A PowerEdge R740xd server with drives from KIOXIA achieved better transactional database performance at a lower cost than the same server with enterprise SATA SSDs

For years, businesses looking for lower-cost, flash-level performance have defaulted to SATA SSDs. But with SATA SSD connection speeds limited to 6Gb/s, businesses are increasingly seeking cost-effective ways to improve performance. Now KIOXIA has introduced the RM5 Series value SAS SSDs and CD5 Series data center NVMe™ SSDs, both of which offer faster transfer speeds than SATA SSDs. Together with the Dell EMC™ PowerEdge™ R740xd server we tested, these drives from KIOXIA also provided a better performance-to-cost ratio than the SATA SSDs we tested.1
We configured a Dell EMC PowerEdge R740xd server with three types of drives: enterprise SATA SSDs, value SAS SSDs, and data center NVMe SSDs. Using a read- intensive transactional database workload, we tested the drives. The value SAS drive configuration boosted transactions per second (TPS) by up to 71 percent over the configuration with enterprise SATA drives. Data center NVMe drives pushed performance even further, delivering up to 115 percent more TPS than the SATA-based configuration. We also found that value SAS and data center NVMe drives delivered, respectively, up to 73 percent and 109 percent better transactional database performance per dollar than enterprise SATA drives.
With value SAS and data center NVMe SSDs from KIOXIA, your business might not have to choose between performance and affordability. Welcome to life after SATA.
