Access Time (735 words) |
 | Access time is the metric that represents the composite of all the other specifications reflecting random performance positioning in the hard disk. |
| Since command overhead and settle time are both relatively small and relatively similar between drives, that leaves the sum of seek time and latency as the defining characteristic between drives. |
| Seek time and latency are a result of very different drive performance factors--seek time being primarily a matter of the actuator and latency the spindle motor--resulting in the possibility of some drives being better in one area and worse in another. |
