Seagate ST3146855LC Economies of Capacity and Speed: Choosing the most cost-ef - Page 7

APPENDIX C Short-Stroking (or Destroking) 10K-RPM Drives to Improve Access Time: As shown in Figure A4, destroking stores data on the shaded region on the outer diameter of the disc. The lighter area is available data storage that remains unused to keep seek times to a minimum. Such underutilized media results in a very high cost-perusable-GB and cost-per-IOPS solution for the end user. 15K-RPM disc drives lower access time without forcing users to sacrifice the capacity on the disc. Thus fewer 15K-RPM disc drives of a given capacity are needed to meet the performance requirements of the system. Figure A3.
