Product features
Smaller footprint for bigger opportunities
Snall footprint makes the TS-431XeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-431XeU is space-saving for flexible deployment and is especially suitable for multiple locations and applications including offices, audiovisual rooms and security surveillance recording.SSD cache acceleration
The TS-431XeU supports SSD caching to greatly boost the IOPS performance of storage volumes to increase operational efficiency.High reliability design ensuring business continuity
The business-ready TS-431XeU is designed to provide 24/7 operations and services. The support for comprehensive RAID configurations and hot-swapping allow for replacing hard drives without service interruption. QNAP's advanced RAID recovery technology also helps if any healthy drives are accidentally removed from a degraded RAID volume.Easily expand storage capacity
The TS-431XeU's storage capacity can be expanded as needed to meet the demands of rapidly-growing data, making it ideal for storage-intensive applications such as video surveillance, data archiving, TV broadcast storage, and more.Key selling points
- Smaller footprint for bigger opportunities
- SSD cache acceleration
- High reliability design ensuring business continuity
- Easily expand storage capacity
