I wanted to buy the PlayStation Network a few PSOne classic games, in order to play this move. This was my previous memory card too small. Since I've had good experience with SanDisk, I again bought a model of this brand. This turned out to be a bad investment. Although the card works in principle in my PSP, that you will be recognized and you can work with it. The map, however, is far too slow. In Final Fantasy VII for example, remains the game constantly hanging and asks if you want to quit. Except for games I use my PSP as an MP3 player to listen to audiobooks to go. Again, the data is coming far too slowly on the map. The PSP then stops playback and moves to the next track. At the files it can not lie, because I have these times copied to another memory card, and from this they can be played properly. My conclusion for PSP owners: Stay away from this card!
