Abstract
Disk drives are the most commonly used secondary storage devices in computer
systems. The way operating systems access these devices leads to a wide range
of variability in access time. In this report we study the detailed temporal
characteristics of disk drives. We describe a comprehensive set of experiments
designed to build a model for the disk drive. Simulation is used to validate
the model. This disk model will help design a device driver which can achieve
a high degree of temporal determinacy.
