Reliability

The production disk drive shall achieve an annualized failure-rate of 0.44% (MTBF of 2,000,000 hours) over a 5 year service life when

used in Enterprise Storage field conditions as limited by the following:

• 8760 power-on hours per year.

• HDA temperature as reported by the drive <= 40°C

• Ambient wet bulb temp <= 26°C

• Typical workload

• The AFR (MTBF) is a population statistic not relevant to individual units

• ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the device)

The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature and

humidity. Occasional excursions in operating conditions between the rated MTBF conditions and the maximum drive operating

conditions may occur without significant impact to the rated MTBF. However continual or sustained operation beyond the rated

MTBF conditions will degrade the drive MTBF and reduce product reliability.

Workloads exceeding the annualized rate may degrade the drive MTBF and impact product

reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on

hours. Workload Rate = TB transferred * (8760 / recorded power on hours).
