Environmental Specifications | Seagate ST240HM000, ST120HM001

2.8ENVIRONMENTAL SPECIFICATIONS

2.8.1Temperature

Temperature is defined as the drive's internal temperature as reported by SMART attribute 194 for operation or the drive case temperature for non-operating.

Above 1000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3048 meters).

Operating:	0° to 70°C (32° to 158°F)

Nonoperating:	–40° to 75°C (–40° to 167°F)

2.8.2Temperature gradient

Operating:	20°C per hour (30°F per hour max), without condensation

Nonoperating:	20°C per hour (30°F per hour max)

2.8.3Humidity

2.8.3.1Relative humidity

Operating:	5% to 95% noncondensing (20% per hour max)

Nonoperating:	5% to 95% noncondensing (20% per hour max)

2.8.3.2Wet bulb temperature

Operating:	29°C (84°F max)

Nonoperating:	29°C (84°F max)

2.8.4 Altitude

** Operating:	–61 m to 3048 m (–200 ft. to 10,000+ ft.)

** Nonoperating:	–61 m to 12,192 m (–200 ft. to 40,000+ ft.)

** Applies to atmospheric pressure only.

2.8.5Shock

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.

2.8.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 1500 Gs based on half-sine shock pulses of 0.5ms. This specification does not cover connection issues that may result from testing at this level.

2.8.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 1500 Gs based on a half-sine shock pulse of 0.5ms duration.

2.8.6Vibration

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