4-bay Xeon rackmount NAS
The Synology RS1626xs+ is a 1U rackmount network-attached storage server built around an Intel Xeon D-1726 processor with 16GB of DDR4 ECC memory. It arrives fully assembled and tested with four 16TB Synology enterprise drives installed, providing 64TB of raw capacity out of the box. Dual 10GbE RJ-45 ports and a dedicated management LAN port are included via a PCIe adapter card.
Suits virtualisation and backup workloads
This platform targets organisations that run virtual machines, host large file shares, or operate backup and surveillance repositories where ECC memory and 10GbE throughput matter. The four-bay chassis limits internal drive count unless a compatible expansion unit is added, so environments that need more than four drives internally should evaluate larger chassis options. Buyers who do not require ECC memory or 10GbE connectivity may find simpler systems more cost-effective.
16GB DDR4 ECC memory installed
The unit ships with 16GB of DDR4 ECC RDIMM memory, expandable to 64GB using compatible modules. This capacity ceiling determines how many concurrent virtual machines or cached workloads the system can sustain without paging. Confirm the memory limit matches your application sizing before purchase.

Questions about this item
How often should the four 16TB Synology Enterprise NAS drives be checked or replaced?
Synology Enterprise NAS drives are rated for continuous operation; monitor SMART data in DSM and replace any drive that reports reallocated sectors or shows consistent latency increases.
Which component reaches its limit first when the Xeon D-1726 runs at full load for hours?
The 16GB DDR4 ECC RDIMM memory ceiling is reached before the 6-core Xeon D-1726 throttles, limiting concurrent VMs or heavy caching workloads.
How much heat and fan noise does the 1U chassis produce during all-day operation?
Operating temperature range is 5°C to 35°C; dual redundant fans spin faster as intake air approaches the upper limit, increasing audible airflow in a 1U rack.
