Bastards:

"Failure rates are known to be highly correlated with drive
models, manufacturers and vintages [18]. Our results do
not contradict this fact. For example, Figure 2 changes
significantly when we normalize failure rates per each
drive model. Most age-related results are impacted by
drive vintages. However, in this paper, we do not show a
breakdown of drives per manufacturer, model, or vintage
due to the proprietary nature of these data."
