Explore optimal performance parameters for NVMe SSDs in this technical presentation from the Storage Developer Conference 2022. Dive into the intricacies of NVM Express® Command Set Specification's Section 5.8.2, examining crucial performance parameters like NPWG, NPWA, NPDG, NPDA, NOWS, NPRG, NPRA, and NORS. Understand the distinctions between various parameters, such as NPWG versus NOWS, and discover how both NAND and SSD Controller attributes influence parameter settings. Master the implementation of optimal performance parameters through practical examples of SSD sizing, super block fill sequences, and namespace configurations. Learn to fine-tune host software for maximum SSD performance while gaining insights into write performance optimization, deallocate parameters, and preferred read granularity settings. Presented by Dan Helmick from Samsung, this comprehensive technical discussion equips storage developers with essential knowledge for optimizing NVMe SSD performance in real-world applications.
