The fastest SD card in the industry - not!


So when I heard a tagline like that, I had to test it. I ordered a Sandisk Extreme Pro SD card, and tested it in an Apple MacBook Pro, which I thought would have no interface or bus-related speed limits.


I also tested it against their Ultra and their Extreme cards. The summary of results is that there is a 1Mb/s difference (17Mb/s vs 16Mb/s) between the top end card (~R900), and the bottom end card (~R450).


Conclusion: its not worth paying more money for these "faster" SD cards. For double the money, I want to see more than 6% performance difference. Pfffft.
