Flash Memory Cards - Sony Pro Duo
Sony Pro Duo cards are longer than the rest and are used in Sony devices such as the Sony PSP hand held games console and camcorders.
Pro Duo cards are available as single cards but are generally more expensive than the new micro SD to Pro Duo types. These simply utilize cheaper Micro Secure Digital memory cards which fit into a dummy Pro Duo adapter, allowing the Micro SD card to be compatible with any Pro Duo device.
These cards are also able to be placed into a card reader so that any data stored on the card can be transferred to the computer.
While capacities range upwards of 8GB, older devices are unable to support such a large amount of storage so please refer to the user manual for the maximum storage capacity.
