[ardour-users] Ardour not using available memory?

[Jan Depner]

Oh, I forgot to mention.  DO NOT buy SCSI disks unless you're sure that
your controller won't give you the same kind of problems that the
Adaptec 29.. family has
(http://www.staudio.de/kb/english/conflicts/index.html#2940)
This has been reported with other controllers as well.  If you want to
read a very interesting article on performance differences between SCSI
and IDE for audio work read

It may surprise you.
