Memory Stick® PRO Duo™
The Memory Stick PRO Duo media provides storage for your portable digital device, such as compact digital camera, camcorder, or audio player. At just half the size of a standard Memory Stick PRO media, it still offers the same technologies, including high capacities and high-speed data transfer. The PRO Duo card is backward-compatible with devices that use Memory Stick PRO Duo media, and with an adapter (not included), it can be used in all PRO-compatible devices.
Memory Stick PRO Duo cards weigh just less than an ounce (2 grams) and are about the size of a postage stamp.
1 gigabyte (GB) = 1 billion bytes. Total accessible capacity varies depending on operating environment.
