SEAGATE VIDEO 2.5 HDD PRODUCT MANUAL, REV. A 11
DRIVE SPECIFICATIONS
2.10 ELECTROMAGNETIC IMMUNITY
When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected
to the radio frequency (RF) environment as defined in Table 7.
2.11 RELIABILITY
2.11.1 Annualized Failure Rate (AFR)
The product will achieve an Annualized Failure Rate (AFR) of 0.55% when operated in an environment of ambient air
temperatures of 25°C. Operation at temperatures outside the specifications in Section 2.8, Environmental Specifications may
increase the product AFR. AFR is a population statistics that is not relevant to individual units.
AFR specifications are based on the following assumptions for consumer electronics 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, Environmental Specifications may reduce the product reliability.
Normal I/O duty cycle for consumer electronics environments. Operation at excessive I/O duty cycle may degrade
product reliability.
The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR. The AFR
will be degraded if used in a enterprise application
