[1] Measured with average reading DC ammeter. Instant12V current peaks will exceed these values.
Power supply at nominal voltage. N (number of drives tested) = 6, 35 Degrees C ambient.
[2] For +12 V, a -10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 10.5K 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 2.
[4] This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup primitive.
[5] See paragraph 6.4.1, "Conducted noise immunity." Specified voltage tolerance includes, noise, and transient response.
[6] Operating condition is defined as random 8 block reads.
[7] During idle, the drive heads are relocated every 30 seconds to a random location within the band from three-quarters to maximum track.
