G 7. 0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 7. 1 None. AC power requirements 7. 2 DC power requirements The voltage and current requirements for a single drive are shown below. The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply.

For +12 V, a ­10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 9, 936 RPM. 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. Figure 20. 300GB (at 6 Gbit) DC current and power vs. input/output operations per second 28 Savvio 10K. 3 SAS Product Manual, Rev.
