So, I know that the standard 8GB in the Clara HD can hold thousands of books. Which is quite a few thousand more than I currently own/have.

However, if I were so inclined, what would I look for in a memory card to make the loading/reading of ebooks faster?

I see lots of benchmarks on micro SD cards, and they have basically 6 categories : sequential read, sequential write, 512K read, 512K write, and 4k read, and 4K write.

The small 4K read/write are always slower than sequential read/write. And I wonder, with a ePub that is maybe half a MB, would the 4K read/write be an important factor?

And does anyone know if the hardware in the Kobo devices will be limiting to take advantage of a $50 top-speed card?
