Seagate 1200 SSD Product Manual, Rev. C 35
[1] Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these values. Power sup-
ply at nominal voltage. N (number of drives tested) = 6, 60 Degrees C ambient.
[2] For +12 V, a –10% tolerance is allowed during initial start but must return to ±5% before reaching ready state. 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] This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup
primitive.
[4] See paragraph 6.3.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and transient
response.
General DC power requirement notes.
1. Minimum current loading for each supply voltage is not less than 1.7% of the maximum operating current shown.
2. The +3.3V, +5V and +12V supplies should employ separate ground returns.
3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power
requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be
available to each device.
4. Parameters, other than start, are measured after a 10-minute warm up.
