Group 1 - Huawei launched AI SSD products, including the Huawei OceanDisk EX/SP/LC series, with capacities reaching up to 122/245 TB, marking the largest single-disk capacity in the industry [1] - The AI SSD is optimized for AI workloads, combining multiple core technologies developed by Huawei, and is expected to be a key breakthrough for domestic SSDs [1] - The rapid proliferation of AI applications has led to exponential data growth, with the total global internet corpus increasing from 350 PB (text) to 154 ZB (multi-modal), highlighting the limitations of traditional storage media [1] Group 2 - The model training phase faces significant challenges, requiring 13.4 TB of memory and 168 cards for training a 671B model, which severely limits training efficiency and flexibility [1] - The model inference phase also struggles with slow performance, with an average time to first token (TTFT) of 1000 ms, which is twice that of American models, and a token per second (TPS) rate of only 25, significantly impacting user experience [2] - High-performance AI SSDs are becoming the industry choice, but overseas manufacturers dominate the SSD market, with Samsung, SK Hynix, Micron, Kioxia, and SanDisk leading the market share [2] Group 3 - Despite the current dominance of HDDs in server storage, the advantages of SSDs in AI scenarios, such as energy efficiency and low operating costs, are driving rapid penetration, with SSDs expected to account for 9%-10% of server storage solutions by 2024 [2] - The domestic market is predicted to gradually replace HDDs with large-capacity QLC SSDs, facilitating a transition from a "capacity-oriented" to a "performance and capacity dual-optimization" model [3] - As of June 2023, China's storage capacity reached 1680 EB, showing significant growth and advancements in external flash memory applications, particularly in finance, manufacturing, and internet sectors [3]
