Modern processor technology advances much faster than magnetic recording technology. This mismatch makes disk system performance a dominant factor in overall system behavior. There is a need to construct simulation models of disk systems to determine and quantify the performance impact of alternative designs. This paper describes a system-assisted disk I/O simulation technique. This technique uses the real system to help simulate, relieving the burden to model the target system. It accepts

In addition, we describe a disk trace collection technique capable of collecting accurate trace data from the Windows 95 operating system. This simulation technique is evaluated and found to be an accurate predicator of disk service times.
