Yes, but does Logic let you spread your audio files out among several
drives? That's a serious question. I don't know the answer.

I doubt it would cause any problem because your hard drive has a pretty
large buffer and the data is coming in pretty slow as far as the hard drive
is concerned. I don't think it would be a big deal. On top of that, I
suspect Logic is buffering that audio in RAM too. If the disk gets stuck
doing something for a second or two, Logic will just use up more RAM. At
least that's what I think would happen.

And yet on top of that, UNIX also has write behind buffering of data, so
that even if Logic isn't buffering, the OS certainly could be. It is
possible that Logic forces the OS to commit the data right away, but I don't
know enough about UNIX or OS X to talk intelligently about that. I do have a
high confidence level that the Logic guys anticipate that kind of thing and
that it shouldn't be an issue.
