Comment (by danielk):

 The ionice hack should really have no effect on recording. There are
 multiple buffers between the recording hardware and writing to disk. There
 is a device reading thread with a buffer + file writing thread with a
 buffer.

 BTW if you have dedicated recording drives it's better to use the deadline
 scheduler than cfq (ionice only works with the cfq scheduler).

 Use something like this in your rc.local:
 {{{
 echo deadline > /sys/block/sda/queue/scheduler
 echo 1 > /sys/block/sda/queue/iosched/fifo_batch
 }}}

 Can you attach a log where it the symptoms are "reduced" ?
