100GB models in 6Gb operation

Typical power dissipation under idle conditions in 6Gb operation is 4.04 watts 13.79 BTUs per hour).

To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 6). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123.

7.5Environmental 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 82°F (28°C).

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

7.5.1Temperature a. Operating

The drive meets the operating specifications over a 32°F to 140°F (0°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 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 7.5). To con- firm that the required cooling is provided, 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 7 and 8 for temperature checkpoint.
