Given that a lot of hardware is now coming with SSDs, and we all know
Windows will wear one of those little buggers out faster than anything
else, is it (already) possible to set options that will only write back
to the disk when it needs to, preferably at shutdown only?

I know there are some options to reduce the amount of writes to a disk,
but how long can a write be avoided?
