Enterprise Rackmount NAS
The Synology RS1626xs+ is a 1U rackmount NAS built around an Intel Xeon D-1726 six-core processor with 16GB of DDR4 ECC memory. It ships fully assembled with four 20TB enterprise drives providing 80TB of raw capacity and two 1.6TB NVMe cache modules totalling 3.2TB. The platform targets businesses that need high-throughput file sharing, virtualization hosting, backup consolidation, or surveillance storage in a compact four-bay form factor.
Thermals Noise Power
The chassis operates within a 5°C to 35°C ambient range and draws power from dual 100-240 VAC supplies at 50/60Hz. Two integrated 10GbE RJ-45 ports and a dedicated 1GbE management link handle network traffic without additional cards. A PCIe Gen4 x8 slot remains available for further I/O expansion while the system runs its standard workloads.
Upgrade Path Limits
The four-bay design caps internal drive count at four units, so organisations planning more than 80TB of raw storage must add a compatible Synology expansion unit to reach the 16-drive maximum. Memory can grow to 64GB for heavier virtualization, but the single PCIe slot and fixed bay layout limit further internal upgrades. Buyers who need more than four drives today should evaluate larger chassis options.

Questions about this item
How do I install the RS1626xs+ into a standard 1U rack and which step is often missed?
Mount the 44 mm high unit using the included accessory pack, connect both C13 to C14 power cords for redundancy, link the two 10GbE RJ-45 ports and the dedicated out-of-band management LAN port, then power on. The step most often missed is cabling the separate management port before first boot.
What maintenance or replacement will the RS1626xs+ need over time?
The four 20 TB enterprise drives and two 1.6 TB NVMe cache modules are field-replaceable; plan to swap any drive that SMART flags as degraded and replace cache SSDs once their write-endurance rating is reached. Memory can be expanded later with DDR4 ECC RDIMMs up to 64 GB total.
What is the first limit reached under sustained heavy workloads on the RS1626xs+?
The operating temperature ceiling of 35 °C is typically the first constraint; continuous high I/O across the 10GbE links and NVMe cache can push the 1U chassis to that limit, triggering fan-speed increases and possible throttling if airflow is insufficient.
