the best documented case i'm personally familiar with was an FOH
engineer using ardour. if he kept the (external) drive on the same
table as the mixing console, ardour would fail to "keep up" with disk
i/o. if he put a drum shield box in front of the table, no problems.
if he put the disk into the cabinet below the console, no problems. if
the band played quietly, no problems.

and then there is the sun testing work that arnold referred to.
