Another very important fact about Flash cards is that they wear out.
Most are rated at between 100,000 and 200,000 writes on any given
sector. A sector is 64k. Sundisk estimates that with their wear
program that is 5-10 years use for the average user. The manual says
that the wear program increases the life of the card many times. It
also says that the wear program only works on a 100lx or HP Omnibook.
I use mine for my 100lx so that's no problem for me. Others with
flash cards might want to consider buying an occasional lunch for us
100lx owners. Of course we'll be glad to wearlevel your cards for you.

One more important fact about Flash cards is that when writing, they
use huge amounts of power. They use about as much as an sram card when
reading and none at all when not being accessed. The sram card uses its
battery when the computer is turned off.

The result of this is that if you do a lot of writing, you're gonna cut
your battery life a lot. Also when your batteries get down to the last
1/4 or 1/5 or 1/6 of their life, you can get a low battery indication
from doing a write. I've been told that the card won't corrupt a sector
when this happens.
