Samsung Electronics announces its new PM9C1a 5nm Controller High-performance SSD

Samsung Electronics Co., Ltd., the world leader in advanced memory technology, this thursday announced that the PM9C1a, a high-performance PCIe 4.0 NVMe SSD, is now in production. The PM9C1a will provide enhanced computing and gaming performance in PCs and laptops thanks to a new controller based on Samsung’s cutting-edge 5-nanometer (nm) process and the company’s seventh-generation V-NAND technology.

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

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

The PM9C1a has up to 70% higher power efficiency per watt than its predecessor.

This means that the new SSD can perform the same number of tasks while using significantly less power. Furthermore, when a notebook PC enters standby mode, the SSD consumes about 10% less power.

The PM9C1a has powerful security to meet the growing demand for stronger security measures. The SSD supports the Trusted Computing Group’s (TCG) Device Identifier Composition Engine (DICE) security standard, which was developed by a global organisation that develops open standards for computing security.

DICE generates cryptographic keys inside the SSD in a secure manner, providing device authentication to protect against supply chain attacks — cyberattacks that target companies via vulnerabilities in their supplier network — as well as attestation to prevent any firmware tampering. Samsung’s PM9C1a M.2 SSDs will be available in 256GB, 512GB, and 1TB storage capacities (22mm x 30mm, 22mm x 42mm, 22mm x 80mm).
