The annualized average failure rate (AFR) applies to the period prior
to the expiration of component design life, and is based on failures
chargeable to Maxtor.
Maxtor does not differentiate between various usage profiles (e.g.,
power-on hours, power saving modes, non-operating periods or
operating temperatures within the published specification.)
The quality acceptance rate indicates the percentage of Maxtor
products successfully installed by our customers, and/or the number
of defective parts per million (DPPM) encountered during the entire
installation process.
This indicates the minimum cycles for reliable start/stop function at a
60% confidence level.
Data errors (non-recoverable). Average data error rate allowed with all
error recovery features activated.
Component design life is defined as a.) the time period before
identified wear-out mechanisms impact the failure rate, or b.) the time
period up to the wear-out point when useful component life expires.
