5.0Reliability specifications

The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints

Seek error rate	Less than 1 error in 107 seeks
Read Error Rates1
Recovered Data	Less than 10 errors in 1012 bits transferred (OEM default settings)
Unrecovered Data	Less than 1 sector in 1014 bits transferred
Miscorrected Data	Less than 1 sector in 1021 bits transferred
Interface error rate	Less than 1 error in 1011 bits transferred with minimum receive eye
	Less than 1 error in 1014 bits transferred with typical receive eye
	(see Section 9.6.4, "Differential PECL input." on page 68)
MTBF	1,000,000 hours
Service life	5 years.
Warranty	To determine the warranty for a specific drive, use a web browser to
	access the following web page:
	www.seagate.com/support/service/
	From this page, click on the “Verify Your Warranty” link. You will be
	asked to provide the drive serial number, model number (or part num-
	ber) and country of purchase. The system will display the warranty infor-
	mation for your drive.
Preventive maintenance	None required.

1.Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.

5.1Error rates

The error rates stated in this manual assume the following:

•The drive is operated in accordance with this manual using DC power as defined in paragraph 6.2, "DC power requirements."

•Errors caused by host system failures are excluded from error rate computations.

•Assume random data.

•Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time.
