A PowerEdge MX solution with RM5 Series value SAS SSDs processed more simulated customer orders, responded in less time, and provided better per-system value than the same solution with enterprise SATA SSDs
Dell EMC PowerEdge MX-based vSAN cluster running a transactional database workload
You wouldn’t set out on a road trip with an outdated map. Yet many businesses are still relying on SATA SSDs, a technology that hasn’t increased its transfer speed of 6Gb/s in over ten years.1 Value SAS SSDs from KIOXIA offer businesses a connection speed that’s twice as fast.2 But can RM5 Series value SAS SSDs compete with enterprise SATA SSDs on price as well as performance?
We used hands-on testing to find out, setting up a VMware vSAN™ cluster on a Dell EMC™ PowerEdge™ MX server with two different drive configurations: enterprise SATA SSDs, and RM5 Series value SAS SSDs. On each set of drives, we configured a virtualized environment to run mixed read/write transactional database workloads that simulated customer purchases from an online store. The configuration with value SAS SSDs processed 40 percent more orders per minute, responded in roughly half the time, and delivered 45 percent more transactional database performanceper dollar than the enterprise SATA SSDs we tested.
With value SAS SSDs from KIOXIA, your business can navigate toward future growth. Welcome to life after SATA.

SATA-IO states on their FAQ page that “there are no plans to extend SATA bandwidth beyond the current 6Gb/s transfer rate” (“SATA-IO Frequently Asked Questions,” accessed October 3, 2019, https://sata-io.org/sata-io-frequently-asked-questions).
