Data Storage Device and Method for Host Multi-Command Queue Grouping Based on Write-Size Alignment in a Multi-Queue-Depth Environment

A method comprising:

• performing the following in a host in communication with a data storage device, wherein the data storage device comprises a volatile memory and a non-volatile memory:
• receiving, from the data storage device, a write-alignment size;
• creating a command group to satisfy the write-alignment size;
• sending an indication to the data storage device that an amount of data associated with the command group satisfies the write-alignment size;
• and
• sending the amount of data to the data storage device;
• wherein the data storage device is configured to program the non-volatile memory with the amount of data without first storing the amount of data in the volatile memory, since a capacity of the volatile memory is less than the amount of data.

A data storage device comprising:

• a volatile memory;
• a non-volatile memory;
• means for providing a host with a write-step size for the non-volatile memory;
• means for receiving an assurance from the host that the host will provide the data storage device with an amount of data to satisfy the write-step size;
• and
• means for programming the non-volatile memory without first verifying that the amount of data to satisfy the write-step size was received from the host and stored in the volatile memory, since a capacity of the volatile memory is less than the write-step size.
