Samsung announces PCIe Gen4 NVMe SSD with 5nm PM9C1a controller and 7th Gen V-NAND

Samsung Electronics Unveils High-Performance PC SSD That Raises Everyday Computing and Gaming to a New Level

Built with a market-leading 5nm controller and seventh-generation V-NAND, the PM9C1a will enable a new level of everyday PC efficiency while also handling demanding computing and gaming tasks

Samsung Electronics today announced production readiness of a high-performance PCIe 4.0 NVMe SSD, the PM9C1a. Integrated with a new controller based on Samsung’s cutting-edge 5-nanometer (nm) process and the company’s seventh-generation V-NAND technology, the PM9C1a will provide elevated computing and gaming performance in PCs and laptops.

“Our new PM9C1a SSD will deliver a robust combination of superior performance, greater power efficiency and increased security, which are the qualities that matter most to PC users. We are committed to creating storage that satisfies the diverse and changing market requirements as we continue to advance innovation in the PC SSD space.”

— said Yong Ho Song, Executive Vice President of Memory Solution Product & Development at Samsung Electronics

With top-tier speeds, the PM9C1a SSD is ideal for everyday use as well as for more demanding computing and gaming applications. Leveraging the PCIe 4.0 interface, Samsung’s PM9C1a boasts a 1.6x faster sequential read speed and a 1.8x faster sequential write speed than its previous storage offering (PM9B1), reaching 6,000 megabytes per second (MB/s) and 5,600MB/s, respectively. Additionally, random read and write speeds can support up to 900K input/output operations per second (IOPS) and 1,000K IOPS, respectively.

The PM9C1a also offers up to 70% more power efficiency per watt than its predecessor. This means the new SSD can handle the same amount of tasks using significantly less power. Furthermore, when a notebook PC goes into standby mode, the SSD will use approximately 10% less power.

To address the rising need for stronger security measures, the PM9C1a features powerful security. The SSD supports the Device Identifier Composition Engine (DICE) security standard created by the Trusted Computing Group (TCG), a global organization that develops open standards for computing security. DICE securely generates cryptographic keys inside the SSD, providing device authentication to protect against supply chain attacks — cyberattacks that target companies through vulnerabilities in their supplier network — as well as attestation to prevent any firmware tampering.

Samsung’s PM9C1a SSDs will be available in 256GB, 512GB and 1TB storage capacities in a M.2 form factor (22mm x 30mm, 22mm x 42mm, 22mm x 80mm).
