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.

J.E.B.
