According to the Serial ATA International Organization (SATA-IO), there are no plans to extend SATA bandwidth beyond its current 6Gb/s transfer rate.3 SAS SSDs, by contrast, have a roadmap that extends into 2029, including plans for faster speeds.4
With their RM5 Series value SAS SSDs, KIOXIA has introduced a SAS option that provides better transactional database performance per dollar.5
According to KIOXIA, value SAS SSDs offer a 12Gb/s connection and provide “better performance, reliability, and features than enterprise SATA SSDs.”6 The RM5 Series includes both read-intensive and mixed-use models to give enterprises flexibility to choose the most appropriate drive for their workloads. In our VMware vSAN cluster, we used 3.84TB read- intensive drives for our capacity tier and 960GB mixed- use drives for our cache tier to handle the more write- intensive I/O activity in our workload.
