I'm finally looking into given my PSP more memory and i'm seeing a couple ways to do it. As far as I can tell, aside from the rumored memory stick XC, the largest amount of space to put into these PSP's is 32GB. And can be achieved with your standard memory stick, or a sd card adaptor.

however i'm concerned with speed and i don't mind spending a little more for a setup that would be optimal. The memory stick info on wikipedia is a good wealth of info however i can seem to find transfer speeds on these adaptors. I'm assuming the speeds that these adaptors reach is the same for the format that they say on them. Like a memory stick pro duo and a memory stick pro duo adaptor should have same speed right?

And for use with the PSP, is there a noticable difference between pro duo and pro-HG Duo that you guys notice? And if so in what area's, like game load time, transferspeed between computer, ect...

And if someone can link me some great deals that would be nice too...
