Crystal DiskMark said it was much faster (1.81MB/s vs 0.019MB/s)* than the Kingston on small block random writes and 1.5x (3.1MB/s vs 2.03MB/s) faster on small block random reads. With that card, the Kobo is back to what seems to me to be the same speed as the original 2GB card.
* I ran the write test 4 times before I accepted the results. 95x was hard to believe.
Makes sense in a way since the original thread where I ran into the discussion of SD card speeds was installing CyanogenMod 7 on a Nook booting from the external SD card slot.

Hmm good information. I did some looking and noticed that even though cards may be class 10, there is a long gap between speeds in Class 10 cards. Varying as you suggested to some extremes where the Class 10 cards barely make the min specs. And there are a lot of class 10 cards making high claims in speed but failing to achieve them. That said I am sure the different card readers and devices have certain limitations on them and I am sure the Kobo devices are no different. And to be fair I wonder what specific cards work best for the Kobo. Thanks for your insight btw.
