OK, so I don't change latency while actually
recording. Changing
latency requires restarting Jack and the audio apps. Probably I should
have said I test Ardour recording 48 channels to 3 drives with
different latency settings in Jack.
I use 3 Firewire drives and tell Ardour that they are attached. Ardour
decides what audio data goes on each drive, but roughly speaking it
spreads out the audio data across all three. When I first did this a
few years ago I ran into trouble trying to do this on a single
internal IDE drive, even if it wasn't the main system drive. It might
work better today with newer drivers and SATA drives. Don't know.
Hope this clears things up.

Yup. I very much wonder, if you would have less struggle sending all of
the streams to one RAID-10 set (that's four drives minimum) of either
internal SATA or eSATA. RAID-5 (three drives minimum) wouldn't help
because it accelerates read, but not write; but RAID-10 effectively
doubles both read and write speeds.
