Synology RS1626xs+ Xeon D-1726 4-Bay Rackmount NAS 32GB 800GB Cache 32TB

4-Bay Rackmount NAS with Xeon D-1726

The Synology RS1626xs+ is a 1U rackmount network-attached storage server built around an Intel Xeon D-1726 processor. It arrives fully assembled with 32GB of DDR4 memory, 800GB of NVMe cache, and four 8TB enterprise drives for 32TB of raw capacity. This configuration targets businesses that need immediate, high-performance file, backup, and virtualization storage without staging components themselves.

Upgrade from slower 1GbE or smaller 2-bay units

Dual 10GbE RJ-45 ports remove the network bottleneck that limits older 1GbE appliances, while the six-core Xeon and ECC memory handle concurrent VMs and heavy multi-user workloads. The jump is worth it when current storage saturates gigabit links, when application latency affects productivity, or when drive bays are exhausted and a 16-drive expansion path is required.

32TB raw with 800GB NVMe read/write cache

The included enterprise drives and dual 400GB NVMe modules accelerate frequent data access and absorb write bursts for databases, virtualization, and collaborative editing. Headroom remains for two additional M.2 slots and a PCIe Gen4 x8 card, while a compatible expansion unit can scale the array to sixteen drives. Environments needing more than 32TB raw or faster than 10GbE networking will outgrow this chassis.
