Systems, methods, and media for reducing power consumption of multi-plane non-volatile memory solid-state drives Cross-reference regarding related applications This application claims the benefit of U.S. Patent Application No. 18/243,551 filed on September 7, 2023, the entirety of which is incorporated herein by reference. Solid-state drives (SSDs) are widely used in grid-powered and battery-powered computing devices to store information. A multi-plane non-volatile memory (MPNVM) SSD is an SSD comprising MPNVM devices that constitute the SSD, wherein each MPNVM device has multiple planes that can be written to simultaneously on the device. A NAND SSD is a form of MPNVM SSD and includes NAND devices that are a form of MPNVM device. When reading information from an MPNVM SSD, power is consumed not only to operate the general circuitry of an MPNVM device (which may be part of an MPNVM SSD) but also to operate a specific plane of the MPNVM device being read. To improve efficiency and reduce battery drain (in battery-powered devices), it is desirable to reduce the power consumption of MPNVM SSDs. Therefore, new mechanisms to reduce the power consumption of MPNVM SSDs are desirable. According to some embodiments, mechanisms for reducing power consumption of MPNVM SSDs (which may include systems, methods, and media) are provided. In some embodiments, systems for reducing power consumption of multi-plane non-volatile memory (MPNVM) solid-state drives (SSDs) are provided, comprising: memory; and at least one hardware processor coupled to the memory, wherein the at least one hardware processor is collectively configured to: identify a first MPNVM device and a first plane of the first MPNVM device associated with a first command; determine that one or more other commands are available for the first MPNVM device and for a plane of the first MPNVM device different from the first plane; and in response to determining that one or more other commands are available for the first MPNVM device and for a plane of the first MPNVM device different from the first plane, transmit the first command and one or more other commands to the first MPNVM device for execution.
