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 82°F (28°C).

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 temperature gradient of 36°F (20°C) per hour.

The maximum allowable drive case temperature is 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). Occa-
sional excursions in operating temperature between the rated MTBF temperature and the maximum drive 
operating case temperature may occur without impact to the rated MTBF temperature. 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 con-
firm 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.

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. 

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.
