The NVMe all-flash TS-h2490FU is designed for providing extreme performance with high cost-efficiency. Featuring 24 U.2 NVMe Gen 3 x4 SSD bays, the TS-h2490FU delivers up to 661K / 245K random read/write IOPS with ultra-low latency. The ZFS-based QuTS hero operating system supports inline data deduplication and compression for reducing I/O and SSD storage consumption, which significantly extends SSD lifespan with a higher price-performance ratio for all-flash storage arrays. Coupled with near-unlimited snapshots, real-time SnapSync, and petabyte-scale storage expansion capabilities, the TS-h2490FU is ideal for I/O-intensive and latency-sensitive applications, and eliminates productivity bottlenecks in modern data centers, virtualization, and mission-critical backup/restore tasks.
