Patent number: 9280472Abstract: A combination of a host system and a storage system is disclosed that facilitates improved responsiveness of the host system to user requests. In one embodiment, the host system includes a cache management module, a partitioning module, and a driver. The cache management module determines write data to cache to a dedicated zone of a hard disk media of the storage system. The partitioning module partitions the hard disk media into one partition including the dedicated zone and another partition not including the dedicated zone. The driver transmits storage access commands to the storage system to cache data in and retrieve cached data from the one partition. Thereby, the host system can access the write data from the hard disk media more quickly than if the write data were cached in and accessed from another zone of the hard disk media.Type: GrantFiled: March 13, 2013Date of Patent: March 8, 2016Assignee: Western Digital Technologies, Inc.Inventors: Dean V. Dang, Colin W. Morgan, Robert S. Cohn, Theodore E. Deffenbaugh, Kent W. Gibbons

Patent number: 9268487Abstract: A data storage device including a solid state memory comprising logical block addresses (“LBAs”) corresponding to boot data accessed by a host during a boot process, and a controller. The controller can be configured to determine the LBAs corresponding to the boot data, and determine whether the solid state memory has reached an end-of-life condition. Upon determining that solid state memory has reached an end-of-life condition, the controller can restrict the host to write to the LBAs corresponding to the boot data during a boot process, and set the solid state memory into a read only mode when the boot process is complete.Type: GrantFiled: May 12, 2014Date of Patent: February 23, 2016Assignee: Western Digital Technologies, Inc.Inventors: Kent W.
