Well, high speed is relative. Some are faster than others. Rob Galbraith's database tests the actual cards to let you know exactly what you're paying for. Just like processors, I like to buy one or two steps below top of the line - it's not worth paying twice as much for that extra 50kb a seccond.

I hope you needed it that day. Accessory items are the worst thing to buy at best buy.
