Patent ID: 8838887

Claim:
A method of delivering different data response time performance from a plurality of disk drives having similar performance characteristics, comprising: subdividing at least one disk drive platter of the disk drives into at least two separate portions, wherein 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 for a first subset of data that is more frequently accessed than a second subset of data, placing the first subset of data in the first portion of the at least one disk platter of the disk drives, the first subset of data thereby being accessible faster than the second subset of data being stored on the second portion of the at least one disk platter having a higher data response time performance, wherein the first portion of the at least one disk drive platter is radially disposed between a center of the at least one disk platter and an outer edge of the at least one disk platter, and wherein the second portion is radially inside the first portion and radially outside the first portion.
