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

Component Design Life
5 years (minimum)
Component design life is defined as:
a.) the time period before identified
or
b.) the time period up to the
