Hi Ian,
On a typical day we might collect 2-4 Tb of movie data. Depending on
detector choice, movie length, how many images per hole, etc this may go
up or down several times. If your project may take 10 sessions, then you'd
be looking at some 50Tb of raw data. After movie-alignment that will
reduce 20-fold, but for particle polishing one needs to store extracted
movie-particles, which (depending on the coverage of the particles on the
micrographs) may become quite large again.
In general, the processing itself is not too expensive in disk space, and
many intermediate results could be deleted to save more space.
HTH,
Sjors
