Synology RS1626xs+ Xeon D-1726 4-Bay Rackmount NAS 64GB 3.2TB Cache 64TB Drives

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 processor. It ships fully assembled with 64GB of DDR4 memory, 3.2TB of NVMe cache across two 1.6TB drives, and four 16TB enterprise hard drives providing 64TB of raw capacity. The unit targets organisations that need high-throughput file services, virtualization hosting, or backup repositories in a compact form factor.

Suited for Virtualization and Multi-User File Access

This configuration suits IT teams running virtual machines, container workloads, or heavy multi-user file sharing where the Xeon six-core CPU and large memory pool reduce latency. The dual 10GbE RJ-45 ports and dedicated management LAN simplify network segmentation. Buyers who only need basic file storage for a small workgroup, or who require more than four drive bays without adding an expansion unit, should evaluate other platforms.

Slide-In Drive Trays and Web-Based Setup

Installation uses tool-less drive trays that slide into the front bays; the NVMe cache modules occupy internal M.2 slots accessible after removing the top cover. Initial configuration runs through the web-based DiskStation Manager interface, which handles RAID creation, volume setup, and service deployment. Common issues include forgetting to initialize the cache pool before creating volumes, and overlooking the separate management port when planning network cabling.
