SanDisk Corporation today introduced a new 4-gigabyte (GB) capacity, the highest available in the market right now, for its standard Memory Stick PRO Duo cards. When inserted into an adapter that converts the Memory Stick PRO Duo to a Memory Stick PRO format, the card also can be used in any device that hosts a Memory Stick PRO flash card, including card readers, personal computers, television sets and some DVD players equipped with flash card slots.

The newest capacity of 4 gigabytes joins other capacities in SanDisk's standard line, which includes 256 megabytes (MB), 512MB, 1GB and 2GB.  Suggested retail prices range from $34.99 for the 256MB card to $299 for the 4GB card.  The card is expected to ship in April.

SanDisk also is making a color change for its Memory Stick PRO Duo line, from pale blue to deep blue. This gives the cards "a bolder, brighter look that makes them stand out", said Park. Sony and SanDisk co-developed the Memory Stick PRO media format, and SanDisk manufactures its own Memory Stick PRO Duo cards.
