A method for handling input/output (I/O) in a data storage system comprising a RAID subsystem storing data according to a RAID level utilizing a parity scheme, where RAID stripes have been configured across a plurality of data storage devices. The method may include monitoring write requests to the RAID subsystem, identifying write requests destined for the same RAID stripe, and bundling the identified write requests for substantially simultaneous execution at the corresponding RAID stripe. Monitoring write requests to the RAID subsystem may include delaying at least some of the write requests to the RAID subsystem so as to build-up a queue of write requests. In some embodiments, identifying write requests and bundling the identified write requests may include identifying and bundling a number of write requests as required to perform a full stripe write to the corresponding RAID stripe. |
