QStor Controllers
QStor is the only controller that has All-Queuing hardware, a feature that maximizes queuing performance, for both ATA-7 Tagged Command Queuing (TCQ) and SATA-II Native Command Queuing (NCQ) drives -- and dramatically increases command IO throughput. For example, a four-port configuration typically achieves in excess of 850 IOPS under heavy loads in file server applications.
