Drive Specifications

2.9

Environmental specifications

2.9.1 Ambient temperature

Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual
drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions.

2.9.2 Temperature gradient

2.9.3 Humidity

2.9.3.1

Relative humidity

2.9.3.2

Wet bulb temperature

2.9.4 Altitude

2.9.5 Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive
mounting screws. Shock may be applied in the X, Y or Z axis.

2.9.5.1

Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum
operating shock of 70 Gs based on half-sine shock pulses of 2 ms during read operations. Shocks should not be
repeated more than two times per second.

2.9.5.2

Non-operating shock

1000 and 750GB models

The non-operating shock level that the drive can experience without incurring physical damage or degradation in
performance when subsequently put into operation is 300 Gs based on a non-repetitive half-sine shock pulse of 2
ms duration.
