Abstract
A host may not have a large enough internal non-volatile memory to store generated data, such as video. In such situations, the host can store the data in an external data storage device, such as an external solid-state drive (SSD). However, if the storage rate of the external data storage device drops below the rate at which the host is generating and sending the data to the external data storage device, data loss can occur. To help avoid this situation, the host can use a dual-write method in which a portion of the data is both sent to the external data storage device for storage and written in the host's internal non-volatile memory. That way, if the portion of the data sent to the external data storage device is lost, the portion of the data can be resent from the host's internal non-volatile memory.
