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.

This is great information!

I've been meaning to use pages like this:
XDA Forum post

I want to acquire the fastest one I can find. I don't necessarily mind the wait time, but it would be very nice if it didn't exist or was minimized.

I think I wouldn't care at ALL if the Kobo had an open directly to my page from powered off setting.
