The table shows the default idle timeouts and latency tolerances used by StorNVMe. This implies varying latency tolerances and timeouts will be used. If the system is in active use, StorNVMe will prefer responsiveness. This is the amount of time from when the device completed its last IO operation. That is, how quickly can the device respond if needed? The F-State is chosen based on 3 factors: StorNVMe may choose to transition the device to an F-State after a certain amount of idle time has elapsed. For Modern Standby support, StorNVMe does not support devices with APST enabled. The NVMe specification defines an Autonomous Power State Transition (APST) feature. With StorNVMe, transitions to these states is largely determined by the overall system power state. Likewise, the driver maps non-operational power states (the device does not handle IO in these states) to logical idle power states (a.k.a. StorNVMe maps operational power states (the device can handle IO in these states) to logical performance states (a.k.a. ![]() Relative performance values (relative to other power states).Each power state has the following parameters: The NVMe spec allows NVMe devices to report up to 32 power states. This section details how Microsoft’s in-box NVMe driver (StorNVMe) manages power and what configuration options are available. ![]()
