F Figures 6, 7 and 8 identify the drive +5V current profiles for each model ST3146807FC, ST3733307FC and ST336607FC, respectively. The current during the various times is as shown: T0 T1 T2 T3 Power is applied to the drive. Spindle begins to accelerate under current limiting after performing internal diagnostics. Spindle is up to speed and the Head-Arm restraint is unlocked. Figure 6. Typical ST3146807FC drive +5V current profile Cheetah 10K. 6 FC Product Manual, Rev. F 23 Figure 7.

F ST3146807FC Typical power dissipation under idle conditions is 10. 72 watts (37. 3 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 9). 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.
