A Data Storage Device (DSD) includes a plurality of solid-state memories for storing data and a controller configured to receive a packet from a host including a command to read or write data in a solid-state memory of the plurality of solid-state memories and a header to communicate between the host and the DSD. The header in the packet is changed into an internal header to communicate between the controller and the solid-state memory. An internal command and the internal header are sent to the solid-state memory to perform the command.

Ethernet in data storage device

A method and apparatus is disclosed for using supervised learning with closed loop feedback to improvement of output consistency for memory arrangements, such as a solid state drive.

Supervised learning with closed loop feedback to improve input output consistency of solid state drives

A Data Storage Device (DSD) includes a plurality of storage areas for storing data. A command is received from a host to write data or read data in the DSD, and a storage area is identified for writing the data or reading the data for the command. An internal command is sent to the identified storage area to write the data or read the data for the command using an Ethernet protocol. In another aspect, a command is received from a controller of a DSD to copy data from one storage area to a different storage area of the DSD. The different storage area is identified using an address included in the command received from the controller, and the data for the command is read from the storage area. The data is sent to the different storage area using the address included in the command received from the controller.

A non-volatile memory (NVM) system receives host requests that each specify a memory operation to be performed by the NVM system, the specified memory operations including read operations and write operations, and performs a set of operations for each memory operation specified by a received host request. The set of operations performed for each such memory operation include: initiating performance the memory operation; determining a throttle interval for the memory operation in accordance with at least a first factor, corresponding to available space in a write cache of the non-volatile memory system, and a second factor, corresponding to a metric corresponding to prevalence of write operations in the memory operations specified by the received host requests; and returning to the host system a response associated with the memory operation at a time no earlier than a start time associated with the memory operation plus the determined throttle interval.
