The SK Hynix PCB01: The Engine Powering Next-Gen SSDs

SK hynix introduced a consumer device based on its newest SSD, PCB01, with industry-leading performance at GPU Technology Conference (GTC) 2024. GTC, an AI development conference, is held in San Jose, California by NVIDIA from March 18–21.

A significant international client has validated the performance and dependability of PCB01, a PCIe fifth-generation SSD used in on-device AI PCs. SK hynix aims to introduce two PCB01 models for key technology businesses and customers by the end of 2024 after finishing product development in the first half.

1. On-device AI: AI computation and inference on devices like smartphones and PCs, unlike cloud-based AI services.

2. PCIe: A high-speed input/output interface with a serialization format used on digital device motherboards.

Designed with AI computers in mind, and able to load LLMs in under one second

With a sequential read speed of 14 gigabytes per second (GB/s) and a sequential write speed of 12 GB/s, PCB01 surpasses its predecessor’s speed standards by twice. This allows the LLMs needed for AI learning and inference to be loaded in less than a second.

3. Large language model (LLM): Language models that have been created via extensive data training are crucial for generative AI tasks including text creation, summarization, and translation.

PC makers provide a framework that swiftly moves data from internal PC storage to DRAMs for AI operations, storing an LLM in order to enable on-device AIs. The PC’s internal PCB01 allows the loading of LLMs effectively throughout this operation. SK Hynix anticipates that these features of their most recent SSD will significantly improve the quality and performance of on-device AIs.

Additionally, PCB01 provides a 30% boost in power efficiency over its predecessor, enabling it to efficiently manage power from complex AI calculations. Furthermore, SK Hynix has included single-level cell (SLC) caching technology into the device, allowing some NAND cells in the storage regions to function as SLCs with quick processing rates. The technology accelerates the operation of AI services and standard PC operations by enabling the fast reading and writing of specific data.

4. Single-level cell (SLC): Memory cell type utilized in NAND flash; each SLC may hold a single bit of data. A memory cell may become a multi-level cell (MLC), a triple-level cell (TLC), and so on depending on how much data it can store. Although more data may be stored in the same space, stability and performance suffer. SLC expedites the processing of chosen data.

Chief of NAND Product Planning and Enablement at SK Hynix, Jae-yeun Yun, said: “This high-performing product will receive significant attention in the gaming and high-end PC markets, in addition to being highlighted for its use in AI PCs.” “They will be able to maintain their position as the world’s leading supplier of AI memory, not just in the HBM space, thanks to their eagerly awaited product.”

At GTC 2024, SK Hynix unveiled its PCB01-based product in addition to its next-generation flagship technologies and solutions, which include its 36 GB 12-layer HBM3E, CXL, and GDDR7. After announcing volume production, and HBM3E, the industry’s first fifth-generation HBM solution, was shown. The GDDR7 was also lauded for double bandwidth and 40% power efficiency over GDDR6.

5. Compute Express Link (CXL): An integrated interface that links RAM, CPUs, GPUs, and accelerators.

6. GDDR7: The seventh generation of graphics memory, which enhances the speed and efficiency of GPU operation.

SK Hynix hosted presentation sessions at GTC 2024 in addition to showcasing its elite portfolio. HBM Marketing Technical Leader Seoyeong Jeong discussed the significance of AI memory and its fundamental technologies in a session titled “The Outlook of the HBM Market.”


What does PCB01 stand for?

With performance levels for on-device AI PCs that dominate the market, SK Hynix has released a new PCIe Gen 5 SSD called the PCB01.

What advantages does the PCB01 offer?

With the fastest sequential read and write speeds in the industry (14 GB/s and 12 GB/s, respectively), the PCB01 makes it possible for large language models (LLMs) to be loaded more quickly for AI workloads.

When is the PCB01 going to be accessible?

By the end of 2024, SK Hynix intends to release two iterations of PCB01, aiming to please both mainstream consumers and significant IT businesses.

What applications will the PCB01 be used for?

The PCB01 is designed with AI PCs in mind, and it should be useful for activities like AI learning and inference that need for quick data processing.
