Reliability Specifications
AFR
< 1.7% 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. Determination of the AFR takes into account:
a.) in-warranty field failure returns less quality acceptance-related
failures and b.) an AFR equaling an exponentially weighted moving
and average monthly failure rate multiplied by 12.
MTBF
> 500,000 hours 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.)
Quality Acceptance Rate
99.85% (< 1,500 DPPM) 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.
Start/Stop Cycles
50,000 (minimum) This indicates the minimum cycles for reliable start/stop function at a
≥ 60% confidence level.

Component Design Life
5 years (minimum) 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 at which useful component life
expires.
