Abstract
In general, embodiments of the technology relate to a method for storing data. More specifically, the method may include selecting a first RAID grid location in a RAID grid, where the first RAID grid location is flagged, selecting a second RAID grid location in the RAID grid, making a first determination that the second RAID grid location is not flagged, in response to the first determination, loading first data associated with the second RAID grid location into a cache, calculating a parity value for a corresponding set of RAID grid locations in a data grid using the first data in the cache, where the first RAID grid location and the second RAID grid location are in the set of RAID grid locations, and storing at least a copy of the first data and the parity value in a storage array comprising persistent storage.
