Specifications (Memory Stick Pro)

Summary: By adding Memory Stick™ slots to everything they make, from camcorders to PDAs, Sony can truthfully claim tremendous market share for Memory Stick™ capable devices. Up till now, though, the format has been limited to 128 mb, which lags far behind other formats like CF and SmartMedia.

In July, Sony introduced a newer smaller memory stick, The Memory Stick Duo™, which uses an adapter to fit into the traditional size slot, but is limited to the 128 MB size. At CES this month, they've introduced two more types, Memory Stick Pro™, a true competitor to other formats with sizes up to 1 GB and the handy if somewhat comical Memory Stick™ media with Memory Select Function which allows users to toggle a switch on the back of the stick to access either of two drives on the same stick. The new formats will also be available from Lexar Media and SanDisk Corporation.
