Samsung PM9A3 E1.S SSD Announced

Samsung has announced the PM9A3 SSD at the OCP Virtual Summit keynote, which features an SNIA-based E1.S form factor model and full PCIe Gen 4 support. This allows it to leverage the production efficiencies of the company’s sixth-generation (1xx-layer), three-bit V-NAND. In addition, Samsung has also introduced a comprehensive reference design for its E1.S-based storage system. Also reported at the keynote was a new approach to open-source multi-industry storage collaboration, which highlighted the development of an open-source platform connected to cloud-scale infrastructure deployments.
