SSD cache acceleration
The TS-431XeU supports SSD caching to greatly boost the IOPS performance of storage volumes to increase operational efficiency. It is perfect for improving the overall workflow of IOPS-demanding applications and allows the best of both cost and performance by combining SSDs with HDDs.

Reduce the impact of ransomware or system failure with Snapshots
The TS-431XeU supports snapshots, which can record the system status and data at any single moment*. If the system unexpectedly fails or is infected with ransomware, you can instantly restore files from a snapshot. The intuitive snapshot tool in the QTS Storage Manager can be used to take snapshots of your data, and restore data from snapshots if necessary. Always take regular snapshots to ensure the safety of your files and data.

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. The system can be recovered by reinserting the wrongly-removed hard drives so the data can still be accessible. The TS-431XeU delivers high reliability and efficiency with support for multiple port-trunking modes including fail-over support.

VJBOD: Maximize storage utilization across multiple QNAP NAS
Besides using expansion enclosures, there is an additional option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is network-based JBOD, allowing you to expand the storage of a QNAP NAS with multiple QNAP NAS units. The TS-431XeU offers great potential for economically expanding the storage of other QNAP NAS with VJBOD, and to create virtual storage pools and volumes on virtual disks for operating NAS services.
