32GB MS Pro Duo, July 29, 2009

I bought one with two 8GB microSD cards. In my fat PSP it shows up as a single 16B stick. It's a little under 16GB but that is normal considering overhead. I fit over 40 games on a single stick! No more carrying around half a dozen sticks. Get one, they're great.

I decided to go this route after getting burned on two different Memory Stick Pro Duo's on a popular auction site. I was skeptical, but based on what I read on the Sony forums, this should work fine with my PSP. They were correct!I also bought 2 which got me just over 14 GB of usable space for games, music and movies on my PSP. Plus, I should be able to upgrade to 32GB once the 16GB microSD's drop in price.Overall, with memory prices as volatile as they are, you will have a hard time finding a more flexible and affordable Memory Stick Pro Duo option out there.***Just remember to format the cards in your PSP and not your computer/laptop.***

I used 2 SanDisk 16gb Class two MicroSDHC cards, and now have 32GB of space on my PSP.Games run smooth off the stick.I couldn't be happier.
