The market is projected to reach USD 1.69 billion by 2035, a CAGR of 11.34% from 2025. **How fast is the South Korea Data Center Storage Market growing?** 11.34% a year from 2025 to 2035, DC Market Insights estimates, slower than the 14.12% of 2020-2025 because storage spend per megawatt falls about 3% a year while installed capacity keeps rising. **Which storage type is largest in Korean data centers?** All-flash arrays, at USD 287.75 million or 50% of 2025 spend, rising to 66% by 2035 because AI clusters need flash throughput to keep GPUs busy. **What is the fastest growing segment of Korean data center storage?** Object storage, at 17.99% a year from USD 80.57 million in 2025, because AI checkpoints and the off-site backup copies required after the NIRS fire move to S3-compatible capacity tiers. **Which Korean region leads data center storage spending?** The Capital Region, with USD 402.86 million or 70% of 2025 spend; the Honam Region grows fastest at 24.27% a year as Jeollanam-do campuses add AI capacity. **How did the NIRS Daejeon fire change data center storage in South Korea?** About USD 38 million of extra public storage spend in 2026-2027, DC Market Insights estimates, because the government now requires storage-based disaster recovery for grade A1 to A3 systems by 2027. **How much do Korean data centers spend on storage per megawatt?** About USD 0.36 million per installed megawatt a year in 2025, plus about USD 1.10 million one-off per megawatt of new AI capacity, DC Market Insights estimates; the yearly rate falls to USD 0.27 million by 2035. **Who are the leading data center storage suppliers in South Korea?** Dell Technologies, NetApp and Hewlett Packard Enterprise hold about 44% of external array spend together (DC Market Insights estimate), followed by Pure Storage, IBM, Hitachi Vantara and Huawei. **Why do South Korea Data Center Storage Market estimates differ?** Estimates differ by up to 3 times because broader definitions add memory and SSD output, enterprise storage outside data centers and cloud subscriptions; DC Market Insights counts only storage bought for Korean data center halls, USD 575.51 million in 2025. **How large could the South Korea Data Center Storage Market be by 2035?** Between USD 1.25 billion and USD 1.96 billion, with a base case of USD 1.69 billion, DC Market Insights estimates; grid access for new AI halls decides which case plays out. **How long did it take to restore all 709 government systems after the NIRS Daejeon fire?** About 95 days. The fire on 26 September 2025 took 709 systems offline and burned 96 completely; all 709 were restored on 30 December 2025, according to the Ministry of the Interior and Safety. **What is the recovery target for the most critical government systems after the NIRS fire?** One hour for A1 systems, recovered from a second center. The NIRS recovery briefing of 2 October 2026 also sets storage-based disaster recovery for grade A1 to A3 systems by 2027 and storage backup systems for all three government centers by the end of 2027. **How much storage could NAVER's Sejong AI campus add?** About USD 150 million of storage, a DC Market Insights estimate at today's per-megawatt rate. NAVER, NVIDIA and Brookfield agreed in July 2026 to expand the GAK Sejong AI factory from 55 MW to 200 MW, adding about 145 MW. Sejong grows 15.16% a year to USD 113.27 million by 2035. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 575.51 | USD million | | Revenue CAGR | 11.34 | % | | Market size 2035 | 1,690 | USD million | ## Frequently asked questions ### What is the size of the South Korea Data Center Storage Market in 2026?
