Ready-to-deploy 4-bay rackmount NAS

The Synology RS1626xs+ arrives fully assembled with an Intel Xeon D-1726 processor, 16GB DDR4 ECC memory, 1.6TB NVMe cache and four 20TB enterprise drives delivering 80TB raw capacity. It targets businesses that need immediate virtualization, backup and file-sharing performance without manual integration.

Pre-installation checklist

Verify the rack provides a 1U slot measuring at least 44mm high, 481.9mm wide and 668.5mm deep, and that the 9.5kg unit is within the shelf rating. Confirm two C13 inlets can reach redundant UPS circuits operating at 100-240VAC 50/60Hz and that ambient temperature stays between 5°C and 35°C.

Daily operation cues

Dual 10GbE RJ-45 ports and a dedicated management LAN give separate data and control paths. Two USB 3.2 Gen 1 ports allow quick peripheral attachment, while the front cover secures the hot-swap drive bays. Web-based DSM management runs headless once the initial network configuration is applied.

Questions about this item

Does the RS1626xs+ ship with the 4 x 20 TB drives, 1.6 TB cache and 16 GB RAM already installed, or must I add them myself?

The unit arrives fully assembled and tested with four 20 TB Synology Enterprise NAS drives, two 800 GB Synology Enterprise cache modules and 16 GB DDR4 ECC RDIMM memory pre-installed.

Should I select the base 16 GB memory or upgrade toward the 64 GB maximum for virtualization workloads?

The installed 16 GB DDR4 ECC RDIMM suits general file sharing and backup; workloads running multiple virtual machines or heavy databases benefit from adding modules up to the 64 GB limit.

What throughput can I expect from the dual 10GbE RJ-45 ports when the cache and drives are active in a production RAID?

Dual 10GbE links provide up to 10 Gbps each for sequential reads and writes, with the 1.6 TB NVMe cache accelerating random I/O for databases and virtual-machine storage.
