Write Completion Pacing For Unbalanced Command Length

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller comprises:
• a completion manager configured to send completion messages to a host device for executed commands received from the host device;
• and
• a scheduler, wherein the scheduler is configured to:
• queue a command received from the host device having a size less than or equal to a threshold size in a first queue;
• queue a command received from the host device having a size greater than the threshold size in a second queue;
• determine to execute, based on a command size tracker value being less than or equal to a threshold value, a command from the first queue or, based on the command size tracker value being greater than the threshold value, a command from the second queue;
• and
• execute the command from the first queue or the command from the second queue based on the determining.

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, wherein the controller is configured to:
• determine that a command size tracker value exceeds a threshold value, wherein:
• the command size tracker value is increased by a value representative of a size of a command executed from a first queue;
• commands stored in the first queue have a size less than or equal to a threshold size;
• the command size tracker value is decreased by a value representative of a size of a command executed from a second queue;
• commands stored in the second queue have a size greater than the threshold size;
• and
• the value representative of the size of the command executed from the first queue is less than the value representative of the size of the command executed from the second queue;
• and
• execute a command from the second queue when the command size tracker value exceeds the threshold value.
