That's the kind of behaviour the last time I tried using ext4 for recordings.
After spending a day moving terabytes around to reinstate xfs as the
big filesystem, those issues went away again.

The Atom machines I have here can recording HD at the same time as playing
back the same or a different HD (Ion2 -- VDPAU for playback), and are glitch free.
They use a single drive, with ext4 for the main system and xfs for the recordings.
