6. Reliability Characteristics

6.1 Error Rate

Non-recoverable error rate is 1 error per 10

6.2 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.
