WebFeb 1, 2024 · The 16TB WDC drive cohort (model: WUH721816ALE6L0) has an average age of 5.06 months and an AFR of 0.14%. While the 16TB Toshiba drive cohort (model: MG08ACA16TE) has an average age of 3.57 months and an AFR of 0.91%. In both cases, the number of drive days is on the lower side, but these two drive models are off to a good start. Annualized failure rate (AFR) gives the estimated probability that a device or component will fail during a full year of use. It is a relation between the mean time between failure (MTBF) and the hours that a number of devices are run per year. AFR is estimated from a sample of like components—AFR and MTBF … See more For example, AFR is used to characterize the reliability of hard disk drives. The relationship between AFR and MTBF (in hours) is: $${\displaystyle AFR=1-exp(-8766/MTBF)}$$ See more • Failure rate • Frequency of exceedance See more maxlite light bulbs review
