ABSTRACT:
Minimal random disk write latency is achieved by limiting the number of logical address blocks that can be serviced by a disk to less that the actual number of physically addressable blocks of the system and having a disk controller dynamically map logical data blocks to physical disk blocks in such a fashion that each logical write can take place to any free location, where the free location can be chosen in any track of the current cylinder.
