3.0 QUALITY AND RELIABILITY

3.1 TRAY LOADER MECHANISM LIFE

The drive is capable of at least 30,000 tray loading/unloading operations

3.2 MTBF

The MTBF is 70,000 power on hours(POH) when operated at 25°C temperature, nominal voltage, and other
environmental limits, based on the following assumptions:
- the operating duty cycle is 10% of power on time. During this time, the drive is either reading or seeking (random
multiple block read).
