Reliability
2.11.1 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.

Agency and Safety Certifications
Each Hard Drive and Solid State Drive ("drives") has a product label that includes certifications that are applicable to that specific drive. The follow-
ing information provides an overview of requirements that may be applicable to the drive.
2.12.1 Safety certification
These products are certified to meet the requirements of UL/cUL 60950-1, EN 60950-1, and may also include, IEC 62368, UL 62368 and EN 62368.
The following regulatory model number represent all features and configurations within the series:
Regulatory Model Numbers: SDC001/SDC003
2.12.2 European Union (EU) CE Marking Requirements
Drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic Compatibility
Directive (2014/30/EU) put into force on 20 April 2016. Testing is performed to the levels specified by the product standards for
Information Technology Equipment (ITE). Emission levels are defined by EN 55032:2012, Class B and the immunity levels are defined
by EN 55024:2010.
The drives also meet the requirements of The Low Voltage Directive (LVD) 2014/35/EU.
Seagate drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with all relevant
regulatory requirements and standards for the drives, Seagate cannot guarantee that all system-level products into which the drives
are installed comply with all regulatory requirements and standards applicable to the system-level products. The drive is designed
for operation inside a properly designed system (e.g., enclosure designed for the drive), with properly shielded I/O cable (if
necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC
compliance and provide CE marking for the system-level products.
For compliance with the RoHS "Recast" Directive 2011/65/EU (RoHS 2),
See Section 2.13.1.1 on page 20.
2.12.3 Australian RCM Compliance Mark
If these models have the RCM marking, they comply with the Australia/New Zealand Standard AS/NZ CISPR32 and meet the
Electromagnetic Compatibility (EMC) Framework requirements of the Australian Communication and Media Authority (ACMA).

Rated workload
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.
