![]() While the drive is idle, the drive can be at a near zero or zero idle power state, and NVMe architecture takes advantage of PCIe low power states to help achieve this. Non-operational power states are mainly used in consumer/client SSDs to improve battery life. It can also useful for improving data center TCO by reducing the max active power of the SSD, which reduces SSD performance, but can be tuned by workload to achieve an optimal TCO. This may be useful if a host knows it wants to write a considerable amount of data at once by giving a drive max power and performance. U.2, M.2, EDSFF) but a drive can use NVMe specification features to change an active power state. Max power is usually defined by a given form factor (e.g. In the data center, this can be used to throttle an SSD to a specific TDP (thermal design power) to manage platform thermals and total power draw. NVM Express (NVMe) architecture contains various features to manage the power of SSDs. NVMe™ Technology Power Management Features ![]()
