Synology RS1626xs+ Xeon D-1726 4-Bay Rackmount NAS 16GB 96TB 25GbE

1U 4-Bay Xeon NAS with 25GbE

The Synology RS1626xs+ is a 1U rackmount NAS built around an Intel Xeon D-1726 processor with 16GB of DDR4 memory. It ships fully assembled with four 24TB enterprise drives for 96TB of raw capacity. The system targets organisations that need high-throughput file, backup and virtualization services in a compact form factor.

Network limits of 10GbE and 25GbE

Dual onboard 10GbE RJ-45 ports handle mainstream server links, while the included PCIe card adds two 25GbE SFP28 ports for faster aggregation. Throughput above 10GbE requires compatible switches, transceivers and cabling; the 1GbE management port remains separate for out-of-band access. Real-world speed depends on the slowest link in the path.

Upgrade from 1GbE or smaller bays

Teams moving from 1GbE NAS appliances gain an order of magnitude more bandwidth for concurrent VMs and large datasets. The jump is worthwhile when current storage saturates 1GbE uplinks or when drive bays limit capacity growth. Buyers who need more than four internal bays or who require GPU-accelerated workloads should look elsewhere.
