What this subsidiary actually does
Seagate Thailand manufactures HDDs, heads, media, precision mechanical components across two major plant complexes (Teparuk, Korat). Customer-product mix: enterprise mass-capacity HDD (nearline, hyperscaler, archival), client HDD (consumer PC, external storage), specialty HDD (video surveillance, NAS). HAMR (heat-assisted magnetic recording) next-gen density technology, Mozaic series are the medium-term product roadmap centrepiece.[]
Strategic position: Seagate, Western Digital form the global HDD duopoly (plus Toshiba at smaller share). Both operate major Thai manufacturing; competitive position tracks parent-company strategy. Enterprise mass-capacity growth offsets client HDD decline; HAMR technology is the bet to extend HDD competitiveness vs flash.[, ]
Business segments
Enterprise HDD
Nearline, hyperscaler, archival
Enterprise mass-capacity HDD for cloud hyperscalers (AWS, Azure, Google), nearline and archival storage. Highest-margin segment; compound annual volume growth driven by AI data-storage demand.
Client HDD
Consumer, PC, external storage
Consumer desktop, laptop, and external storage HDD. Declining segment due to flash substitution; managed for cash flow. Korat plants supply client HDD alongside enterprise products.
Specialty HDD
Surveillance, NAS applications
Surveillance-optimised and NAS (network-attached storage) HDD for security systems and home-office storage. Niche but resilient segment with higher ASP than commodity client HDD.
HAMR technology
Mozaic series — next-gen density
Heat-assisted magnetic recording (HAMR) is Seagate's technology bet for extending HDD areal density. Mozaic product line targets 50TB-plus per drive. Thai plants critical for HAMR volume production ramp.

Key drivers 2025-2026
AI storage demand
Hyperscaler capacity build
AI model training and inference data storage is driving enterprise mass-capacity HDD demand. Each AI training cluster requires petabytes of storage; Seagate enterprise HDD is a direct beneficiary.
HAMR ramp
Mozaic volume production
HAMR technology production ramp at Thai plants is the key FY2025-2026 execution milestone. Yield improvements and cost reduction on HAMR determine Seagate's competitive density lead over WDC.
Supply chain resilience
Post-2011 flood diversification
Post-2011 Thailand flood recovery investment strengthened Thai plant resilience. BOI investment incentives and deep supplier ecosystem keep Thailand as preferred HDD manufacturing base.
