HDD by Model
Please take all columns into account when reading the table. Pay attention on the number of tested samples and power-on days. Simultaneous high values of both MTBF and errors are possible if only rare drives in the subset encounter errors.
Days — avg. days per sample, Err — avg. errors per sample, MTBF — avg. MTBF in years per sample.
