Start compact, add M.2 cache and scale storage to 16 drive bays
The RS1619xs+ combines a compact 1U chassis with enterprise-oriented memory, M.2 and PCIe expansion. It is designed for growing businesses that need reliable file services, backup, collaboration and virtualisation storage without starting with a large multi-bay enclosure.
Four hot-swappable bays
Use compatible SATA HDDs or SSDs for primary storage while retaining a compact 1U footprint.
Two built-in M.2 slots
Install compatible M.2 2280 NVMe or SATA SSDs for supported cache configurations without using front bays.
Scale to 16 bays
One RX1217 expansion unit can increase the verified storage-bay count from four to sixteen.
Xeon and ECC memory
The Intel Xeon D-1527 and 8 GB ECC memory provide a business-focused processing platform.
Full-link PCIe slot
A Gen3 x8 slot with x8 link supports compatible high-speed networking expansion.
Redundant power
Dual power supplies help maintain service through a single PSU or cord interruption.
Who is the Synology RS1619xs+ best for?
A strong choice for
- Growing business file and backup storage
- Compact 1U deployments
- M.2 SSD cache configurations
- Organisations scaling from four to sixteen bays
- Deployments requiring redundant power
Consider another model if you need
- More than four internal front-access bays
- Built-in 10GbE without a PCIe card
- A current-generation replacement model
- A desktop enclosure rather than rackmount storage
