For example, a 1U rack filled with twenty-four 500 GB Constellation drives that have entered PowerChoice technology C mode delivers 12 TB of storage, yet consumes only 43W or slightly more power than a single 40W light bulb! Delivering a combination of energy efficiency and user flexibility. The result? PowerChoice technology decreases drive power consumption by up to 54 percent in enterprise environments. ![]() In HDDs standards, there is one that's used as an automatic power-saving feature that is activated during very brief periods of command inactivity without impacting performance, it is called PowerTrim technology, but PowerChoice now called Power Control technology (a proprietary implementation of T10 Approved Standard No T10/09-054 and T13 Standard No T13/452-2008) complements PowerTrim technology by enabling even greater power reductions that cover idle periods greater than one second. There is a "feature" to put it in a way that can be de-enabled to help reduce noise (PowerControl) but first a little background on why Seagate uses proprietary technology that can be disabled and why it is not disabled by default.
