If you want something done right, you'd better do it yourself. That's SanDisk's thinking anyways, with their new RapidGX Memory Stick PRO Duo cards they're showing at E3. The cards do the usual Memory Stick PRO Duo thing, namely providing music, movies and other content for PSP owners, but they include a bit of SanDisk special sauce performance enhancements to speed file transfers up to 15MB per second, double the normal rates for PRO Duo cards. Seems like they just got tired of Sony's limitations in the Memory Stick tech, and figured a way to improve it themselves. The 1GB card is all that's available right now, and it retails for $85. The price -- for a limited time only -- includes for free SanDisk's new MicroMate high-speed card reader to help the RapidGX hit its maximum speeds, and also includes PSP loader software to maximize space and convert files.
