Data Storage Device and Method for Buffer Occupancy-Based Data Placement to Avoid Video Loss

A host comprising:

• a non-volatile memory;
• a primary buffer;
• a secondary buffer;
• and
• one or more processors, individually or in combination, configured to:
• determine whether an available capacity of the primary buffer is below a threshold;
• in response to determining that the available capacity of the primary buffer is not below the threshold, send a portion of data generated by the host to the primary buffer for transfer to an external data storage device for storage;
• and
• in response to determining that the available capacity of the primary buffer is below the threshold:
• send the portion of the data generated by the host to the secondary buffer for transfer to the non-volatile memory for storage;
• determine whether the available capacity of the primary buffer is above the threshold;
• and
• in response to determining that the available capacity of the primary buffer is above the threshold, send the portion of the data stored in the non-volatile memory to the primary buffer for transfer to the external data storage device for storage.
