1U 4-Bay Rackmount NAS for Enterprise Workloads
The Synology RS1626xs+ is a 1U rackmount network-attached storage server built around an Intel Xeon D-1726 six-core processor. It ships fully assembled with 64GB of DDR4 ECC memory, 1.6TB of NVMe cache on two 800GB drives, and four 4TB enterprise hard drives totalling 16TB of raw capacity. This configuration targets businesses that need virtualization, backup, surveillance and high-performance file sharing in a single validated appliance.
Dual 10GbE and PCIe Gen4 Expansion Limits
Network connectivity is provided by two built-in 10GbE RJ-45 ports plus a dedicated 1GbE out-of-band management port. A single PCIe Gen4 x8 slot allows one additional network or storage controller, but no further expansion slots exist on the main board. Drive count can grow to 16 bays only by attaching a compatible Synology expansion unit over the rear expansion port.
64GB DDR4 ECC Memory Decides Virtualization Capacity
The installed 64GB of DDR4 ECC RDIMM memory is the fixed upper limit for this unit; the platform does not support further memory upgrades. That ceiling determines how many virtual machines or containers can run concurrently and whether memory-intensive services such as deduplication remain practical. Buyers who need more RAM must select a different model.

Questions about this item
Should I pick the 64 GB RAM option or the 32 GB option for this RS1626xs+?
The unit ships with 64 GB of DDR4 ECC RDIMM installed, which is the maximum supported capacity for the Xeon D-1726 processor.
What does the 1.6 TB NVMe cache actually do for daily workloads?
Two 800 GB enterprise NVMe SSDs accelerate random read and write IOPS, boosting virtualization, database, and heavy multi-user file access performance.
Are the two 10 GbE RJ-45 ports limited to 10 Gbps or can they run faster?
Each port is a 10 GbE RJ-45 interface, so the practical ceiling is 10 Gbps per connection; link aggregation can combine both for higher aggregate throughput.
