A PowerEdge R840 server with RM5 Series value SAS and CD5 Series data center NVMe SSDs processed more operations per second and delivered better performance per dollar than the same server with enterprise SATA SSDs

Business moves at a lightning-fast pace. Shouldn’t the drives in your data center do the same? SATA SSDs, once embraced as an affordable flash storage option, haven’t increased their transfer speeds in over ten years.1 For a faster storage option, KIOXIA has introduced the RM5 Series of value SAS SSDs and the CD5 Series of data center NVMe™ SSDs. Can these drives compete with enterprise SATA drives on performance as well as cost?
We set up a Dell EMC™ PowerEdge™ R840 server with three different drive configurations: current-generation enterprise SATA SSDs, value SAS SSDs, and data center NVMe SSDs. To measure database performance, we ran a 100% read workload on MongoDB®, a popular document-based database used to access and analyze unstructured data. The configuration with value SAS drives from KIOXIA provided 106 percent more operations per second (OPS) than the configuration with SATA drives. Data center NVMe drives improved performance even further, producing 137 percent more OPS than the SATA-based configuration. Value SAS and data center NVMe SSDs also offered up to 57 percent better response times and provided up to 132 percent better database performance per dollar than the enterprise SATA SSDs we tested.
Value SAS and data center NVMe SSDs from KIOXIA offer storage options that can keep up with the pace of business. Welcome to life after SATA.
