Add Primary NVMe Idle Timeout to Power Options in Windows 10

How to Add or Remove Primary NVMe Idle Timeout from Power Options in Windows 10

Modern PCs include NVMe devices to store your data instead of the classic HDD. NVMe stands for Non-Volatile Memory Express, which is often implemented as NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCI Express (PCIe) add-in cards, M.2 cards, and other forms. The technology allows parallel data reading and writing, thus giving incredible speeds.The Primary NVMe Idle Timeout option specifies the amount of time your NVMe device must be idle before transitioning to the primary non-operational power state, i.e. before switching to power saving mode.

The default values for this option are connected to power schemes available in Windows 10.

Power Scheme	On battery	Plugged in
Balanced	100 milliseconds	200 milliseconds
High Performance	200 milliseconds	200 milliseconds
Power Saver	100 milliseconds	100 milliseconds
Ultimate Performance	100 milliseconds	200 milliseconds

The Primary NVMe Idle Timeout setting is hidden and not visible by default, but you can easily make it available in Power Options of Windows 10. Here's how it can be done.
