[2] For +12 V, a –10% tolerance is allowed during initial spindle start but must return to ±5% before reaching
9,936 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 16.
[4] See +12V current profile in Figure 17.
[5] This condition occurs after OOB and Speed Negotiation completes but before the drive has received the
Notify Spinup primitive.
[6] See paragraph 6.3.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and
transient response.
[7] Operating condition is defined as random 8 block reads.
