4-Bay Rackmount NAS with Xeon D-1726

The Synology RS1626xs+ is a 1U rackmount NAS powered by an Intel Xeon D-1726 processor and 32GB of DDR4 memory. It arrives fully assembled with four 20TB Synology Enterprise drives for a total of 80TB raw capacity. Dual 10GbE RJ-45 ports and a dedicated management LAN provide high-speed network connectivity. The unit includes two USB 3.2 Gen 1 ports and operates on 100-240 VAC power.

Suited for virtualisation and heavy file workloads

This system targets businesses that need strong multi-threaded performance for virtual machines, intensive file sharing, or backup repositories. The Xeon CPU and ECC memory combination supports demanding applications reliably. Organisations requiring more than four drive bays without adding an expansion unit should consider alternative platforms. Buyers without rack infrastructure or 10GbE networking will not utilise the full feature set.

Sustained throughput with ECC memory stability

Under continuous load the Xeon D-1726 maintains consistent processing power for encryption, deduplication, and snapshot operations. DDR4 ECC memory corrects single-bit errors to protect data integrity during long-running tasks. Dual 10GbE links sustain high throughput for replicated backups or virtual machine migration. The 5°C to 35°C operating range ensures stable performance in standard server-room conditions.

Questions about this item

What drives must I already have to populate the four bays?

The unit ships with four 20 TB Synology Enterprise NAS drives already installed, providing 80 TB total capacity.

Can I keep using my existing 1 GbE network while adding the 10 GbE ports?

Yes, the RS1626xs+ includes two 10 GbE RJ-45 LAN ports plus a dedicated 1 GbE out-of-band management port that can run alongside older switches.

How do I verify the 32 GB of DDR4 ECC memory is recognised after first boot?

Log into DSM, open Resource Monitor, and confirm the Memory section reports 32 GB installed.
