I saw on my local store that they're selling (very cheap) these "new?" Adata UHS-I Micro SD cards [The 8GB one is $9 USD (what would be in Mexican pesos)]. They claim that these cards are much faster than Class 10 cards (20MB/S of Read speed). However, they say they work with "compatible" devices. I'm thinking about buying 2 of those for my PSP so i can use them with my genuine CR-5400 adapter. Here's the link of the official Adata website where they talk about 'em. http://www.adata.com...&cid=7&piid=147 I've searched the whole internets, and haven't found ANYTHING about how these UHS-I cards work on PSP, anything. Do any of you guys know something about these cards?
