The main idea seems to be that class 6 and 10 cards have been optimised for large sequential read/write operations at the expense of small random read/writes, but much operating system performance depends on small random writes (such as updating the KoboReader sqlite database).

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:
