SAS dual-port advantage for fault tolerance

SAS features dual porting for redundancy, eliminating single points of failure and allowing for higher reliability and performance. Although SATA 6Gbps SSDs provide high-performance and affordable storage, the lack of dual-port support makes them unsuitable for dual-controller environments. By installing a SATA SSD with the QDA-SA2 into a dual-controller Enterprise ZFS NAS or a dual-controller server, the SATA SSD can share these SAS dual-port advantages to ensure a high-availability, fault-tolerant enterprise storage environment.
