By 'many small files' the developers are talking about something like a 
maildir based mail system, with 1000's of 4-10k files.  Any audio work is
going to have 'large' files (from a filesystem perspective).

I'll concur with the others who've suggested that you should focus on the
potential hardware bottlenecks before getting bogged down with the small
gains you may get tweaking filesystems.  (are you SURE your external hard
drive is using full speed USB (or firewire), or is there a chance it's
running at USB 1.1 speeds ?).

I haven't used XFS for Audio work (but have had success with ext3), the
truth is for raw write-speed performance the simpler the filesystem the
better the results .. simple things like using large blocks (4k) and
consider turning OFF journalling  and use system level partitioning (not
LVM) may give you a far greater performance boost than trying complex
fs types like Reiser.
