Reliability Specifications
Annual Return Rate
< 1.0% Annual Return Rate (ARR) indicates the average against products shipped.
ARR includes all reasons for returns (failures, handling damage, NDF), but
does not include inventory credit returns.
Quality Acceptance Rate
< 1,000 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 This indicates the average minimum cycles for reliable start/stop function.
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.
