the launch of a high-performance PCIe 4.0 NVMe SSD: PM9C1a. Its controller based on Samsung’s 5nm process and the seventh-generation V-NAND flash memory technology will provide desktops and laptops with higher gaming and computing performance.
“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.”
PM9C1a series SSD adopts PCIe 4.0 x4 interface, provides products with M.2 2280/2242/2230 specifications, and the storage capacity can be selected from 256GB, 512GB, and 1TB. Its maximum sequential read speed is 6000 MB/s, maximum sequential write speed is 5600 MB/s, maximum random read is 900K IOPS, and maximum random write is 1M IOPS.
Compared to its predecessor (PM9B1), the PM9C1a offers 1.6 times the sequential read speed and 1.8 times the sequential write speed, according to Samsung
. In addition, PM9C1a also improves energy efficiency by 70% compared with the previous generation, which means that the new SSD can handle the same number of tasks with less power. At the same time, when the laptop enters standby mode, the power consumption of the SSD will be reduced by about 10%.
PM9C1a also supports the Device Identity Composition Engine (DICE) security standard developed by the Trusted Computing Group (TCG). DICE securely generates cryptographic keys inside the SSD, providing device authentication to prevent targeted attacks through vulnerabilities in the vendor network, and verification of any firmware parameter tampering.
