as big as they will make them. if ur getting a big one tho(16gb+) i suggest a photofast cr-5400 (its a dual microsd to ms converter) and 2x 16gb or 8gb micro sd's. its the cheapist way to get 16-32gb on ur psp. http://www.dealextreme.com/details.dx/sku.16489

i have a cr-3100 and 2 16gb SD's and love it

i using an 8gb on 5.00 m33-6
it works fine

BUT
psn/ps3 cant see the full 8gb

it might be. it might also be a fake. where did u get it?

im loving my sd cards. i got 2x 16GB in it right now but the psp shows and uses 29GB. only speed problem there is is that it takes a extra second or 2 to load the xmb from a cold boot. as for read/write speed's compare ur current card to these using black speed (link in the link) http://www.psp-hacks.com/forums/f117/cr … s-t234571/ (im koukimonster there) and yes it shows the 2 cards as one


edit: also the quickist way to tell if ur card is fake is to hit triangle on it in the psp xmb then go to info and if it says any thing but supported beside magicgate then its fake. unless its one of these adapters

i dont think so cause u can see all the free space when its on a comp. i think its just the psp

I'm pretty sure the most is 16GB.

I thought I commented already, but...  From what I read, OE firmware 2.81 increased it to 4GB.  It's the custom firmware that allows a LOT more.   Sony brought out a 16GB Duo Pro, so not sure on the OE firmware's limits, which is said to be NONE; who knows...

I have three memory stick micro M2's, of which I only used one but I have the space if need be.
