The Synology RackStation RS2416RP+ is a discontinued 12-bay business NAS from 2015, not a current-generation purchase. Its standout feature is redundant power supplies; Synology still lists DSM updates as Full but technical support as Limited. It may make sense as a used expansion or replacement for an existing Synology setup, but buyers should verify software support, hardware condition, drive compatibility and seller return terms before relying on it.
What is the Synology RS2416RP+?
Synology announced the RS2416+ and RS2416RP+ on September 3, 2015. The RS2416RP+ is a rackmount NAS with twelve hot-swappable SATA drive bays, aimed at business storage rather than a typical home setup. Its defining distinction is a pair of redundant power supplies. Synology also described snapshots, data-integrity features, link aggregation and failover, SSD cache support, and expansion to 24 drives as product capabilities; those are manufacturer-described features, not independent test results.

RS2416RP+ specifications
| Specification | RS2416RP+ |
|---|---|
| Processor | Intel Atom C2538, quad-core, 2.4 GHz (Synology datasheet) |
| Memory | 2 GB DDR3 standard; expandable to 6 GB (Synology datasheet) |
| Drive bays | 12 hot-swappable SATA II/III bays (Synology datasheet) |
| Network | Four Gigabit Ethernet ports (Synology datasheet) |
| Maximum internal raw capacity | 96 TB, calculated by Synology as 12 × 8 TB; this is a historical datasheet configuration, not confirmation of current drive compatibility |
| Ports | Two USB 3.0, two USB 2.0 and one expansion port (Synology datasheet) |
| Filesystems | Btrfs and ext4 internally (Synology datasheet) |
| Power | Redundant power supplies; the standard RS2416+ does not have this RP+ distinction (Synology launch announcement) |
The official datasheet lists AES-NI hardware encryption and storage modes including SHR, Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10. The right mode depends on the balance between usable capacity, fault tolerance and performance: for example, RAID 0 prioritizes capacity and speed but provides no drive-failure redundancy, while RAID 6 can tolerate two drive failures at the cost of capacity. RAID is not a backup; keep separate copies of important data.

What is the difference between RS2416+ and RS2416RP+?
The documented distinction is the redundant power supply configuration in the RS2416RP+. Synology’s announcement says: “In addition to the standard four Ethernet ports with failover and Link Aggregation support, the RS2416RP+ variant includes redundant power supply units in order to maximize service uptime and business continuity.” The four Ethernet ports and the stated link aggregation and failover support are common platform features; the RP+ adds power redundancy. A redundant PSU can reduce the risk of an outage from one failed supply, but it does not protect against every hardware failure or replace a backup and recovery plan.
Is the Synology RS2416RP+ still worth buying?
It is a conditional used-market choice, most defensible when you need a rackmount 12-bay system that fits an existing Synology environment or need a like-for-like replacement. Synology lists the unit as discontinued, with DSM Update marked Full and Technical Support marked Limited. “Limited” means basic consultation after the operating system reaches its End of Extended Life phase; repair or replacement may depend on available parts and may involve a fee. The Full update label is not a promise of indefinitely continued DSM releases. Synology product status

There are no independently established throughput benchmarks, noise measurements, thermal tests or controlled reliability results for this review. The specified Atom C2538 alone does not establish how well the NAS will perform on a particular workload. Before buying, compare the actual price and remaining support lifecycle against current alternatives, and check that its processor, 6 GB memory ceiling, Gigabit networking, expansion options and supported software suit your needs. Country-specific used stock and prices vary.
Used-unit checks
- Review system logs and drive-health information, and confirm the included drives are suitable for your intended use.
- Verify that both power supplies and the fans are present and working.
- Confirm the seller’s return window and what it covers.
- Test the NAS under your own workload before making it the primary home for important data.
- Check Synology’s current drive-compatibility information and parts availability before purchasing disks or planning repairs; the old 96 TB figure does not confirm present-day drive support.
Does the RS2416RP+ support DSM 7?
Synology’s DSM 7.2 release notes list the RS2416RP+ among models that require manual installation. Owners should follow the model-specific release notes and download instructions rather than assume every update will appear as a normal in-product notification. Confirm the latest supported DSM release in Synology’s Download Center before planning an upgrade. DSM release notes for RS2416RP+

Can the RS2416RP+ use an RX1217 expansion unit?
Yes. Synology lists the RX1217 as compatible with the RS2416RP+. The company’s expansion guidance recommends keeping volumes within one device—either the NAS or the expansion unit—rather than spanning a volume across both, for performance reasons.

What to compare before choosing a used 12-bay NAS
- Lifecycle: Check the remaining operating-system and support window, not just whether the unit boots.
- Workload: Match the processor and memory ceiling to the services you will run, and verify current package support.
- Storage: Calculate usable capacity and fault tolerance for your chosen drives and RAID or SHR configuration.
- Connectivity: Confirm four Gigabit ports meet your network needs; do not assume newer or faster interfaces.
- Expansion and resilience: Account for RX1217 compatibility and the RP+ redundant power supplies.
- Ownership costs: Consider qualified-drive availability, spare parts, power use and noise, as well as the purchase price.
