Memory Stick

Memory Stick is a type of flash memory developed by Sony. It is used to store data for digital cameras, camcorders, and other kinds of electronics. Because Memory Stick is a proprietary Sony product, it is used by nearly all of Sony's products that use flash media. Unfortunately, this also means Memory Stick cards are incompatible with most products not developed by Sony.

Memory Stick cards are available in two versions: Memory Stick PRO and Memory Stick PRO Duo. Memory Stick PRO cards are 50mm long by 21.5mm wide and are 2.8mm thick. Memory Stick PRO Duo cards are 31mm long by 20mm wide and are only 1.6mm thick. High-speed versions of Memory Stick media support data transfer rates up to 80Mbps, or 10 MB/sec, which is fast enough to record high-quality digital video.
