Non-recoverable read errors	1 per 1014 bits read		1 per 1014 bits read	1 per 1014 bits read
Rated workload	Average rate of <55TB/year. The MTBF specification for the drive assumes the I/O workload does not
	exceed the average annualized workload rate limit of 55TB/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).

specification

*All specifications above are based on native configurations.

**One GB equals one billion bytes and 1TB equals one trillion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.

***During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.
