[quote name='sotc1988']I like this one off newegg for $20 each. It's a 32 GB micro SDHC card and has a class 4 write speed. That might be slower than you'd want but it will read files just as fast as a class 10 card. Get two of them and bam, 64 GB of storage for a hell of a lot cheaper than sony ever intended.
32 GB Micro SDHC
You can use this adapter once you get two of the cards. *LINK REMOVED*
It's about $5 more than some of the other adapter's off amazon, but the reviews were pretty mixed on the cheap ones.
Edit: Hmmm. I may need to read up on this more. There does seem to be some arguing about whether 64 gb is supported and if so, it may need a specific adapter and not the one I linked. Some caution is needed I guess.
Edit 2: Okay, so don't use the adapter I listed. Use this one off of amazon instead. From everything I've read, there are confirmed reports of getting 64gb of storage using this adapter and two 32gb micro sdhc cards.
PhotoFast CR-5400 Also, this may only work if you have cfw on your psp but I'm not 100% sure. Either way, you should always have cfw (cfw does not equal pirating).[/QUOTE]
Those reports have to be false as items that can read the "high capacity" level of memory cards are limited to 32gb due to hardware addressing limitations.
also if you buy a photofast cr5400, be sure to research what a real one looks like as there are alot of fakes out there that get really hot and melt in your system.
I also own that one from ebay (I actually got it from that seller) and it does support one 32gb card in slot one just like the cr5400. so far ive had no hiccups with it, but i do suggest you buy class 6 or higher memory to put in it. class 4 works, but is a little slow...
