QNAP TS-432PXU-2G Diskless NAS
A diskless four-bay 1U rackmount NAS with an Alpine AL324 quad-core processor, 2 GB DDR4 memory, dual 10GbE SFP+, dual 2.5GbE and PCIe expansion.
Compact rack storage for high-speed sharing and backup
The QNAP TS-432PXU-2G is a diskless four-bay 1U NAS with dual 10GbE SFP+ and dual 2.5GbE connectivity for shared file access, backup and synchronisation. Snapshots, HBS, Boxafe, cloud gateways, PCIe expansion and support for compatible QNAP expansion enclosures give small teams a practical route to protect data and scale beyond the internal bays.
Key features and benefits
Dual 10GbE SFP+
Two built-in 10GbE ports support high-bandwidth file sharing and backup.
Dual 2.5GbE ports
Two RJ45 connections provide flexible multi-gigabit access alongside SFP+.
Backup and synchronisation
HBS supports backup and synchronisation to NAS systems, servers and cloud storage.
Snapshot protection
Snapshots record system status and data to support recovery after deletion or malware incidents.
PCIe expansion
A compatible PCIe card can add network, SSD-caching or wireless connectivity.
Scalable storage
Compatible QNAP TR RAID enclosures and TL JBOD units can extend capacity.
