BoI Approves B2.3bn Heat-Assisted Storage Project for WD Unit

Why It Matters

By pushing HDD capacities beyond 100 TB, the project secures Thailand’s leadership in high‑density storage essential for AI, cloud and data‑center expansion, while stimulating domestic high‑tech manufacturing and skilled‑labour development.

Key Takeaways

• BoI approves 2.3bn baht HAMR R&D for Western Digital.
• Goal: HDDs exceeding 100TB capacity by 2029.
• Project targets 60% local content, boosting Thai supply chain.
• Expected long‑term investment could reach 10bn baht.
• Supports AI, cloud, and data‑center growth regionally.

Pulse Analysis

Heat‑assisted magnetic recording (HAMR) represents a pivotal breakthrough in magnetic storage, using precise laser heating to temporarily lower media anisotropy and enable significantly smaller bit sizes. This technology directly addresses the long‑standing magnetic recording trilemma of density, stability and cost. Thailand, already responsible for roughly 80 % of global HDD manufacturing, is uniquely positioned to capitalize on HAMR’s potential, especially as Western Digital partners with U.S. and Japanese research teams to accelerate development.

The drive toward 100 TB and larger hard‑disk capacities aligns with exploding data‑center, cloud and artificial‑intelligence workloads that demand massive, cost‑effective storage. While solid‑state drives dominate performance‑critical tiers, HDDs remain the most economical solution for bulk archival and cold‑storage layers. HAMR‑enabled drives promise to extend HDD relevance by delivering unprecedented density without prohibitive price increases, ensuring that enterprises can scale storage infrastructure in line with AI model training and large‑scale analytics.

Beyond technical gains, the BoI’s approval signals a strategic push to deepen Thailand’s high‑tech manufacturing ecosystem. Requiring over 60 % local content, the project will spur domestic component suppliers, foster skilled‑labour pipelines, and attract ancillary investment that could swell to 10 billion baht. This infusion of capital and expertise not only reinforces Thailand’s export‑oriented HDD hub but also positions the nation as a critical node in the global supply chain for next‑generation data storage solutions.
