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.
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 average minimum cycles for reliable start/stop function.
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.
