1.2.10 Reliability
1.2.10.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The production disk drive shall achieve an annualized failure-rate of 0.87% (MTBF of 1,000,000 hours) over a 5 year
service life w
hen used in Enterprise Storage field conditions as limited by the following:
 8760 power-on hours per year.
 HDA temperature as reported by the drive <= 30°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.
1.2.11 Agency and Safety Certifications
Each Hard Drive and Solid State Drive ("drives") has a product label that includes certifications that are applicable to
that specific drive. The following information provides an overview of requirements that may be applicable to the
drive.
1.2.11.1 Safety certification
The drives are recognized in accordance with UL/cUL 62368 -1 and EN 62368 -1.
1.2.11.2 Regulatory Models
The following regulatory model number represent all features and configurations within the series:
Regulatory Model Numbers: STL006
Nonrecoverable read errors
1 per 10
15
bits read, max
Load unload cycles 300,000 cycles
Maximum Rated Workload Maximum rate of <180TB/year
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).
