This test was performed using the Sandisk Extreme card reader instead of USB 2.0 and can be different in other card readers or PC.
Consider also that do not support most cameras these high read and write speeds and therefore with two cards is hardly any difference is noted. An advantage is therefore usually has to buy card only when loading on the PC, but alone that's enough to get these super. I had to repeat the test several times because I could not believe the result. The Sandisk Extreme III writes almost as soon as they read because could not keep up the normal memory card although this is also very fast compared to other brands.
I think that one has always met with Sandisk better choice no matter which card you take. They are better alls other manufacturers in any case!
