I have an M3i Zero and a SanDisk 16GB class 2 card. It works great for the most part, except where it freezes in some games like TWEWY (during the opening movie) or in other games like Tales Of Innocence (a bit laggy when loading up a battle scene or an important event), and the Castlevania games. Sandisks are an overall good investment in micro SD cards but the downside is that they are on the expensive side. I'm looking into getting an 8GB class 6 card that's less than $25 and I've managed to narrow it down to these brands: Transcend, Adata, and PQI. Which is the best card for me to get that will be fast enough to allow me to play these games smoothly and where can I buy it?
