QSAN XN4226D Excels in StorageReview Tests
Lab validation confirms 21+ GB/s throughput and microsecond latency for AI and media workloads
Pittsburgh, PA - October 14, 2025 - The QSAN XN4226D all-NVMe unified storage system has demonstrated exceptional performance in comprehensive testing by StorageReview. The recent evaluation, published October 13, 2025, reveals the system's ability to handle demanding workloads while maintaining consistent operation.
Testing showed the system achieving 21.21 GB/s on large sequential reads and 11.14 GB/s on large sequential writes. The storage array maintained fast response times across various workload types, proving suitable for AI applications, media production, and virtual machine environments.
The XN4226D lands exactly where many IT teams need it to be, it's a unified system that supports both modern and legacy protocols without requiring architectural changes.
said Andrew Waag, who led the testing.
The evaluation covered multiple performance aspects, showing TCP connections excelled for large sequential reads while RDMA delivered better write performance and lower latency under heavy loads. This flexibility allows organizations to match connection types to specific application needs.
Key features that stood out in testing include:
- Dual active controllers ensuring continuous operation
- Support for both block and file storage in one platform
- Data protection through snapshots and replication
- Multiple connectivity options including high-speed networking
- Simple expansion capabilities for growing storage needs
The QSM 4 management system received positive marks for its straightforward interface, enabling efficient system management through both web interface and automation tools.
Available through JetStor and QSAN's partner network, the XN4226D provides enterprise-level storage performance for organizations with demanding data requirements.
