Samsung electronics announced about the production maturity of new high-performance SSDs for PC: PM9C1a models with PCIe 4.0 interface and NVMe protocol support. Equipped with 5nm Samsung controllers and 7th generation V-NAND memory (176 layers), the drives will take everyday PC performance to a new level and will not give in to demanding computing and gaming tasks.
New items will be available in capacities of 256, 512 and 1000GB in different versions of the M.2 form factor: 22×30mm, 22×42mm and 22×80mm. With a new controller and PCIe 4.0 interface, the Samsung PM9C1a SSDs offer 1.6X faster sequential read speed and 1.8X faster sequential write speed than the previous PM9B1 model. At the same time, the reading speed reaches 6000 MB / s, and the writing speed reaches 5600 MB / s. Productivity reaches 900 thousand and 1000 thousand IOPS for random read or write operations.
No less important was increasing the energy efficiency of new drives. The PM9C1a models deliver 70% more performance per watt than their predecessors. In other words, the new SSD can do the same amount of work while using significantly less power. When the laptop finally goes into standby mode, such a drive consumes about 10% less power.
In addition, PM9C1a drives support the Trusted Computing Group’s (TCG) Device Identifier Composition Engine (TCG) security standard. It generates embedded cryptographic keys to protect against supply chain attacks. Such a solution protects against cyberattacks in the process of delivering the SSD to the consumer if the suppliers have vulnerabilities. In particular, this will help avoid fake firmware and ensure the authenticity of products. The company did not disclose the timing of the start of sales of new SSDs and the price of the issue.
