2.12Reliability

2.12.1Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

The product shall achieve an Annualized Failure Rate (AFR) of 0.34% (MTBF of 0.7 million hours) when oper- ated in an environment of ambient air temperatures of 25°C. Operation at temperatures outside the specifica- tions in Section 2.9 may increase the product AFR (decrease MTBF). AFR and MTBF are population statistics that are not relevant to individual units.

AFR and MTBF specifications are based on the following assumptions for desktop personal computer environ- ments:

•2400 power-on-hours per year.

•10,000 average motor start/stop cycles per year.

•Operations at nominal voltages.

•Temperatures outside the specifications in Section 2.9 may reduce the product reliability.

•Normal I/O duty cycle for desktop personal computers. Operation at excessive I/O duty cycle may degrade product reliability.

The desktop personal computer environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR and MTBF. The AFR and MTBF will be degraded if used in a enterprise application.

Nonrecoverable read errors

1 per 1014 bits read, max

Annualized Failure Rate (AFR)

0.34% (nominal power, 25°C ambient temperature)

 

 

Contact start-stop cycles

50,000 cycles

 

(at nominal voltage and temperature, with 60 cycles per hour and a 50% duty cycle)

Warranty

5 years on distribution units.

2.13Agency certification

2.13.1Safety certification

The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950.

2.13.2Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec- tromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product standards for Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024.

Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products.
