Principled Technologies Compares Performance of Value SAS and Data Center NVMe SSDs from Toshiba Memory vs. SATA SSDs in Dell EMC PowerEdge R840, R740xd, and MX Servers

Durham, NC, April 30, 2019 --(PR.com)-- SATA SSDs, once embraced by enterprises as an affordable flash storage option, have not increased their transfer speeds in over ten years. (Footnote 1) Now Toshiba Memory has introduced the RM5 Series of value SAS SSDs and the CD5 Series of data center NVMe SSDs, both of which claim faster transfer speeds than SATA SSDs. Principled Technologies tested value SAS SSDs, data center NVMe SSDs, and SATA SSDs across three different workloads and Dell EMC PowerEdge server platforms to gauge whether the drives from Toshiba Memory could boost database workload performance and provide performance-per-dollar cost savings versus the SATA SSDs.

According to the report, “The configuration with value SAS drives from Toshiba Memory 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.”

According to the report, “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.”

According to the report, “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 performance per dollar than the enterprise SATA SSDs we tested.”
