The following is a simplified description of the prefetch/cache operation: Case A—read command is received and all of the requested logical blocks are already in the cache: 1. Drive transfers the requested logical blocks to the initiator. Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache: 1. The drive fetches the requested logical blocks from the disk and transfers them into a segment, and then from there to the host in accorda

5.2.4 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow you to back up the data before an actual failure occurs. Note. The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive failures. Each monitored attribute has been selected to monitor
