Abstract
A data storage device includes a plurality of hold-up capacitors configured to provide back-up power for a non-volatile memory, a controller, and a write cache. The controller is configured to detect one or more failed hold-up capacitors of the plurality of hold-up capacitors; and in response to detecting the one or more failed hold-up capacitors: perform one or more quiesce operations and determine a count of the one or more failed hold-up capacitors. Based on the count of the one or more failed hold-up capacitors, the controller is configured to reallocate the write buffers of the write cache for use in one or more subsequent write operations.
