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). Maximum wet bulb
temperature is 84.2°F (29°C).
To maintain optimal performance drives should be run at nominal case temperatures.

Temperature
a. Operating
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°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 tempera-
ture. 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 with-
out 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 6.5). To confirm that the
required cooling is provided, place the drive in its final mechanical configuration, and perform random write/read opera-
tions. After the temperatures stabilize, measure the case temperature of the drive. See Figure 14 and 15 for 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 the drive is packaged in the shipping container designed by Seagate for use with drive.
