Performance Evaluation Metrics: Can buffer size override the higher rotational speed of hard disk in terms of overall performance

The aim of performance evaluation is to find out some performance metrics for systems under consideration or for prototypes to workout novel systematic and methodological basis for some portions of performance evaluation, discover methods to use speculative methods in conceiving and assessing performance models. In this paper measurement based performance evaluation techniques have been applied to two hard disks of same storage capacity but of different rotational speeds. Results have been studied, plotted and discussed. [Journal of American Science 2010;6(10):503-508]. (ISSN: 1545-1003).
