The TS-h973AX has four 2.5-inch SSD slots - with slots 1 & 2 supporting both high-performance U.2 NVMe PCIe Gen 3 x4 SSDs or economical SATA 6Gb/s SSDs. For tackling latency-sensitive applications, you can take advantage of U.2 NVMe PCIe Gen 3 x4 SSDs that supply up to 32Gb/s bandwidth to attain optimized performance and efficiency. You can also use QNAP’s QDA adapter to replace U.2 NVMe SSDs with cost-efficient M.2 NVMe SSDs to maintain high-level performance while saving more costs.
Note: U.2 SSDs cannot be installed in the SATA drive bays (including the 3.5-inch bays and SSD Slots 3 & 4).
Coupled with QNAP’s SSD-aware features, the TS-h973AX maximizes performance with high cost-effectiveness.
| SSD cache acceleration | Write Coalescing | Pool Over-provisioning |
|---|---|---|
| Increases IOPS performance and reduces latency for storage volumes - perfect for IOPS-demanding applications including virtualization and databases. | Transforms all random writes to sequential writes along with reduced I/O, effectively increasing SSD write performance. | Flexibly reserves a dedicated space in an SSD storage pool to allow new data to be written into a complete block even if the pool is almost full, thus improving the performance of fragmented pools. |
Install one or more QDA adapter in the TS-h973AX (Slot 1 and Slot 2) to maximize PCIe bandwidth utilization in a cost-effective way by using M.2 PCIe NVMe SSD instead of the U.2 SSD for optimizing data-intensive applications. It can also boost IOPS performance when configuring SSD caching. Users can monitor drive health and manage SSD usage from the QTS Storage & Snapshots Manager. The M.2 SSD installed in the QDA adapter is hot swappable.

QuTS hero combines the app-based QTS with the 128-bit ZFS file system to provide flexible storage management, comprehensive data protection, and optimized performance to tackle the complexity and performance demands of modern IT. From storage management, virtualization, to collaborative media workflows, QuTS hero streamlines your business-critical tasks.
QuTS hero’s self-healing ensures data integrity and reliability. Write Once, Read Many (WORM) is also supported.
Inline data deduplication, compression, and compaction reduce file size to conserve storage capacity and optimize performance.
Main memory read cache (L1 ARC), SSD second-level read cache (L2 ARC), and ZFS Intent Log (ZIL) for synchronous transactions with power fail protection are simultaneously supported to boost performance and security.
Multiple RAID levels allow flexible capacity utilization. RAID Triple Parity and Triple Mirror deliver higher levels of data protection.
RAID-level SSD lifespan is automatically and regularly detected to prevent simultaneous SSD failure, improving your data protection and system reliability.
Apps for backup/sync, virtual machines/containers, content management, productivity, and more features can be used to expand the application potential of the TS-h973AX.
QuTS hero supports advanced block-based data reduction technologies (including inline data deduplication*, compression, and compaction) to reduce file sizes, conserve storage capacity, and optimize performance. For example, if 20 virtual machines on a NAS are replicated using the same template, then storage space requirements for all 20 virtual machines can be reduced by up to 95%. Whether acting as primary or backup storage, the TS-h973AX optimizes storage utilization to provide a reliable storage cornerstone in the Big Data era.
*Note: Inline data deduplication requires at least 16 GB memory. The TS-h973AX-32G model features 32 GB memory that allows you to attain complete dedup function.
Real-time SnapSync ensures that both the primary and secondary NAS maintain identical data. When data is written to the source, it is immediately written to the destination. If the primary NAS goes offline, IT staff can simply adjust the privilege settings of the secondary NAS to ensure continuous operations. SnapSync provides the strongest support for nonstop business operations and helps users to reduce the risk of data loss.
Note: SnapSync will be available from QuTS hero h4.5.2.
The TS-h973AX also supports snapshots and remote backup to help organizations accomplish routine backup tasks cost-effectively and efficiently.
Attain peace of mind with near-limitless, instant snapshots. Copy-on-write technology makes snapshot creation almost instantaneous without affecting ongoing data writing. Snapshot Replica replicates snapshot files to the backup NAS, simplifying data protection with version control.
HBS centralizes backup, restoration, and synchronization for easily transferring data in the TS-h973AX to another QNAP NAS, remote server, or cloud storage space. HBS supports QuDedup technology that eliminates redundant data at the source and makes multi-version backup faster.
You can count on Virtualization Station and Container Station for comprehensive virtualization support. Coupled with the Network & Virtual Switch app that boosts interoperability between virtual machines, containers, QNAP NAS, and other physical devices on the network, you can flexibly allocate physical and virtual network resources to simplify network deployment.
Run multiple Windows®, Linux®, UNIX®, and Android™ virtual machines and access them via a web browser or Virtual Network Computing (VNC). Businesses can run virtualized server applications on a single NAS without the need for additional physical servers.
