Don't want to risk it before that.
Once I have accessed the book from the SD card the first time, I don't notice any slowness. The first time, the Kobo generates the 3 images on the fly which takes a bit longer. The newest firmware seems to be storing those images on the SD card so next time I factory reset, I hope not to notice that slowness on the first opening or displaying on the carousel.

One note is that the card I'm using in my uSD card slot was picked as the best of the cards I owned in the small read/write test using Crystal DiskMark. See an earlier post in this thread with two images of just how different SD card results can be. What my experience indicates is that the class of the SD card is a useless item as very often the higher speed cards have pathetic small block performance. A Lexar Class 10 card from a digital camera gave me the results in the image below. I worked great in the camera where 6-8MB files were being written. In a Touch, it was pathetic.
