Everyone who owns a PSP knows that the 32 MB memory stick included in the basic PSP pack is not really cutting it if you want to take full advantage of Sony’s handheld console. If you like to use your PSP for anything more than just playing games, sooner or later you will have to buy a memory stick with bigger storage capabilities.

SanDisk has already been selling 256 MB, 512 MG, 1 and 2 GB Memory sticks for a while and has now launched the Memory Stick Pro Duo with a 4 GB capacity available at several stores for around $200.

In July SanDisk will launch the Rapid GX Memory Stick Pro Duo, which will allow you to transfer data to and from the PSP a lot faster. According to this Gamespot review about PSP accessories, the first Rapid GX card will be available in July and will have 1 GB storage.
