SEAGATE 1200 SSD PRODUCT MANUAL, REV. A 22
6.0 PHYSICAL/ELECTRICAL SPECIFICATIONS
This section provides information relating to the physical and electrical characteristics of the drive.
6.1 POWER SPECIFICATIONS
The 2.5” drive receives DC power (+5V and +12V) through the standard SAS interface.
The 1.8" drive receives DC power (+3.3V and +5V) through the standard micro-SAS interface.
6.1.1 Power consumption
Power requirements for the drives are listed in the tables in Section 6.3. Typical power measurements are based on an
average of drives tested, under nominal conditions, using the listed input voltage at 60°C ambient temperature.
Measurements are made at 6Gb interface speeds. For 12Gb interface speed add 1W of total power to the values shown.
• Startup power
Startup power is measured from the time of power-on to the time that the drive reaches operating condition and can pro-
cess media access commands.
• Peak operating mode
During peak operating mode, the drive is tested in various read and write access patterns to simulate the worst-case
power consumption.
• Idle mode power
Idle mode power is measured with the drive powered up and ready for media access commands, with no media access
commands having been received from the host.
6.2 AC POWER REQUIREMENTS
None.
