Looking at Intel's specs on the X25-E, it appears that the total
cache on it is 16mb. Is that all that would be vulnerable if power
was lost, or is it worse than that?
Only Intel (and perhaps some people under NDA) know the answer.
A write to a FLASH device requires that either existing data be moved,
or that existing data be re-written in place. This is because FLASH
data is managed in large blocks, and a block needs to be erased before
it can be written. An updated block needs to be updated in device RAM
before it can be written. Without an exceedingly good design, this
makes me feel nervous if the power fails since data unrelated to the
write could be destroyed.
