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.

Questions about this item
Should I choose the 96 TB configuration or add drives later?
The unit ships with four 24 TB enterprise drives filling all four bays for 96 TB total; adding more drives requires a compatible Synology expansion unit.
What does the Xeon D-1726 and 16 GB DDR4 ECC mean for real workloads?
The 6-core Xeon D-1726 with 16 GB DDR4 ECC RDIMM handles virtualization, backup, surveillance and heavy file sharing; memory can be expanded to 64 GB.
How fast are the 25 GbE SFP28 ports in practice?
Dual SFP28 ports on the included PCIe Gen4 x8 adapter provide 25 GbE connectivity; actual throughput depends on switch, cabling and workload.
