6 ST310014ACE Product Manual, Rev. D Note. These drives are designed to meet the seek times represented in this manual consistently. Physical seeks, regardless of mode (such as track-to-track and average), are expected to meet or exceed the noted values. However, due to the manner in which these drives are formatted, benchmark tests that include com- mand overhead or measure logical seeks may produce results that vary from these specifications. 1.7 Power specifications The drive receives D
