Abstract
Software executing in a hard disk drive's host computer system increases the perceived efficiency and performance of the hard disk drive. The host computer system implements a “virtual disk” that models physical parameters associated with the actual hard disk drive, such as seek time and physical location of the read/write heads. These parameters are used to implement host based disk drive optimization techniques such as command reordering and read-on-arrival commands.
