True, but I still have doubts that the HDDs are the bottlenecks. They
aren't that slow and they've got several heads.

Other factors seem to be more important.

When I e.g. move a window, I get audible gaps without getting xruns,
while the audio session is that small, that everything is, resp. should
be in the RAM.

IOW I'm experiencing and I experienced all kinds of inexplicable issues
and IMO it's more likely that something is really fishy, than something
like using 1 instead of 2 drives does cause an issue.

It can't harm to use several drives, but I experienced using 1 drive
only doesn't cause (additional) issues. I own several drives myself and
usually I use 2 drives. Everybody with several drives could make tests
and use one drive only for a test. It shouldn't make a difference.
