On the machine I mentioned earlier in this thread we use the Megaraid
for JBOD, but the card setup to use the disks that way was somewhat
confusing, requiring us to configure logical drives that in fact matched
the physical ones.  The card still wanted to write that information onto
the disks, reducing the total disk space available by some amount, but
also meaning that we were unable to migrate our system from a previous
non-RAID card cleanly.
