Question

The reliability of a hard-disk drive is typically described in terms of a quantity called mean time between failures (MTBF). Although this quantity is called a "time," the MTBF actually is measured in drive-hours per failure. True or False?

Answer 1

Answer:

True

Explanation:

MTFB is arithmetic mean time between drive failures.

Following is formula to calculate MTFB

$MTFB= \frac{summation of(Downtime start - uptime start)}{total number of failures}$
