Abstract
A system and method for storing data including receiving a request to write data and in response to the request selecting a set of free physical locations in persistent storage. The system and method further include determining an aggregate failure rate of the set of free physical locations, making a first determination that the aggregate failure rate is less than a failure rate threshold for the persistent storage and based on the first determination calculating a parity value using at least a portion of the data, and writing the data and the parity value to the set of free physical locations.
