FW: [OT] Cf Card vs DiskOnChip -->CF wear levelling

[Alex Lennon]

Hi Charles,

>>I can no longer find the Sandisk reference, so I can't really support
the

the

controllers in

The SanDisk folks came back with a white-paper on wear levelling, as
relating
to life-expectancy in CF.

I've put it here, http://www.embeddedsoftware.co.uk/wearlevelling.doc,
for interest sake.

Most interestingly the text (pp2 'Analysis of host dependence') seems  to
be
saying that static data is _not_ wear levelled, which will certainly
impact
our choice of CF sizes for embedded NT and the like.

Best,

-Alex
