usb flash stick is probably the easiest and fastest. Just copy the files over and you've got it done.

Doesn't a webcam come with a SD flash card? I pull my SD card out of my camera and load it onto my computer first. Then transfer pictures and videos to USB like dolphin_oracle says if my wife wants the pictures and videos on her Windows Boxes.

OOps, I must be tired. __{{emoticon}}__ Webcam is not a video camera. So one step less. Just transfer video to usb flash then. If wanting to back up a lot of videos. Then a external hard drive like a passport or similiar small unit would be in order.
