<p>Duplicate copies of data may be stored in different sectors on the same track of a disk drive. When reading the data, the data may be read from the sector that passes under the read head soonest, thus decreasing data access latency. In some embodiments, the duplicate sectors may be equally spaced around the track. In some embodiments, the spin rate of the disk drive may be reduced to save power, with the increased data latency that would normally be created by the reduced spin rate to be at least partially offset by the decreased data latency created by using multiple copies of the data in the different sectors.</p> |
