Intersting link to the chart there. Doesn't it seem odd that the same brand and speed card at different capacities comes up with different speeds? With everything else being equal going from a 16 gb card to a 8 gb card should produce very similar read/write speeds.

depending on the vintage and the prices of chips at the time, you may have different density memory within the flash cards, and that can have a very big affect on performance. Also seen with USB flash drives - the higher capacity ones tended to be slower.

On SSDs, the higher capacity (240G and up) tend to have more data paths then the smaller ones, thus much higher performance.
