We have the main DB server on our portal running directly on some of
these Its a high volume site so
we really needed the speed. They are supposed to last 6 years but we
shall see. We have the 1 TB version, all mirrored giving us 500 GB. We
run solaris 10 on top with zfs, so we should see any data corruption
very quickly if it starts to happen. The cluster has been running for
about a year now
