[1]Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these val- ues. Power supply at nominal voltage. Number of drives tested = 6, 22 Degrees C ambient.

[2]For +12 V, a –10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 10,000 RPM. The ±5% must be maintained after the drive signifies that its power-up sequence has been completed and that the drive is able to accept selection by the host initiator.

[3]See +12V current profile in Figure 3.

[4]This condition occurs when the Motor Start option is enabled and the drive has not yet received a Start Motor command.

[5]See paragraph 6.2.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and transient response.

[6]Operating condition is defined as random 8 block reads at (ST3146807 at 234, ST373307 at 239 and ST336607 at 239) I/Os per second. Current and power specified at nominal voltages. Decreasing +5 volt supply by 5% increases 5 volt current by 3.6%. Decreasing +12 volt supply by 5% increases 12 volt cur- rent by 3%.

[7]During idle, the drive heads are relocated every 60 seconds to a random location within the band from track zero to one-fourth of maximum track.

[8]Values shown are for operation at 2 Gb; for operation at 1 Gb, reduce the +5V by 0.10 amps. The +12V current values are not affected by loop speed.

General DC power requirement notes.

1.Minimum current loading for each supply voltage is not less than 0.8% of the maximum operating current shown.

2.The +5V and +12V supplies should employ separate ground returns.
