    摘要: A storage device comprising a storage media and a controller is disclosed. The controller is configured to receive access commands from a host, to write data to or read data from the storage media based on the access commands, to detect a trigger event, and, when the trigger event is detected, to throttle back the access commands from the host based on an amount of data in a cache.

    摘要: Systems and methods for performing refresh operations using write/read commands are provided. In one embodiment, a disk drive comprises a disk partitioned into a plurality of refresh zones, a head configured to write data to and read data from the disk, and a controller. The controller is configured to receive an access command, to read data from at least one of the refresh zones using the head in response to the access command, to check a condition of the read data, and to determine whether to refresh the at least one refresh zone based on the condition of the read data, wherein the read data includes data from a portion of the at least one refresh zone not being accessed by the access command.

    摘要: A disk drive is disclosed comprising a head actuated over a disk, a volatile semiconductor memory (VSM), and a command queue. A plurality of write commands received from a host are stored in the command queue, and write data for the write commands is stored in the VSM. A flush time needed to flush the write data from the VSM to the disk is computed, and the write data is flushed from the VSM to a non-volatile memory (NVM) in response to the flush time.

    摘要: A disk drive to implement write operations requested by a host is disclosed. The disk drive comprises: a disk having a plurality of tracks, wherein each track includes a plurality of physical data sectors; a head actuated over the disk; and control circuitry. The control circuitry is operable to determine if a write request from the host includes logic data that includes unaligned writes, and if so: coalesces nearby writes; performs a group read operation to create a plurality of groups; and performs a write operation to write the logic data to the physical data sectors based upon the plurality of groups, wherein the physical data sectors are written to the disk during a single revolution of the disk.

    摘要: A disk drive is disclosed comprising a disk having a host addressable area and a reserved area, an exception table stored in the reserved area, a head actuated radially over the disk to write data to the disk, and control circuitry coupled to the head. The control circuitry receives a first command from the host to write first host data into a first physical sector on the disk, wherein the first host data comprises an amount of data less than a full storage capacity of the first physical sector. The control circuitry detects an uncorrectable error while reading the first physical sector during read-modify-write operation, and indicates in the exception table that the first physical sector is a partial sector including valid and invalid logical block addresses (LBAs).
