| Zusammenfassung: | Delivering different data response time performance from a plurality of disk drives having similar performance characteristics includes subdividing each disk drive platter of the disk drives into at least two separate portions, where a first portion has a first average response time and the second portion has a second average response time that is greater than the first average response time and includes placing data that is relatively frequently accessed in the first portion of the disk platters of the disk drives to provide a subset of data having a relatively higher data response time performance than other data. Data having a relatively lower data response time performance may be placed on disk drives containing data having a relatively higher data response time performance. |
