Adapter

The Memory Stick Duo adapter allows you to use Memory Stick Duo cards in devices that support Memory Stick (Standard). The adapter allows you to use the new MS PRO, MS Duo and MS PRO Duo cards in devices that only support standard Memory Sticks.
The new Memory Stick Duo and Memory Stick PRO Duo cards come with an Adapter that allows you to use Duo cards (Short) with devices that are ready for Memory Stick (Long). Similarly, there are two adapters for M2 cards, one for the Duo format and the other for the Memory Stick.
Please note that adapters are only used to fit the physical card to the device. They do not guarantee that the device in the old Memory Stick format will support the new cards. This is due to the fact that old devices (and these mainly use "long cards") often have limitations as to maximum capacity and speed.
