Thinking about getting a Pi. I have a old Sony PSP .Can I use the Pro duo for the PI.Or do I have to buy another sd card??

That's not an sdcard, so you won't be able to use it.

So I need something like this??

[popcornmix]

That should be fine.

You may get better performance with something like this,
but if you already have the Kingston card, then give it a try.
