2.10 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
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
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.
2.10.1 Storage
Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged
within the defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year
packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and
non-corrosive environment). During any storage period the drive non-operational temperature, humidity, wet bulb,
atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.
2.11 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 "Is my Drive 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.
2.12 Agency certification
2.12.1 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.
2.12.2 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 (Until 19th April, 2016) and 2014/30/EU (From 20th April, 2016). 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.
