SanDisk RapidGX Memory Stick PRO Duo cards trump Sony

Via Engadget

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.

Make a 4.0GB RapidGX and you have me sold.

Can you reach the 15MBs/sec rate through the PSP as well, or it´s just through the high speed card reader?

If it´s only through the reader it´s going to be a pain in the arse having to removee the memory stick from the PSP everytime you need to write something on it.

will be same speeds on psp and you need their hardware to make any differerence when using it on your computer.

if theres an 8GB i will die for it XD

Is there a reason to have higherspeed? Other than transferring the files faster, are there any other advantages?
