SK Hynix Unveils High-Performance SSD Tailored for AI PCs

SK Hynix, Samsung's South Korean counterpart, has introduced the high-performance PCIe Gen 5.0 SSD, PCB01, designed for on-device AI PCs. This cutting-edge SSD offers lightning-fast sequential read and write speeds of 14GB and 12GB per second, respectively, as well as 4K random read and write rates of 2 million IOPS. These exceptional speeds enable near-instant completion of large language model (LLM) training and inference tasks.

The PCB01 also demonstrates a 30% improvement in power efficiency compared to its predecessors, enhancing stability during extensive AI computing tasks. It leverages SLC caching technology to optimize performance by placing single-level cells in specific parts of the NAND for faster computing. Additionally, it incorporates a root of trust (ROT) solution to defend against cybersecurity threats and safeguard personal data.

SK Hynix intends to commence mass production and release the PCB01 later this year in three capacities: 512GB, 1TB, and 2TB. Primarily targeting OEMs, these bare drives are part of the company's new Alistar platform, featuring an 8-channel interface and 238-layer TLC NAND technology. Notably, the PCB01 does not include a heatsink, potentially making it more budget-friendly than competitors like Crucial’s T705.

Key Takeaways

  • SK Hynix launches PCIe Gen 5.0 SSD PCB01 for AI PCs with impressive read and write speeds.
  • The SSD features 4K random read/write rates of 2 million IOPS, ideal for LLM training and inference.
  • PCB01 incorporates SLC caching and a root of trust solution for enhanced performance and security.
  • The SSD will be available in 512GB, 1TB, and 2TB capacities, initially targeting OEMs.
  • SK Hynix aims to strengthen its position as a top AI memory provider with this new product.


SK Hynix's new PCB01 SSD, with its advanced PCIe Gen 5.0 technology, sets the stage for the company to dominate the AI PC market, potentially impacting Samsung and Crucial. This move accelerates AI processing, influencing software development and data security industries. The absence of a heatsink could reduce costs, benefiting consumers and OEMs. In the short term, SK Hynix gains market share, while in the long term, it solidifies its AI memory leadership, potentially reshaping global tech supply chains.

Did You Know?

  • PCIe Gen 5.0 SSD:
    • PCIe Gen 5.0 is the latest standard in the PCIe interface series, offering significantly higher data transfer rates compared to previous generations. Supporting speeds up to 32 GT/s, double that of PCIe Gen 4.0, this advancement is crucial for devices like AI PCs that require high-speed data processing and transfer.
  • 4K Random Read/Write Rates:
    • 4K random read/write rates indicate the SSD's performance when accessing small blocks of data in a random manner. High 4K random read/write rates are vital for tasks involving numerous small file accesses, such as database operations and on-device AI processing, including LLM training and inference. The 2 million IOPS mentioned reflects the SSD's capability to handle a high volume of small, random I/O operations efficiently.
  • Root of Trust (ROT) Solution:
    • A Root of Trust (ROT) solution is a security feature that establishes a secure starting point within a device's hardware or firmware. This foundational security measure ensures secure operation from the initial boot-up sequence, protecting against unauthorized access and potential cybersecurity threats. In the context of the PCB01 SSD, the ROT solution aims to safeguard personal data and maintain the integrity of AI computing tasks by preventing unauthorized modifications and ensuring secure boot processes.
