High-performance 1U rackmount NAS

The Synology RS1619xs+ is a 4-bay 1U rackmount NAS powered by an Intel Xeon D-1527 quad-core processor running at 2.2 GHz with turbo up to 2.7 GHz. It ships with 8 GB of DDR4 ECC UDIMM memory expandable to 64 GB across four slots. The unit supports 3.5-inch and 2.5-inch SATA drives plus M.2 2280 NVMe and SATA SSDs for cache.

Network and expansion limits

Four onboard RJ-45 ports provide 10/100/1000 Mbps connectivity with optional 10 GbE NIC support available. Maximum raw capacity reaches 72 TB using four 3.5-inch drives, and storage can scale to 16 drives by adding Synology RX1217 or RX1217RP expansion units. Sequential read performance exceeds 1,523 MB/s while iSCSI random read IOPS reach 136,558.

Pre-purchase checklist

Verify your rack provides 1U space and operates within 5 °C to 35 °C ambient temperature with 5 % to 95 % relative humidity. Ensure the 100 V to 240 V AC single-phase supply matches your infrastructure and plan for 68.68 W typical access power draw. Confirm the SMB, NFS, iSCSI and VPN protocols required by your workload are supported and select compatible SATA or NVMe drives for the four bays and M.2 slots.

Questions about this item

Should I pick the 8 GB model or upgrade to the 64 GB maximum for my team size?

The unit ships with 8 GB DDR4 ECC UDIMM across four slots; expanding to 64 GB supports heavier virtualization and larger user counts.

What does the 1,523 MB/s sequential read figure mean for daily file access?

That throughput is measured over the four 1 GbE ports with M.2 NVMe cache; real-world SMB transfers will be limited by the 1 GbE network ceiling.

How do the four 1 GbE RJ-45 ports cap actual transfer speeds?

Each port tops out at 1 GbE, so combined throughput cannot exceed the link speed unless an optional 10 GbE NIC is added.
