samsung on thursday introduced A new PM9C1a solid state drive that uses a controller built using 5-nanometer class process technology. An innovative production node has allowed Samsung to significantly reduce the power consumption of his SSD controllers, resulting in lower overall drive power consumption. The PM9C1a family is primarily targeted at mainstream and performance mainstream notebooks.
From a performance perspective, Samsung’s PM9C1a offers sequential read speeds of up to 6 GB/s and sequential write speeds of up to 5.60 GB/s. This seems pretty good for mainstream drives with a PCIe 4.0 x4 interface. Meanwhile, they offer up to 900K and 1M random read and write IOPS (respectively). This is in line with some of the best SSDs available today. Storage devices are available in 256GB, 512GB, and 1TB configurations, as well as M.2-2230, M.2-2242, and M.2-2280 form factors to meet the needs of various laptop designs. increase.
The 5nm based controller is one of the most interesting features of the new PM9C1a drives. Samsung’s new controller is made using one of the company’s 5nm-class nodes (although speculation, we presume this is his SF5 aka 5LPP). It is said to be significantly more power efficient than its predecessors and competitors made using thicker process technology. In fact, the majority of his latest SSD controllers are implemented using his 12nm-class manufacturing technology, so using a 5nm-class node seems like a very aggressive move to reduce power consumption. am. According to the company itself, its new PM9C1a drive offers “up to 70% more power efficiency per watt” than its predecessor, his PM9B1, and uses about 10% less power in idle mode.
Samsung should disclose all the specs of its controller for DRAM-less SSDs, but it should be sophisticated enough to handle the company’s latest type of V-NAND memory (presumably both 3D TLC and 3D QLC variants). It is expected that Supports advanced signal processing, error correction, and encryption techniques. In particular, this chip uses the Device Identifier Composition Engine (dice (opens in new tab)) A root of trust security standard designed to prevent firmware tampering and various attacks. DICE support is especially beneficial for PC OEMs, the target market for Samsung’s PM9C1a.
“Our new PM9C1a SSD offers a robust combination of superior performance, superior power efficiency and enhanced security – the qualities that matter most to PC users. As we continue to drive innovation in the field, we are committed to creating storage that meets the requirements of a diverse and changing market.”
