Synology RS822RP+ 4-Bay RackStation NAS (Diskless)

Name: Synology RS822RP+ 4-Bay RackStation NAS (Diskless)
Brand: Synology
SKU: RS822RP+

Overview

The Synology RackStation RS822RP+ is a 4-bay 1U rackmount NAS engineered for small and medium-sized businesses that need centralized data storage with built-in redundancy. Delivering over 2,103 MB/s sequential read and 1,074 MB/s sequential write throughput, it handles file sharing, data backup, and synchronization workloads with consistent performance. The unit ships diskless, accepting 3.5-inch SATA drives or 2.5-inch SSDs, and can scale from 4 to 8 total drives by attaching a single Synology RX418 expansion unit. An optional SSD cache further improves random IOPS for latency-sensitive applications like virtualization or database hosting.

Network connectivity starts with four 1GbE ports that support failover and Link Aggregation for improved throughput and reliability, with optional 10GbE and 25GbE expansion cards available for environments demanding higher bandwidth. The defining feature of the RS822RP+ is its redundant power supply, which ensures the NAS remains operational if one power supply fails—a critical reliability feature for businesses that cannot afford unplanned downtime. Running Synology's DiskStation Manager (DSM) operating system, the RS822RP+ provides access to a mature ecosystem of backup, surveillance, collaboration, and storage management applications, making it a versatile foundation for SMB IT infrastructure in a space-efficient 1U rack form factor.

Pros & Cons

👍 Pros

Redundant power supply provides hardware-level protection against power supply failure
Scalable to 8 drives via the RX418 expansion unit without replacing the NAS
Sequential read throughput over 2,100 MB/s supports demanding file transfer workloads
Four 1GbE ports with failover and Link Aggregation plus optional 10/25GbE expansion
Compact 1U rackmount form factor fits standard server racks efficiently

👎 Cons

Sold diskless, so total deployment cost increases significantly with drive purchases
Limited to 4 bays natively, which may be insufficient for larger storage needs without the expansion unit
The four 1GbE ports may bottleneck high-throughput workloads without purchasing optional 10GbE expansion
1U depth and fan noise may not suit quiet office environments
Expansion is limited to a single RX418 unit, capping total capacity at 8 drives

Frequently Asked Questions

Does the RS822RP+ come with hard drives included?

No, the RS822RP+ is sold diskless. You need to purchase compatible 3.5-inch SATA hard drives or 2.5-inch SATA SSDs separately.

Can I expand storage beyond the four built-in bays?

Yes. By connecting one Synology RX418 expansion unit, you can scale the RS822RP+ up to 8 total drives without replacing the NAS itself.

What happens if one of the two power supplies fails?

The redundant power supply design means the RS822RP+ continues operating normally on the remaining power supply, preventing downtime while you replace the failed unit.

Can I add faster network connectivity than the built-in 1GbE ports?

Yes. The RS822RP+ supports optional 10GbE and 25GbE network expansion cards for environments that require higher throughput than the four built-in 1GbE ports provide.

Does this NAS support SSD caching?

Yes. You can install SSDs as a read or read-write cache to boost random IOPS performance for frequently accessed data, improving responsiveness for applications like virtual machines or databases.
