I just got home from the mall, I was looking at the SD cards because I plan on buying a new 32GB one very soon, now here's the thing, I found one a SanDisk SD class 6 that's affordable and a Sony SD class 4 that costs 4 times Sandisk, the guy at the store said Sony is faster and lives longer despite them both being good, now I'm tempted to get the Sony one because I don't wanna have slowdowns or data loss during gameplay, I have about 30GB worth of GC games, but it's gonna take me a couple of weeks to afford this "saving up money from work", what do you suggest? shall I just go with SanDisk or get the Sony one?
