摘要： A data storage system is disclosed that utilizes a high performance caching architecture. In one embodiment, the caching architecture utilizes a cache table, such as a lookup table, for referencing or storing host data units that are cached or are candidates for being cached in the solid-state memory. Further, the caching architecture maintains a segment control list that specifies associations between particular cache table entries and particular data segments. Such separation of activities related to the implementation of a caching policy from activities related to storing cached data and candidate data provides robustness and scalability while improving performance.

摘要： A disk drive including a disk configured to spin at a target spin speed, a servo core configured to access the disk, a first non-volatile memory configured to store a first initialization firmware, a second non-volatile memory configured to store a second initialization firmware, a first volatile memory, a second volatile memory, a non-volatile memory core configured to access the first non-volatile memory, and a main core. The main core is configured to load the second initialization firmware from the second non-volatile memory to the second volatile memory concurrently with the loading of the first initialization firmware from the first non-volatile memory to the first volatile memory by the non-volatile memory core, control the servo core to initiate spinning of the disk, and communicate with the non-volatile memory core to service host commands from the first non-volatile memory when the disk is not spinning at the target spin speed.

摘要： A disk drive is disclosed that utilizes multi-tiered solid state memory for caching data received from a host. Data can be stored in a memory tier that can provide the required performance at a low cost. For example, multi-level cell (MLC) memory can be used to store data that is frequently read but infrequently written. As another example, single-level cell (SLC) memory can be used to store data that is frequently written. Improved performance, reduced costs, and improved power consumption can thereby be attained.

摘要： Embodiments of solid-state storage system are provided herein which reduce processing delays for performance-sensitive commands. These performance-sensitive commands are typically read-write commands which can be transferred to the storage media by a high performance path to optimize responsiveness to the host. This high performance path can be enabled and disabled to prevent conflicts with commands processed via a low performance path.

摘要： A data storage system is disclosed that utilizes high performance media manager transport architecture. In one embodiment, solid-state memory is connected via a bridge interface and media manager transport architecture optimizes the transfer and throughput of data communicated across the bridge. Media transport manager architecture can support reordering and interleaving of storage access commands by using priority and staging mechanisms. Balanced load of solid-state memory, parallel execution of storage access operations, improved concurrency, and increased performance can be attained.
