Explore a technical presentation from the Storage Developer Conference 2023 that delves into achieving Write Amplification Factor (WAF) of 1 using Flexible Data Placement (FDP) in NVMe SSDs. Learn what WAF=1 means for SSD performance and examine various example workloads that can achieve this optimal efficiency. Understand different Host side rule implementations for controlling deallocate and write behaviors, from simple circular FIFOs to large region deallocations and probabilistic overwrites. Follow along with illustrated NAND activity demonstrations to gain practical insights for implementing FDP in various use cases, complete with recommended write and deallocate guidelines for Host systems. Presented by Dan Helmick from Samsung, this 47-minute technical deep dive provides valuable knowledge for storage developers and engineers working with modern NVMe storage systems.
