Seagate ST1000VM002 Environmental specifications Drive case temperature, Temperature gradient

2.9Environmental specifications

2.9.1 Drive case temperature

Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Drive case temperature should be measured at the location indicated in Figure 4.

2.9.2 Temperature gradient

2.9.3 Humidity

2.9.3.1Relative humidity

2.9.3.2Wet 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.

2.9.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 80 Gs based on half-sine shock pulses of 2ms during read operations. Shocks should not be repeated more than two times per second.

2.9.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 300 Gs (for 2TB model) and 350 Gs (for 1TB) based on a nonrepetitive half-sine shock pulse of 2ms duration.
