I have an adapter to use microSD in PSP(microSD to memory-stick pro duo).
I need to buy 16GB memory card.
Now should I buy a microSDHC card or memory-stick pro duo.
memory-stick pro duo is costly but the speeds are high compared to microSDHC cards from what I heard.
What are problems that I may face if I use microSD card?

And also fake MS card is available for the same price of a legitimate microSDHC card with warranty.My friend has been using a fake MS card for past one year and hasn't faced any problem till now.
Can somebody suggest what I should buy?
