Benchmarking Linux filesystems on software RAID 1 (Lone Wolves)

I've gotta disagree with you slightly here, with regards to RAID without UPS being pointless.

While it's true that power glitches are significantly more common than hardware failures,
they're also significantly easier to recover from.  Minor data loss due to a power outage is a
lot better than complete data loss due to the failure of a non-RAID disk.
