Demonstrates Corporate Trust in Hitachi Vantara’s Mission-Critical Data Infrastructure
SANTA CLARA, Calif., May 21, 2026 – Hitachi Vantara, Ltd. (hereinafter "Hitachi Vantara"), a group company of Hitachi, Ltd. (hereinafter "Hitachi"), announced today that it has ranked first in the IDC Worldwide Quarterly Enterprise Storage Systems Tracker Q4 2025. Hitachi Vantara secured the top position in the enterprise external block storage systems market in Japan for the full year 2025 (January–December 2025) based on vendor revenue.
The company has supported systems that cannot afford to stop—such as those in finance, electric power, and railways—for over 50 years, protecting customers’ most valuable asset: their data. The company believes that its long-cultivated expertise in high-quality manufacturing, comprehensive maintenance support capability, and advanced security features that safeguard data from ransomware have enabled it to consistently meet its customers’ stringent reliability requirements, which in turn led to the recent achievement of having the number one market share. The company will continue to provide high reliability data platforms for mission-critical systems that support social infrastructure, and also offer it as the data foundation for "Hitachi iQ," an AI infrastructure solution which was expanded in March 2026*1 to accelerate the production deployment of agentic AI, and “HMAX by Hitachi,” a suite of next-generation solutions that apply AI to address complex challenges in social infrastructure across a wide range of sectors, including mobility, energy, and industrial systems.
