I've heard that compact flash readers allow your computer to much faster read the photos off the camera, than when you connect your camera over USB.
Is that true? What about other card formats, like SD?
Answer
It depends.
My last camera only connected at USB1.1 speeds, so was slower than using a USB2.0 card reader.
However, if your camera can do USB2.0 or you have a USB1.1 or USB1.0 card reader, you wont see that benefit.
You can get Firewire or ExpressCard card readers for CF cards, which are faster than USB2.0, (and I think generally limited by the speed of the CF card). Sandisk do the fastest of these - see Extreme Firewire Reader and Extreme Pro ExpressCard Adapter.
Of course with USB3.0 devices beginning to appear, these are (theoretically) faster still than Firewire - but you need a machine that supports them (rather than running in USB2.0 backwards compatibility mode) to benefit from this speed.
