Take care that I have done from Internet sources, I am not responsible of the data showed before, It's only sharing information. Those are my conclusions:
16GB:After analyzing the scores (Read1+Read2+Write1+Write2)/Price, we take care that a 16 GB is the best one (Patriot 8GB can be the first one), and as you see it has a really interesting price. As you see the OCZ Rally2 16GB has the half speed on writing so there is no doubt.
32GB:About 32GB now OCZ wins, I am not sure why the writing speed vs the 16GB is so huge. Of course I haven't the flash drives to test them, but the technology could have changed. In case of doubt, followint this is Patriot again.
08GB:In the 8GB flash drives, I am sure that Patriot wins, then Corsair Survivor GT (may be the Voyager GT too), and after the Sandisk, which is not typical in this kind of charts. Well, I hope the analysis helps you because now I know that I have to buy the Patriot 16GB, because 8GB could be little today.
