So I've had my SCDS1 for a good month or so now, and originally went with a 8gb class 4 kingston japan figuring it would run flawless just because its kingston, but realize now that I need a faster card because of slow FPS at certain points in game which is really annoying, and the occasional freezing not to mention gui sluggishness. Ive been reading that A-Data 4/8GB class 6 and 1-2GB Kingstons are the best when it comes to random access times. Im wondering if there is a big speed difference between say a 4gb adata and a 1-2gb kingston? Also would a 4gb A-Data be faster than an 8gb, both class 6? Or do both of these have the same performance?
