Environmental limits
Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part.
Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C).
2.6.1
Temperature
a. Operating
41°F to 140°F (5°C to 60°C) temperature range with a maximum temperature gradient of 36°F (20°C) per hour as reported by the
drive.
The maximum allowable drive reported temperature is 140°F (60°C).
Air flow may be required to achieve consistent nominal drive temperature values (see
). To confirm that the required
cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and perform random write/
read operations. After the temperatures stabilize, monitor the current drive temperature using the SMART temperature attribute
194 or Device Statistics log 04h page 5.
b. Non-operating
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that
the drive is packaged in the shipping container designed by Seagate for use with drive.
2.6.2
Humidity
The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).

Effective Altitude (sea level)
2.7
Shock and Vibration
Shock and vibration measurements specified in this document are made directly on the drive itself and applied in the X, Y, and Z axis at the drive
mounting point locations.
2.7.1
Shock
a. Operating
The drive will operate without error while subjected to intermittent shock pulses not exceeding 70 Gs (read) and 40 Gs (write) at
a duration of 2ms.
b. Non-operating
The drive will operate without non-recoverable errors after being subjected to shock pulses not exceeding 300g at a duration of
2ms.
2.7.2
Vibration
a. Linear Random Operating Vibration
The drive will operate without non-recoverable errors while being subjected to the random power spectral density noise
specified below.
Note
To maintain optimal performance drives should be run at nominal drive temperatures and humidity.
See
for rated MTBF device operating condition requirements.
Operating:
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Non-operating:
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Operating:
–304.8 m to 3048 m (–1000 ft. to 10,000+ ft.)
Non-operating:
–304.8 m to 12,192 m (–1000 ft. to 40,000+ ft.)
