Samsung intros new SSD with higher efficiency, performance, security


Last updated: January 12th, 2023 at 13:09 UTC+01:00

Samsung Electronics is preparing to release a new high-performance PCIe 4.0 NVME SSD for PCs and laptops. The company announced the sequel to the PM9B1 SSD today, called PM9C1a, which boasts several improvements over the predecessor in terms of performance and power efficiency.

The PM9C1a is based on Samsung’s seventh-generation V-NAND technology and features a new controller manufactured on the company’s 5nm process. Because of these upgrades, the new PCIe 4.0 NVMe SSD boasts up to 70% higher power efficiency per watt than its predecessor. In addition, the SSD uses 10% less power when the laptop goes into standby mode.

Powerful security, better performance, three storage options

Aside from energy efficiency gains, Samsung’s new PM9C1a SSD also boasts 1.6x faster sequential read speeds and 1.8x faster sequential write speeds compared to the PM9B1. The tech giant says that the new SSD can reach 6,000 MB/s and 5,600 MB/s in sequential read/write speeds, respectively, while random read and write speeds can support up to 900K and 1,000K IOPS (input/output operations per second), respectively.

The new SSD also supports the Device Identifier Composition Engine (DICE) standard developed by the Trusted Computing Group (TCG). This security system generates cryptographic keys inside the SSD for device authentication and protection against cyberattacks that target companies through vulnerabilities in their supply network.

Samsung will release the PM9C1A M.2 SSD in three storage configurations and three sizes: 256GB (22 x 30mm), 512GB (22 x 42mm), and 1TB (22 x 80mm). However, exact release dates and pricing details have not been confirmed. Today, Samsung announced “production readiness” for the SSD, which means it could hit the shelves globally relatively soon.
