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). Maximum wet bulb temperature is 84°F (29°C).
Note.

To maintain optimal performance drives should be run at nominal case temperatures.

a. Operating

The drive meets the operating specifications over a 41°F to 131°F (5°C to 55°C) drive case temperature range with a maximum tem -

perature gradient of 36°F (20°C) per hour.
The maximum allowable drive case temperature is 140°F (60°C).
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal case temperature. The rated 

MTBF is based upon a sustained case temperature of 122°F (50°C). Occasional excursions in operating temperature between the 

rated MTBF temperature and the maximum drive operating case temperature may occur without impact to the rated MTBF tempera -

ture. However continual or sustained operation at case temperatures beyond the rated MTBF temperature will degrade the drive MTBF 

and reduce product reliability.
Air flow may be required to achieve consistent nominal case temperature values (see Section 9.2). 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, measure the case temperature of the drive. See Figure 10 for HDA temperature checkpoint.

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 t he 

drive is packaged in the shipping container designed by Seagate for use with drive.

The values below assume that no condensation on the drive occurs.
a. Operating

5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.

b. Non-operating

5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.

a. Operating

–1000 to +10,000 ft (–304.8 to +3048 m)

b. Non-operating

–1000 to +40,000 ft (–304.8 to +12,192 m)
