Disclosed are techniques for managing parity information for data stored on a storage device. A method can be implemented at a computing device communicably coupled to the storage device, and include (1) receiving a request to write data into a data band of the storage device, (2) writing the data into stripes of the data band, comprising, for each stripe of the data band: (i) calculating first parity information for the data written into the stripe, (ii) writing the first parity information into a volatile memory, and (iii) in response to determining that a threshold number of stripes have been written: converting the first parity information into smaller second parity information, and (3) in response to determining that the data band is read-verified: (i) converting the second parity information into smaller third parity information, and (ii) storing the smaller third parity information into a parity band of the storage device.
