Abstract
A storage system, a disk controller, a disk drive and a method of operating thereof. The method includes: configuring a disk drive in a manner enabling executing one or more read requests concurrently with executing one or more write requests addressed to the same data track of the disk drive; responsive to a received write request addressed to a certain track of the disk drive, identifying with the help of the control layer one or more read requests concurrent to received write request and addressed to the same track; if the received write request and the identified one or more read requests match a predefined criterion, generating and issuing, with the help of the control layer, a command to the disk drive for executing a single task corresponding to the concurrent read and write requests combined in accordance with a certain mask.
