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.

Host and dual write method for avoiding data loss when writing to an external data storage device

Some data storage devices have a plurality of memory dies that can be read in parallel for certain types of read requests. Read requests pertaining to a garbage collection operation are often generated sequentially and, thus, are not eligible for parallel execution in the memory dies. In an example data storage device presented herein, such read requests are consolidated and sent to the memory for execution in parallel across the memory dies.
