2.11RELIABILITY

2.11.1Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

The product shall achieve an Annualized Failure Rate (AFR) of 0.63% (MTBF of 1.4 million hours) when operated at nominal power and typical case temperatures of 40°C. Operation at temperatures outside the specifications in Section 2.7 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 business critical storage system environments:

•8760 power-on-hours per year.

•Operations at nominal voltages.

•Temperatures outside the specifications in Section 2.7 may reduce the product reliability.

•A workload rate below the average annualized specified limits. Operation at excessive I/O duty cycle may degrade product reliability.

The enterprise application nearline environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR and MTBF.

Nonrecoverable read errors	1 per 1015 bits read, max
Annualized Failure Rate (AFR)	0.63% (nominal power, 40°C case temperature)

Load unload cycles	600,000 cycles

Rated Workload	Average rate of <550TB/year
	The MTBF specification for the drive assumes the I/O workload does not exceed the
	Average Annualized Workload Rate Limit of <550TB/year. Workloads exceeding the
	annualized rate may degrade the drive MTBF and impact product reliability. The Average
	Annualized Workload Rate Limit is in units of TB per year, or TB per 8760 power on
	hours. Workload Rate Limit = TB transferred * ( 8760 / recorded power on hours).

Warranty	To determine the warranty for a specific drive, use a web browser to access the following
	web page: http://www.seagate.com/support/warranty-and-returns/
	From this page, click on the "Verify Your Warranty" link. You will be asked to provide the
	drive serial number, model number (or part number) and country of purchase.The system
	will display the warranty information for your drive.

Preventive maintenance	None required.
