Upgrading Local Server Transactional Database Performance with KIOXIA PM7 Series SSDs

This performance brief presents a comparison of SSD performance and system utilization between KIOXIA PM7-V Series 24G SAS SSDs and SATA SSDs from a leading provider, using Microsoft SQL Server as a database to simulate transactional workloads. The brief outlines the limitations of SATA SSDs, particularly their 6 Gb/s data transfer rate, which can bottleneck transactional database workloads. In contrast, the 24G SAS interface offers significantly higher bandwidth, enabling improved transaction processing capabilities. The document details the testing methodology, including the metrics recorded such as average database transactions, read and write throughput, latency, and power utilization. Results indicate that KIOXIA PM7-V Series SSDs achieved a 3.4x increase in transactions per minute compared to SATA SSDs, alongside substantial improvements in read and write throughput and latency. Additionally, the brief discusses the implications of these findings for various applications, including databases and cloud services, emphasizing the performance benefits of upgrading to 24G SAS SSDs.
