Patent ID: 7555599

Claim:
A method of mirrored RAID array write management, comprising: receiving a write request to a minored RAID array; determining whether the write request is for writing to a read optimized region, the read optimized region being a designated LBA region in which physical movement of read/write head is limited to the designated LBA region; queuing the write request to a write queue if the write request is not writing to the read optimized region; determining whether the write queue reached a selected threshold; if the write queue has reached the selected threshold, ordering a plurality of write requests in the write queue sequentially to map to logical block addresses of a hard disk drive; and transferring the plurality of write requests to the hard disk drive one at a time in a burst of transactions, wherein if it is determined that the write request is for writing to the read optimized region, the write request is sent to HDD and not queued to the write queue.
