Systems and methods are disclosed for data storage performance scaling based on external energy. In certain embodiments, a system may comprise a data storage device having an interface to communicate with an external device, a nonvolatile memory, and a circuit. The circuit may be configured to receive an indication via the interface of power resources available to the data storage device from the external device in case of a power loss event, adjust a performance metric of the data storage device to apply when accessing the nonvolatile memory during normal power availability based on the indication, and perform operations during normal power availability based on the performance metric.
