Comment:
We should add your test program to the SD card qualification process along
with the SD wear leveling testing.
I'm not happy with the performance of the Class 2 SD cards, but they
generally perform better than JFFS2 on the XO-1, and without loading the
processor.
This is probably improved on Class 6 cards, but there is strong pressure
on the laptop price right now, and we can't afford the extra couple of
dollars.
