Is there a memory stick limit for psp?

I was wondering if someone could tell me if the 8G Memory Stick Pro DUO is compatible with the PSP

My PSP is the new slim version

just wondering so if i go out an buy it i dont get bumed out when it dosent work

I agree with the above. I have both an 8gb and a 4gb, and the 4 does load faster. Its noticable, but not too big of a problem. If you like to speed through with things get the 4s, otherwise the 8 should be fine.
