MTTF (Mean-Time-To-Failure)
bits read.
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 in
accordance with the Telcordia Special Report SR-332. The prediction is based on a
Parts Stress Analysis.
Quality levels were defined as industrial grade (I) for all of the components. The
detailed prediction for the system was performed at a temperature of 25°C in a GB
environment.
The following table summarizes the estimated MTTF results for each capacity.
