Watch a 38-minute conference talk from the Storage Developer Conference 2022 exploring how flash memory behavior impacts Quality of Service (QoS) in data center and enterprise SSDs. Gain deep insights into SSD performance metrics including IOPS, throughput, latency, and QoS measurements across different workload types. Learn about critical factors affecting QoS like workload patterns, host interface speed, IO stack, and NAND characteristics. Examine detailed QoS analysis methods using quantile and percentile measurements for read/write intensive operations, and understand how SSD firmware policies around over-provisioning, garbage collection and endurance influence performance. Through real-world use cases, discover why MLC-based SSDs excel at read-intensive applications while TLC-based drives better handle write-intensive and mixed workloads. Explore NAND timing parameters and their relationship to service quality, presented by Samsung Electronics specialists Yogesh Khurana and Ravishankar Singh. Read more
