This memory card is a must in order for to save your game data. Make sure if you get a memory card , get this one , no second or third party memory card. I've done that before and after 4 months my memory card stopped working. The Sony memory card may cost a little more but it's better than buying cheap memory cards that don't last you along time. Once I got this memory card it's been working for about 6 months now. Be smart get this one.
