2.5.1 MTTF
The reliability figure of merit most often used for electronic equipment is Mean
Time To Failure (MTTF). SanDisk estimates MTTF using a prediction
methodology based on reliability data for the individual components in
SanDisk products.
Component data comes from several sources: device life tests, failure analysis
of earlier equipment, device physics, and field returns.
SanDisk uses following methods to predict reliability:

configurations. The analysis was performed using a RAM Commander™ failure
rate prediction.

Electronic Components used in Telecommunication System.
Failure Rate: The total number of failures within an item population,
divided by the total number of life units expended by that population,
during a particular measurement interval under stated condition.
Mean Time To Failures (MTTF): A basic measure of reliability for
repairable items: The mean number of life units during which all parts of
the item perform within their specified limits, during a particular
measurement interval under stated conditions.
