4.10 RELIABILITY
Component Life: 5 years
Preventive Maintenance: Not required
Start/Stop: 40,000 cycles (minimum, @ 25 ° C [77°F])
Drive reliability is closely related to the temperatures to which the disk drive is
exposed. The operational design termperature ambient is 30°C (86°F). Temperature
ambient above 50°C (122°F) or below 5°C (41°F) may decrease drive reliability.
