Measured with average reading DC ammeter. Instantaneous +12V 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 15K 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 sele ction
by the host initiator.
[3]
See +12V current profile in Figure 1.
[4]
This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup primitive.
[5]
See paragraph 6.3.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and transient response.
[6]
Operating condition is defined as random 8 block reads.
[7]
During idle, the drive heads are relocated every 60 seconds to a random location within the band from three-quarters to maxi mum
track.
