摘要： A hybrid drive is disclosed comprising a head actuated over a disk comprising a plurality of data tracks, and a non-volatile semiconductor memory (NVSM). An access command is received from a host, the access command identifying at least one target logical block address (LBA). When the target LBA is mapped to a target data track on the disk, the head is positioned over the target data track and an accumulated access time is updated for the target LBA. The accumulated access time is compared to a first threshold, and the target LBA is migrated to the NVSM in response to the comparison.

摘要： A system for storing video data includes a receiver configured to receive a stream of video data that includes a sequence of original transport packets. Each original transport packet has a first predetermined number of bytes including video data bytes. A first circuit is configured to add a second predetermined number of bytes to each original transport packet to create a modified transport packet having a third predetermined number of bytes. A storage medium is addressable on sector boundaries, wherein each sector has a predetermined number of user data bytes different from the first predetermined number of bytes. The first byte in a modified transport packet aligns with a first user data byte in a sector after a first predetermined number of sectors following a previous alignment.
