Reliability Characteristics
Uncorrectable Bit Error Rate (UBER)
The uncorrectable bit error rate is one error per 10
16
bits read.
Mean Time to Failure (MTTF)
Mean Time to Failure (MTTF)
23
is a reliability figure that indicates the expected time
to failure of non-repairable electronic equipment. Estimates of MTTF made 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
(ground, benign) environment.
The MTTF for all WD Blue 3D NAND SATA SSD form factors and storage capacities is
1,752,000 hours.
23
Based on internal testing using Telcordia stress part testing.
