single-disk systems in production environments. Is RAID0 more prone to
crashes than a single disk? Obviously, the expected MTBF for a set of
two disks is shorter than just one of them, but is it really *that* much
shorter? In other words, if I feel quite at ease with a single disk,
should I really worry a lot about a 2-disk RAID0 system?
