SK hynix unveiled a new consumer product based on its latest solid-state drive (SSD), PCB01, which boasts industry-leading performance levels at GPU Technology Conference (GTC) 2024. Hosted by NVIDIA in San Jose, California from March 18–21, GTC is one of the world’s leading conferences for AI developers.

Applied to on-device AI PCs, PCB01 is a PCIe fifth-generation SSD which recently had its performance and reliability verified by a major global customer. After completing product development in the first half of 2024, SK hynix plans to launch two versions of PCB01 by the end of the year which target both major technology companies and general consumers.

Offering the industry’s highest sequential read speed of 14 gigabytes per second (GB/s) and a sequential write speed of 12 GB/s, PCB01 doubles the speed specifications of its previous generation. This enables the loading of LLMs required for AI learning and inference in less than one second. To make on-device AIs operational, PC manufacturers create a structure that stores an LLM in the PC’s internal storage and quickly transfers the data to DRAMs for AI tasks. In this process, the PCB01 inside the PC efficiently supports the loading of LLMs. SK hynix expects these characteristics of its latest SSD to greatly increase the speed and quality of on-device AIs.

PCB01 also offers a 30% improvement in power efficiency compared to its previous generation so it can effectively manage power from large-scale AI computations. In addition, SK hynix has applied single-level cell (SLC) caching technology to the product which enables some of the cells—the storage areas of NAND—to operate as SLCs with fast processing speeds. The technology allows selected data to be quickly read and written, speeding up the operation of AI services and general PC operations.

Jae-yeun Yun, head of NAND Product Planning and Enablement at SK hynix, stated: “PCB01 will not only be highlighted for its use in AI PCs, but this high-performing product will also receive significant attention in the gaming and high-end PC markets,” he said. “Our much-anticipated product will allow us to solidify our position as the global no.1 AI memory provider not only in the HBM field but also in the on-device AI area.”

Alongside its PCB01-based product, SK hynix also introduced its next-generation flagship technologies and solutions at GTC 2024 including its 36 GB 12-layer HBM3E, CXL, and GDDR7. The display of HBM3E, the industry’s first fifth-generation HBM solution, follows the company’s announcement that it has begun volume production of the product. In addition, GDDR7 attracted much attention for doubling its bandwidth and improving its power efficiency by 40% compared to its predecessor GDDR6.

On top of presenting its world-class portfolio, SK hynix also held presentation sessions at GTC 2024. Technical Leader Seoyeong Jeong of HBM Marketing gave a talk titled “The Outlook of the HBM Market” where she shared insights on the importance of AI memory and its core technologies.
