This comparison for example suggests that class 4 scandisk and silicon power cards are up to 100x faster than patriot class 10 cards for some small random write operations:

Ahh, yes. Of course. I'm silly.

Then I'd recommend following your own reasoning and go with the benchmarks, looking for good random read/write speeds ^.^

As I said earlier, I haven't noticed any difference between the Class 10 Patriot card I have now and the Class 4 SanDisk card I had earlier though.

WOW though. Those Class 4 cards make a HUGE difference in the random write tests.
