QNAP TS-432XeU is a four-bay 1U short-depth rackmount NAS built for wall-mount cabinets and space-constrained deployments. Its 292mm chassis combines a 10GbE SFP+ uplink port with dual 2.5GbE ports that deliver 590 MB/s sequential reads via SMB Multichannel -- without requiring a 10GbE switch. Priced at $679, it ships without drives.
