Comment (by Craig Treleaven <ctreleaven@…>):

 I was not using Disk Speed Tools.  I'd installed and tried bonnie++ but
 itseems to be broken.  Tried again with bonnie (64 bit):

 {{{
 bonnie -d /Volumes/Theatre/Music -m Media-Mini
 File '/Volumes/Theatre/Music/Bonnie.14734', size: 104857600

 }}}

 Comparing that with the internal disk:
 {{{

               -Per Char- --Block--- -Rewrite-- -Per Char- --Block---

 1733  3.9
 }}}

 Looks OK to me.
