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.
