Explanation

FastWrite is correct because it leverages the iSCSI/SCSI protocol's "First Burst Enabled" feature, which allows an initiator to send the first burst of write data immediately alongside the SCSI command - without waiting for the target's "Ready to Transfer" (R2T) signal. In a standard write flow, the initiator must first send the command, receive an R2T acknowledgment, and then send data, requiring at least two round trips. FastWrite collapses this into a single burst, cutting link-level write interactions by approximately half. No distractors are presented in this question, so comparison analysis does not apply here.

Memory tip: Think of FastWrite as "fire and forget" - instead of asking permission (R2T) before sending data, the initiator fires the data along with the command in the first burst, making writes fast by skipping the handshake round trip.
