DB35.3 Series Serial ATA Product Manual, Rev. D

Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. 
Actual drive case temperature should not exceed 75°C (167°F) within the operating ambient conditions. Rec-
ommended measurement locations are shown in Figure 5 on page 27.

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet 
(3,048 meters). 

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.

These drives comply with the performance levels specified in this document when subjected to a maximum 
operating shock of 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more 
than two times per second.
