Annualized Return Rate

< 1%

Annualized 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.

Load/Unload Cycles

> 600K

This indicates the average minimum cycles for reliable unload and load of head ramp (where heads are loaded and parked onto a ramp off the disk when not in use).

Data Reliability

< 1 per 1015 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.
