Abstract
The paper presents an analysis of buffered disk subsystems. First, the waiting time to start the service of an IO request is modelled. The model shows that the waiting time is negligible. This is a motivation to model a buffered disk subsystem. The average response time in such a subsystem can be reduced by 50%, and throughput can be doubled in comparison to a standard subsystem.
