Seagate ST1000VX000 ユーザーズマニュアル

When properly installed in a representative host system, the drive operates without errors or degradation in 
performance when subjected to the radio frequency (RF) environments defined in 

The product will achieve an Annualized Failure Rate (AFR) of <1% when operated in an environment of ambient air 
temperatures of 25°C. Operation at temperatures outside the specifications shown in 

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 

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 an enterprise application.

model number (or part number) and country of purchase. The system will display the warranty information for your 
drive.
