Thanks useful information: 
I have 2 8GB SDHC cards that I am comparing. One is a Sandisk class 6, the other is a Verbatim class 10. They both have Canon raw files on them (.cr2).
When I open the card for import (using Digikam) from my USB card reader, the first thing the app does is read/generate thumbnails so I can select which files to import. The Verbatim class 10 card is many times slower than the Sandisk class 6. Of course I expected the opposite.
Is there any possible reason, other than the Verbatim card may not be good quality? I bought the Sandisk card at Aldi, and the Verbatim at Woolworths - I would not expect either to be selling fakes.
Is there something weird about class 10 cards perhaps?
