Average Maximum Operating Power Consumption; Peak Power And Maximum Current Consumption - Western Digital WD Blue 3D NAND SATA SSD User Manual

Average Maximum Operating Power Consumption

Average maximum operating power consumption
3D NAND SATA SSD is continuously processing sequential read and write
commands (tested separately) for at least 1 minute, with a transfer size of 256
sectors per command (128KB). The sampling interval is 125 milliseconds. This
benchmark is designed to test the worst-case scenario, i.e., when continuous
power is required by the WD Blue 3D NAND SATA SSD during long read or write
command sequences.
Note: The power and current values in the following table are average
maximum with 20% margin.

Peak Power and Maximum Current Consumption

Peak power consumption
measured while the WD Blue 3D NAND SATA SSD is continuously processing
sequential read and write commands (tested separately) for at least one minute
with a transfer size of 256 sectors per command (128KB). The sampling interval is
10µs (microseconds). This benchmark is designed to test the worst-case scenario,
i.e., when continuous power is required by the WD Blue 3D NAND SATA SSD during
long read or write command sequences.
Maximum current refers to the maximum operating power that can be applied
continuously to the WD Blue 3D NAND SATA SSD drive without harming the drive.
The power and current values in the following table are average
