they are the same kind of filesystem, specifically journaling
filesystems. they guarantee that the filesystem (as a whole) is always
consistent (at the cost of "sacrifying" some files/dirs).

They are not constantly being written: there are buffers, and if a
part file is empied, the download will restart from 0, and for each
download there is just one part file. On the contrary, on ~/.aMule
there are files shared by all the downloads (so more changes per file)
so an update to a downloading file (for example for known) will
trigger an update, multiplied for all the downloading files it
increase the chance of a file corruption.

In any case, if you experience several power loss an UPS is in order,
and to solve the amule problem, a simple backup solution is more than
enough.
