How about the far more regular crash case ? We may be pretty reliable but
we are hardly indestructible especially on random boxes with funky BIOSes
or low grade hardware builds.

For the generic sane low end server/high end desktop build with at least
two drive software RAID the hardware failure for data loss case is
pretty rare. Crashes yes, having to reboot to recover from a RAID failure
sure but data loss far less so
