Synology 4-Bay RackStation RS822+ - Compact 1U Rack NAS

In this review the Synology 4-Bay RackStation RS822+ is presented as a compact 1U rackmount NAS aimed at branch offices and small to medium-sized businesses that need reliable, scalable on-premises storage. The bottom line: it delivers stable, consistently fast transfers and flexible expansion in a small chassis, making it a sensible platform for backups, file sharing, and synchronized workflows where predictable networked storage performance matters most. The reviewer found setup straightforward and performance strong for its class, especially when paired with optional expansions.

Key Features

• High sequential throughput: Sustained read and write speeds of over 2,103/1,074 MB/s support stable data transfers for backups and large file moves.
• Scalable storage: Base 4-bay design scales up to 8 drives with a Synology RX418 Expansion Unit for growing capacity without replacing the primary unit.
• Flexible networking: Four 1GbE ports offer failover and load balancing to keep access resilient across a small office network, and optional 10/25GbE expansions are supported for higher bandwidth needs.
• Boostable IOPS: Random IOPS can be accelerated with an optional SSD cache to improve responsiveness for small-file and database workloads.
• Compact rackmount form: The 1U chassis fits easily into constrained racks while running DiskStation Manager for a familiar Synology management experience.

Who It's For

The RS822+ is best for IT administrators at branch offices, small businesses, or teams that require reliable on-premises storage with clear upgrade paths. It is a good fit when routine backups, shared file stores, and synchronized data across locations are priorities and when a compact 1U footprint is required.

Those needing extremely high native port speeds out of the box or larger raw drive counts without expansion should consider alternatives with built-in 10/25GbE or more bays; likewise, very small home users may find a desktop NAS simpler and less costly.

Pros & Cons

Pros

• Easy to install and configure, with customers noting the unit is straightforward to set up and integrate.
• Strong sequential read/write performance that supports large transfers and backup windows.
• Flexible expansion and optional SSD cache let the system grow and improve random IOPS as needs change.
• Compact 1U chassis is rack-friendly for space-constrained environments.

Cons

• Base networking is four 1GbE ports; organizations that need higher native bandwidth will need optional expansion cards.
• Diskless configuration requires purchasing drives separately, which adds to initial cost.

Our Verdict

The Synology RS822+ is a solid, compact rack NAS for small and medium business sites that need dependable throughput, straightforward management, and clear expansion options. It represents good value for teams that plan to scale storage or add SSD caching later and who prefer a mature OS in a 1U form factor.

Frequently Asked Questions

Does the RS822+ include drives?
It ships diskless, so drives must be purchased and installed separately to meet your capacity and performance needs.

Can I add faster network ports?
Yes, optional 10/25GbE expansion cards are supported to increase network bandwidth beyond the four built-in 1GbE ports.

Will SSD cache improve performance?
Yes, adding an SSD cache is supported and can significantly boost random IOPS for small-file and database workloads.
