The time to failure is highly variable with the longest operating run being ~13 hours fsck never reports any problems and shutting down before a freeze happens produces a clean restart with no orphaned inodes in the startup sequence. one recovery check of the file system (esc f2 during boot) showed 1 damaged file but I can't get that to replicate. smartctl output to follow:
