A data storage device includes a write cache, a non-volatile memory, and a controller coupled to the write cache and to the non-volatile memory. The controller is configured to, responsive to receiving a command to flush particular data from the write cache, attempt to fill a write block of data using the particular data and pending data obtained after receipt of the command.

Systems and methods of write cache flushing

In one aspect, a system for indexing transactions over a plurality of communication lines is described. In various embodiments, the system includes a host controller and a plurality of storage devices in communication with one another. Each of the storage devices is configured to store data. The communication lines facilitate communications between the host controller and the plurality of storage devices. A selected one of the storage devices is configured to function as a transaction indexer to monitor the communication lines and index and store selected transaction information associated with operations that occur over the communication lines. While the host controller may be arranged to configure the transaction indexer, the transaction monitoring, indexing and storing are performed substantially automatically by the transaction indexer without requiring further instructions from the host controller.

Storage device with transaction indexing capability

In one aspect, a system for indexing transactions over a shared bus is described. In various embodiments, the system includes a host controller and a plurality of storage devices in communication with the bus. Each of the storage devices is configured to store data. The bus facilitates communications between the host controller and the plurality of storage devices. A selected one of the storage devices is configured to function as a transaction indexer to monitor the bus and index and store selected transaction information associated with operations that occur over the bus. While the host controller may be arranged to configure the transaction indexer, the transaction monitoring, indexing and storing are performed substantially automatically by the transaction indexer without requiring further instructions from the host controller.
