In response to the storage limitations of the original Memory Stick, Sony introduced the Memory Stick Select at CES 2003 on January 9. The Memory Stick Select contained two separate 128 MB partitions which the user could switch between using a physical switch on the card. This solution was fairly unpopular, but it did give users of older Memory Stick devices more capacity. Its physical size remained the same as the original Memory Stick.
