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.
