Drive Specifications
2.11 Reliability - Mean Time Between Failure
The product will achieve a Mean Time Between Failure Rate (MTBF) of 1,000,000 hours when operated in an environment
of ambient air temperatures of 25°C. Operation at temperatures outside the specifications shown in
Section 2.8
may
decrease the product MTBF. MTBF is a population statistic that is not relevant to individual units.
• MTBF specifications are based on the following assumptions for NAS environments:
• 8760 power-on hours per year
• 10,000 average motor start/stop cycles per year
• Operations at nominal voltages
• Temperatures outside the specifications in
Section 2.8
may reduce the product reliability.
Operation at excessive I/O duty cycle may degrade product reliability. The NAS environment of power-on hours,
temperature, and I/O duty cycle affect the product MTBF. The MTBF will be degraded if used in an enterprise application.
2.12 Warranty
To determine the warranty for a specific drive, use a web browser to access the following web page:
http://www.seagate.com/support/warranty-and-replacements/
From this page, click on "Check to see if the drive is under Warranty". Users will be asked to provide the drive serial number,
model number (or part number) and country of purchase. The system will display the warranty information for the drive.
2.13 Agency certification
2.13.1 Safety certification
These products are certified to meet the requirements of UL60950-1, CSA60950-1 and EN60950 and so marked as to the
certify agency.
2.13.2 Electromagnetic compatibility
Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic
Compatibility Directive (2004/108/EC) as put into place 20 July 2007. Testing is performed to the levels specified by the
product standards for Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the
immunity levels are defined by EN 55024.
Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when
used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for
operation inside a properly designed enclosure, 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 their products.
