PRODUCT SPECIFICATIONS
3 – 4
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.
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
TBD (< 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.
Data Reliability
< 1 per 10
14
bits read Data errors (non-recoverable). Average data error rate allowed with all
error recovery features activated.
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 when useful component life expires.
