Drive Specifications

2.12 Reliability

2.12.1 Annualized Failure Rate (AFR)

The production disk drive shall achieve an annualized failure-rate of <1.0% over a 5 year service life when used in Desktop

Storage field conditions as limited by the following:

• 2400 power-on-hours per year.

• Typical workload

2.12.2 Storage

Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged

within the defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year

packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and

non-corrosive environment). During any storage period the drive non-operational temperature, humidity, wet bulb,

atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

2.13 Agency certification

2.13.1 Safety certification

These products are certified to meet the requirements of UL60950-1, CSA60950-1 and EN60950 and so marked as to the

certify agency.

2.13.2 Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic

Compatibility Directive (2004/108/EC) as put into place 20 July 2007. 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.

Nonrecoverable read errors

1 per 1014 bits read, max

Rated Workload

Average annualized workload rating: <55 TB/year.

The AFR specification for the product assumes the I/O workload does not exceed the average

annualized workload rate limit of 55 TB/year. Workloads exceeding the annualized rate may

degrade the product AFR and impact reliability as experienced by the particular application.

The average annualized workload rate limit is in units of TB per calendar year.
