Synology RS1626xs+ Xeon D-1726 4-Bay Rackmount NAS 32GB 16TB 2-Port 10GbE

1U 4-Bay Rackmount NAS

The Synology RS1626xs+ is a 1U rackmount NAS with four drive bays, an Intel Xeon D-1726 processor and 32GB of DDR4 memory. It ships fully assembled with 16TB of Synology Enterprise drives and a dual-port 10GbE adapter installed. The platform targets businesses that need consolidated file storage, virtualization hosting and backup services in a compact form factor.

10GbE networking and expansion limits

Dual RJ-45 10GbE ports provide high-throughput connectivity for demanding workloads, while a dedicated management LAN port handles out-of-band administration. Two USB 3.2 Gen 1 ports allow direct attachment of external storage or peripherals. A PCIe Gen4 x8 slot and dual M.2 NVMe slots remain available for cache or additional network cards, though total raw capacity stays at four bays unless an external expansion unit is added.

Pre-assembled deployment and thermal constraints

The unit arrives tested and populated, so installation reduces to rack mounting, cabling and initial DSM configuration. Operating temperature is rated from 5°C to 35°C with humidity up to 80% RH, so adequate aisle cooling is required. Buyers who need more than four internal drives or who lack a 1U rack space with proper airflow should consider alternative form factors.
