You can also use File Sharing to copy documents from the iPad or iPhone to a PC or Mac.

File transfers generally run pretty quickly, as USB 2.0 can handle up to 480 megabits per second (Mbps)–but if you’re transferring many large files, it’ll take a while. And if you’re using a USB 1.x port, its 12 Mbps limit will make things much slower.
