Sony 4GB Memory Stick - PRO Duo Card - MSMT4GN

Product Information

The Memory Stick PRO Duo (MSPD) quickly replaced the Memory Stick Duo due to the Duo's size limitation of 128 MB and slow transfer speed. In response to the storage limitations of the original Memory Stick, Sony introduced the Memory Stick Select at CES 2003 on January 9. With these cards you can increase your storage capacity just by replacing the original card with one of a higher capacity.

This one probably does not do SDHC but you probably have something for that already in case you need it. These cards allow you to manage the memory on your phone backup the contents protect from theft loss or damage.On January 7, 2009, SanDisk and Sony announced the Memory Stick XC format (tentatively named "Memory Stick Format Series for Extended High Capacity" at the time). In spring 2001, Memory Stick attained 25% market share (against CompactFlash's 40% and SmartMedia's 32%), up from 7% a year earlier.
