Abstract
A system and method for writing data a series of partial stripe writes to a redundant array of independent disks (RAID) with parity system. In one embodiment, the RAID with parity system is implemented as a log-structured storage system. In the RAID with parity system, each of the partial stripe writes can be issued before the active stripe is fully written. To buffer each partial stripe write, some data from each partial stripe write can be written to a scratch stripe before being written to the active stripe so that only writes of a predetermined size are issued to the active stripe. Other embodiments are also described herein.
