Smaller footprint for bigger opportunities

Compared to a traditional 4-bay rackmount NAS, the compact TS-451DeU has a depth of only 11.57 inches (295 mm). This makes the TS-451DeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-451DeU is space-saving for flexible deployment and is especially suitable for multiple locations and applications including offices, audiovisual rooms, and security surveillance recording.

Note: Users can purchase the optional RAIL-B02 rail kit to deploy the TS-451DeU in a 19-inch rack following the ANSI/EIA-RS-310-D standard.

SSD caching and auto-tiering optimize application performance

Besides using 2.5-inch SSDs for cache acceleration, the TS-451DeU features two M.2 SSD slots that enable you to install SATA 6Gb/s M.2 SSDs with 2280 form factors (sold separately). Coupled with QNAP’s SSD-aware features, the TS-451DeU maximizes performance with high cost-effectiveness.

SSD over-provisioning
SSD cache accelerationQtier for auto-tiering
Add additional SSD over-provisioning (1% ~60%) to prevent write amplification issues and improve SSD random write speeds and endurance. You can potentially attain enterprise-grade SSD performance levels from consumer-level SSDs!Enables SSD caching for increasing IOPS performance and reducing latency for storage volumes. This feature is perfect for IOPS-demanding applications including databases and virtualization. The TS-451DeU also supports write-only cache to boost write-intensive applications.Qtier technology drives auto-tiered storage with continuous data optimization across high-performance SSDs and high-capacity HDDs based on access frequency. I/O-Aware Qtier can reserve a cache-like space in the SSD tiered to handle burst I/O in real time.
