Another advantage the WD740GD had over its predecessor was Tagged Command Queuing, a feature that had previously been available only in SCSI drives. Command queuing resulted in a notable increase in the WD740GD's multi-user performance—a key discipline where its predecessor failed compared to SCSI drives. However, enabling command queuing on the WD740GD resulted in a performance decrease in single-user scenarios. It is worth noting that , only a few SATA controllers could fully support command queuing. This drive became immensely popular in high-end gaming systems because of these features.
