1. A device for measuring a power consumption of a solid-state drive, comprising:
an adaptor comprising:
a first end coupled to the solid-state drive that is communicatively coupled to a server backplane within a server chassis;
a second end coupled to the server backplane;
a power sensing circuit configured to perform a power measurement to generate a value corresponding to the power consumption of the solid-state drive;
at least one analog-to-digital converter (ADC) configured to operate using a first bit-width and a first dynamic range, and sample the value to generate a digital value; and
a wireless transceiver configured to operate using at least one wireless protocol and transmit the digital value to a recording unit.
