Sorry Dan, but he should at least try it, you never know.  Documentation on
my hard disk/controller suggested 4:1 was the best I could expect.  After
trying successively closer interleaves, disk performance went to s--t at
1:1 but was super at 2:1.  Peter, try successively closer interleave formats
followed with a test of disk performance such as included with Norton Utils.
When you have gone one too far, it will be immediately apparent, then go
back up one.  It may take a lot of time, but it sure is worth it.
