Synology RackStation RS1619xs+ 4-Bay NAS Enclosure
High‑performance rackmount NAS powered by Intel Xeon D‑1527 (2.2 GHz / 2.7 GHz), 8 GB ECC DDR4 (expandable to 64 GB), 2 M.2 NVMe/SATA SSD cache slots, PCIe expansion, and support for up to 16 drives.
Product Overview
The Synology RackStation RS1619xs+ is a powerful 1U rackmount NAS aimed at SMB and enterprise environments. It features an Intel Xeon D‑1527 quad-core processor (up to 2.7 GHz turbo), 8 GB of ECC DDR4 memory (user-upgradeable to 64 GB across four DIMM slots), and four hot-swappable drive bays. Two built-in M.2 NVMe/SATA SSD slots support caching for accelerated I/O. With four Gigabit LAN ports supporting link aggregation and failover, a PCIe Gen3 x8 slot for optional 10/25 GbE or SSD cache cards, and compatibility with the RX1217/RX1217RP expansion unit (up to 16 total bays), it delivers reliable, scalable storage.

FAQs
Q1: What is the maximum supported RAM?
Supports up to 64 GB ECC DDR4 using four UDIMM slots (one 8 GB module pre-installed).
Q2: Does it support SHR?
No—Synology enterprise models like RS1619xs+ do not include Synology Hybrid RAID. However, RAID volumes can be migrated (e.g., RAID 1 to RAID 5) without data loss.
Q3: Can NAS hosts use the built-in NVMe slots for storage volumes?
No—those slots are strictly for SSD caching to accelerate I/O performance; they cannot host storage volumes.
Q4: Is fan noise high during operation?
Yes—the stock dual fans can be noticeably loud (≈39 dB(A)), particularly in quiet environments. Users have reported replacing them with quieter aftermarket fans, though warranty implications should be considered.
Q5: How many cameras can it support?
Supports up to 75 IP cameras (two camera licenses included by default), making it suitable for robust surveillance deployments.
Q6: Is it capable of virtualization and heavy workloads?
Yes—capable of sustaining high throughput (e.g. ~1.5 GB/s sequential read, ~160K iSCSI IOPS) and supporting Virtual Machine Manager, Active Backup, and iSCSI applications.
