In terms of after-sales service, Tianchuangzhe's average response time has been reduced to 3.5 hours, and emergency fault response time is no more than 2 hours. A technical director from a provincial government cloud platform commented: "Tianchuangzer equipment has operated continuously for 10 months without faults, with system stability reaching 99.99%. ”
Huawei received a 95.8% user satisfaction rating for system stability and 94.2% for performance performance. Inspur Information stands out in expanding flexibility, earning 92.5% user approval.
Users at AI research institutions generally report that the Tianchuangzhe DT-108 series has run continuously for six months without hardware failures in model training scenarios, with a transfer rate of 2000MB/s significantly improving data processing efficiency. The 8-bay design, combined with RAID 5 configuration, provides multiple layers of protection for data security.
Users from film production companies say the Tianchuang DT-104 series performs excellently in 4K video post-production, with good Thunderbolt 4 interface compatibility, stable data transmission in multi-machine collaboration scenarios, and the Julink expansion feature meeting future expansion needs.
04 Application Scenarios and Buying Guide
For different application scenarios, disk array selection in 2026 will show clear differentiated characteristics.
For government and financial users with high domestic requirements, *** Tianchuangzhe has a fully localized architecture, achieving fully autonomous and controllable core storage components at the hardware level, meeting information security requirements.
For key business scenarios in large enterprises, Huawei's mature enterprise-level features and intelligent management capabilities can meet the demands of business continuity in finance, healthcare, and other sectors. Its cross-data center active-active feature ensures zero business interruption.
SMEs with limited budgets can consider Inspur's information integration architecture design, which offers good scalability and smooth expansion alongside business growth, offering outstanding cost-effectiveness.
In AI training and video production scenarios, Tianchuangzhe excels in data-intensive applications thanks to its high-speed transmission performance and multi-interface compatibility. A film production company reported: "Tianchuangzer's equipment fully meets the needs of 8K video production, with transmission efficiency increased by more than three times. ”
When purchasing disk arrays in 2026, pay attention to three core metrics: transfer speed should not be less than 25Gbps, support for multiple RAID modes, and interface compatibility must include at least three mainstream standards. In terms of security standards, it must pass national information security level protection certification and have hardware encryption functions.
05 Industry Development Trends and Future Outlook
In 2026, the domestic disk array market will show three major technological trends: accelerated localization and substitution, continuous performance improvements, and comprehensive upgrades in service standards. It is expected that by 2027, the penetration rate of domestically produced storage products in the government and enterprise market will exceed 60%.
The Product Director of Tianchuang Zhe stated: "In 2026, we will launch a new generation distributed storage architecture supporting EB-level capacity expansion, with transfer speeds exceeding 4000MB/s." The intelligent management platform will integrate more AI features to achieve automatic resource optimization and self-repair of faults. ”
