me do it?
Thanks, Alex

Well the arduino has not a native USB master mode. Using some plugin board you can have a master USB but it interfaces throught SPI. SPI is far from the speed you need to handle a video stream.

Look at this product:-

Check it can transfer data at the rate you want. I doubt it.
