Abstract
A method to access a data in a RAID array comprising a plurality of data storage media, wherein information is written to said plurality of data storage media using a RAID configuration, wherein the method receives from a requester a command comprising a data access priority indicator. If a RAID rebuild is in progress, the method determines if the data access priority indicator is set. If the data access priority indicator is set, the method executes a command selected from the group consisting of writing information to the target logical block array range, and returning to the requestor information read from the target logical block array range.
