ABSTRACT:
Method for measuring performance of a storage device including rotatable media, for storing data to and/or retrieving data from said media via one or more data buffers. The measurement method includes the steps of: specifying one or more access patterns for transferring data to/from the media; and for each access pattern, specifying one or more different required data transfer rates, measuring the actual data transfer time of the storage device for transferring the data according to that access pattern, and determining performance of the storage device in relation to each required data transfer rate based on the actual data transfer time for the data.
