Simulation system for auxiliary power supply in storage devices

A simulation system comprising:

• a storage device including an auxiliary power supply configured to generate an auxiliary power, the storage device being configured to, based on detecting a sudden power-off (SPO) event, perform a power loss protection (PLP) procedure associated with backing up operation data based on the auxiliary power, and configured to store PLP data associated with the PLP procedure;
• and
• a storage simulator configured to, based on detecting the SPO event, perform a PLP simulation corresponding to the PLP procedure by using the PLP data, configured to generate a power consumption value by measuring an amount of power consumed while the PLP simulation is performed, and configured to determine a capacity of the auxiliary power supply based on the power consumption value,
• wherein the PLP procedure includes a dump preparation operation performed before the operation data are backed up, and
• wherein the PLP simulation includes a simulation dump preparation operation associated with the dump preparation operation that causes a maximum of power consumption in the auxiliary power supply.
