Abstract
Implementations disclosed herein provide a method comprising comparing high-latency data sectors of a storage band, the high-latency data sectors having latency above a predetermined threshold, with target sectors for storing new data to determine one or more of the high-latency data sectors that may be skipped during retrieval of at-rest data from the storage band.
Claims20
A method comprising:
- comparing high-latency data sectors of a storage band with target sectors to determine one or more of the high-latency data sectors that may be skipped during retrieval of at-rest data from the storage band.
An apparatus, comprising:
- a host configured to send a read request to a storage device;
- and
- the storage device configured to compare high-latency data sectors of a storage band with target sectors to determine one or more of the high-latency data sectors that may be skipped during retrieval of at-rest data from the storage band.
One or more non-transitory computer-readable storage media encoding computer-executable instructions for executing on a computer system a computer process that compares high-latency data sectors of a storage band, the computer process comprising:
- comparing high-latency data sectors of a storage band with target sectors for storing new data;
- and
- determining one or more of the high-latency data sectors that may be skipped during retrieval of at-rest data from the storage band.
