2.12.1 Data loss under power interruption with write cache enabled

Drive preserves its data during all operations except in cases where power to the drive is interrupted during write operations. This
could result in either an uncorrected data error being reported, or the entire sector/track becoming unreadable. This can be
permanently recovered by rewriting to the same location on the drive. Additionally any data present in the DRAM buffer will not be
written to the disk media, additionally, the drive will not be able to return the original data.
In order to prevent this data loss, the host should issue a standby immediate or flush cache command before a controlled power off
operation to the drive.

Corrosive Environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing
sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential
application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive
component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are
especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic
components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient
relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should
be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free
alternatives.

Average annualized workload rating: <55 TB/year.
The specifications 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 and impact
reliability as experienced by the particular application. The average annualized workload rate limit is
in units of TB per calendar year.
