Abstract:
An embodiment of a data misalignment correction method for a mass storage controller system that couples drives having large internal block sizes to a computer operating system having input/output data block requests, including automatically determining an amount of misalignment between a request of the input/output data block to the storage controller and the controller's current data alignment configuration and using the amount of misalignment to realign the mass storage controller system configuration to match the operating system's input/output requests for optimizing input/output performance with the attached drives.
