摘要： An interface controller of a storage device configured to manage a write cache of the storage device responsive to changes in a voltage supply provided to the storage device. In one implementation, the interface controller reduces the size of the write cache responsive to the voltage supply dropping at or below a first threshold. The interface controller further disables write permissions to the write cache responsive the voltage supply dropping at or below a second threshold, wherein the second threshold is lower in magnitude that the first threshold. The interface controller periodically receives the voltage supply responsive to transmitting sequential requests to a servo firmware of the storage device.
