*
One GB equals one billion 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
.
†
Seagate does not recommend operating at sustained case temperatures above 60°C.
Operating at higher temperatures will reduce useful life of the product.

Formatted capacity
*One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
2.2.1
LBA mode
When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to
n–1,
where
n
is
the number of
guaranteed sectors as defined above
.
See Section 4.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit addressing support
of drives with capacities over 137GB.
Vibration, operating
5–22 Hz: 0.25 Gs, Limited displacement
22–350 Hz: 0.50 Gs
350–500 Hz: 0.25 Gs

Annualized Failure Rate (AFR)
<1% based on 8760 POH
Maximum Rated Workload
Maximum rate of 180TB/year.
Workloads exceeding the annualized rate may degrade the drive MTBF and impact product reli-
ability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours.
Workload Rate = TB transferred * (8760 / recorded power on hours).
