Power-Up In Standby (PUIS)

Definition - What does Power-Up In Standby (PUIS) mean?

Power Up in Standby (PUIS) is a specific hard disk drive (HDD) feature that allows the drive to spin up only when necessitated by a command, rather than when turning on the computer. This helps save energy or allows staggered spin-up times for multiple disk drives.

Techopedia explains Power-Up In Standby (PUIS)

The implementation of PUiS requires input from the basic input/output system (BIOS). This system, which is a fundamental part of the PC and other types of hardware, helps users identify and control various commands that enable or disable features like PUiS. Experts have noted that PUiS has traditionally been most commonly used in systems that include multiple disk drives.

The principle behind PUiS is that device owners and users can save a lot of energy if the disk is not spinning when not required. This is an essential type of energy saving control for smaller devices or other energy-efficient devices. The emergence of other technologies, like solid state drives, are an alternative to the issue of power required to spin disk drives for input and output.
