“Fault Tolerance systems lie.

Disk failures: Failure rates < 1% per year.
Study conducted proves that irrespective of age, disk failed... (couldn't catch that)

also, Temperature is not a major criterion for disk failures.

SMART disks…self monitoring. (!)

Even then, 56% of disks failing had no predictable behavior.

Well, more bad news: 70% of drives survive for 8 months. (So after 8 months, no predictability). So, SMART is not a great solution.”
