Abstract
A data storage system includes a host having a write buffer, a memory region, a submission queue and a driver therein. The driver is configured to: (i) transfer data from the write buffer to the memory region in response to a write command, (ii) generate a write command completion notice; and (iii) send at least an address of the data in the memory region to the submission queue. The host may also be configured to transfer the address to a storage device external to the host, and the storage device may use the address during an operation to transfer the data in the memory region to the storage device.
