Enterprise 12-Bay NAS with 25GbE
The Synology RS3626xs is a 2U rackmount network-attached storage server pre-loaded with 192 TB of raw capacity across twelve 16 TB enterprise-class SATA drives. A six-core Intel Xeon D-1726 processor and 32 GB of DDR4 ECC memory drive file services, virtualization and backup workloads for businesses that need high throughput in a compact form factor. Dual redundant power supplies protect uptime against a single supply failure.
Upgrade from 10GbE or single-port 25GbE
The included two-port 25GbE SFP28 adapter replaces slower 10GbE links or single-port 25GbE cards, doubling available bandwidth for hypervisor storage, video editing shares or multi-site replication. The jump is worth it when sustained sequential workloads regularly saturate 10 Gb/s links or when failover across two physical ports is required for service-level agreements. Two PCIe Gen 4 x8 slots remain open for future caching or fibre-channel expansion.
Limits of 25GbE SFP28 and 12-bay SATA
Throughput tops out at 25 Gb/s per port, so aggregate bandwidth cannot exceed 50 Gb/s without additional adapters. Twelve 3.5-inch bays cap raw capacity at the installed 192 TB unless larger SATA drives become available. Memory maxes at 48 GB, limiting concurrent virtual machines or heavy deduplication tasks. Operating temperature range stops at 35 °C, requiring controlled server-room cooling.

Questions about this item
What rack depth and weight clearance does the 88 mm × 482 mm × 724 mm, 14.5 kg chassis require?
The 2U unit is 724 mm deep and weighs 14.5 kg; verify your rack rails support at least that depth and load before mounting.
Which expansion slot do I use for the included 2-port 25GbE SFP28 adapter, and what common step is missed?
Install the adapter in one of the two PCIe Gen 4 x8 slots, then attach the SFP28 transceivers and cables — many forget to seat the transceivers fully so the link never comes up.
When will the twelve 16 TB SATA drives need replacement, and what is the memory upgrade path?
Plan drive replacement after the rated workload or warranty period; memory can be expanded from 32 GB to 48 GB using compatible DDR4 ECC modules.
