Yes. Maybe someone who knows the inards of PS can tell whether PS
accesses multiple scratch disks on a multiprocessor system. Ideally PS
should be able to parallelize sub tasks for layer groups where
possible (maybe it is already doing it). Perhaps with a striped set
the need to access multiple drives (or partitions) is not that
urgent.

Ideally the scratch disk should at least be in a dedicated partition
to avoid performance degradation due to drive fragmentation. It should
have nothing except the scratch file. Once PS opens a file it works
entirely off of its temporary image until it is saved (or reverted).
