Synology RS422+ 4-Bay Rackmount NAS with 10GbE: A Professional Upgrade from Legacy Storage
After years of relying on an older NAS brand, I eventually reached the point where familiar hardware was no longer enough. My requirements had changed. File sizes had grown, network infrastructure had become faster, remote access had become more important, and the amount of data being managed every day demanded something more disciplined than a basic storage box. That transition is what makes the Synology RackStation RS422+ interesting. Rather than simply replacing an aging NAS with another storage appliance, this four-bay rackmount system feels like a move toward a more structured professional storage environment.
The Synology RS422+ arrives diskless, so it is important to understand that the purchase is for the NAS platform itself rather than a ready-to-use array with hard drives included. That approach is actually attractive to experienced users because it allows storage capacity and drive selection to be matched to the workload. The package also includes the E10G22-T1-Mini network upgrade module, adding a 10GbE RJ-45 connection to the system. For anyone moving away from an older NAS platform and upgrading the network at the same time, that combination can be a particularly useful foundation.
My focus with a system like this is not simply specifications on a product page. I want to know whether the hardware, operating environment, connectivity, expandability, and day-to-day management experience make sense after years of using another ecosystem. The RS422+ makes a strong case by combining a compact four-bay rackmount design with Synology’s software environment and an available path to significantly faster Ethernet.
Why I Switched from an Older NAS Brand
Changing NAS brands is never a decision I make casually. A NAS eventually becomes much more than a collection of drives. It holds backups, project files, archives, media, shared folders, snapshots, and sometimes application data. Moving to another platform means learning a new management environment and rebuilding trust in the hardware.
What attracted me to Synology was the balance between hardware and software. The RS422+ is designed around a dedicated rackmount form factor, while Synology’s DiskStation Manager ecosystem provides the administrative layer that turns the hardware into a broader storage platform. For professionals, that distinction matters. A NAS should not require constant attention just to perform routine storage tasks.
The four-bay configuration also makes sense for users who have outgrown two-bay storage but do not necessarily need an enormous enterprise chassis. Four drive bays provide enough flexibility for a meaningful redundant storage configuration while keeping the physical footprint manageable inside a rack.
Key Features of the Synology RS422+
- Four drive bays: The four-bay chassis provides a practical balance between capacity, redundancy, and physical size.
- Rackmount design: The RS422+ is built for organized rack-based installations rather than sitting as a conventional desktop NAS.
- Diskless configuration: Drives can be selected separately according to capacity, workload, and storage strategy.
- 10GbE upgrade: The included E10G22-T1-Mini module adds 1x 10GbE RJ-45 connectivity for compatible high-speed networking environments.
- Synology DSM: The software platform provides centralized administration and a broad collection of storage and productivity capabilities.
- Network-focused architecture: The system is well suited to environments where multiple clients need shared access to centralized data.
- Professional rack integration: Its rackmount format makes it easier to incorporate into a structured server or networking setup.
Hardware Perspective: What Stands Out
The first thing I appreciate is the physical design. Coming from an older NAS platform, moving to a rackmount unit changes the entire way the storage system fits into a workspace. Instead of treating the NAS as another desktop accessory, the RS422+ can become part of a dedicated infrastructure stack alongside switches, patch panels, UPS equipment, and other network hardware.
The four-bay arrangement is equally important. Storage planning becomes much easier when there are enough bays to build redundancy without immediately requiring a large chassis. Depending on the drives and RAID or storage configuration selected, users can prioritize capacity, redundancy, or a combination of both. Because this is a diskless system, the final storage characteristics depend heavily on the drives installed, so buyers should plan the array around their actual workload rather than treating the NAS enclosure as the complete solution.
The 10GbE upgrade is arguably the biggest reason this configuration caught my attention. Traditional gigabit Ethernet can become a serious bottleneck when large files are moving between a workstation and centralized storage. With compatible 10GbE networking equipment and client hardware, the additional bandwidth can make a noticeable difference in high-volume workflows such as media production, large project archives, workstation backups, and frequent transfers of large datasets.
10GbE Networking in Real-World Use
Adding 10GbE does not magically make every NAS workload ten times faster. That is an important distinction. Actual performance depends on the installed drives, RAID configuration, network switch, client hardware, protocols, file sizes, and the number of simultaneous users. Nevertheless, increasing the network ceiling removes one of the most obvious limitations found in older gigabit-based NAS installations.
For me, the biggest advantage of 10GbE is not chasing a benchmark number. It is reducing the amount of time spent waiting for large transfers. When a workstation repeatedly moves large project folders, backup sets, raw media, or extensive archives, network throughput becomes part of daily productivity. A faster connection can make centralized storage feel much closer to local storage in the right environment.
The RJ-45 format is also convenient for users upgrading an existing network. It avoids forcing the entire setup into a completely different cabling ecosystem simply to gain higher bandwidth. Of course, the rest of the network needs to support 10GbE for the upgrade to deliver its full value.
Performance and Daily Workflow
After switching from an older NAS brand, I pay close attention to how much effort is required to perform routine administration. A good NAS should make storage management predictable rather than turning every maintenance task into a technical project. Synology’s DSM environment is one of the major reasons the RS422+ stands out as a professional-oriented solution.
File sharing, user management, storage configuration, backup planning, monitoring, and other administrative tasks are handled through the software environment rather than through a collection of disconnected utilities. That integrated approach is valuable when the NAS becomes part of a working environment instead of serving as occasional backup storage.
The RS422+ also benefits from being a dedicated appliance. There is a clear difference between installing storage drives into a general-purpose computer and deploying a purpose-built NAS. The latter is designed around centralized storage responsibilities, making it easier to establish a consistent workflow for shared data and backups.
For professional users, performance should also be judged by consistency. A NAS that performs well for one large transfer but becomes difficult to manage afterward is not necessarily a better system. The real benefit comes from predictable storage administration, dependable access, sensible monitoring, and the ability to expand the workflow as requirements increase.

Who Should Consider This NAS?
The RS422+ makes the most sense for users who have already moved beyond entry-level storage requirements. It is especially appealing to small businesses, professional workgroups, IT administrators, content creators, offices with centralized backups, and experienced home users building a serious network infrastructure.
If the goal is simply to store a few documents and photographs, a four-bay rackmount NAS with a 10GbE upgrade may be more capability than necessary. But if the NAS is expected to become a central repository for multiple computers, backups, project files, media, and shared data, the additional infrastructure makes more sense.
The included 10GbE module also makes this configuration particularly interesting for users who are already upgrading their switches and workstations. Instead of purchasing a slower NAS and replacing it later, this setup provides a more forward-looking networking configuration from the beginning.
Installation and Storage Planning
Because the unit is diskless, installation begins with an important decision: selecting appropriate drives. NAS workloads can be very different from desktop workloads, so the storage media should be chosen with continuous operation, workload characteristics, capacity requirements, and redundancy in mind.
Once the physical drives are installed, the storage pool and volume strategy should be planned carefully. Redundancy is especially important when the NAS becomes a central repository. RAID can help maintain availability when a drive fails, but it should never be confused with a complete backup strategy. Critical data should still have an independent backup.
Network planning deserves similar attention. To use the 10GbE interface effectively, the NAS, network switch, cabling, and client device should all support an appropriate 10GbE connection. Otherwise, the NAS can still function perfectly well, but the network connection may remain the limiting factor.
Long-Term Value After Switching Brands
The biggest lesson I have learned from moving away from an older NAS brand is that the ecosystem matters nearly as much as the hardware. A NAS can have impressive specifications, but if administration is frustrating or the platform does not fit the way you work, the initial savings may not remain valuable over several years.
The RS422+ feels like a system designed with the longer view in mind. The four bays offer a reasonable starting point, DSM provides a broad management environment, and the 10GbE upgrade gives the network side room to grow. That combination is more compelling to me than a product that simply offers more raw capacity without a clear path for infrastructure development.
There is also something reassuring about moving to a rackmount platform when storage becomes mission-critical. The physical organization is cleaner, the networking environment can be structured more professionally, and the NAS becomes part of an intentional infrastructure rather than an isolated box sitting wherever there happens to be space.
For anyone currently operating an aging NAS from another manufacturer, I would evaluate the transition in terms of the entire workflow: storage requirements, network speed, backup strategy, software management, rack space, drive compatibility, and future expansion. When those requirements line up, the Synology RS422+ becomes a convincing upgrade rather than simply another NAS purchase.

Frequently Asked Questions
Is the Synology RS422+ sold with hard drives?
No. This configuration is diskless, meaning the storage drives are purchased separately. This gives the buyer flexibility to select suitable NAS drives and determine the desired capacity and redundancy configuration.
Does the RS422+ support 10GbE?
This configuration includes the Synology E10G22-T1-Mini network upgrade module, which adds one 10GbE RJ-45 connection. To take advantage of the higher speed, the rest of the network path should also support 10GbE.
Is four-bay storage enough for professional use?
For many small-business, professional, and advanced home workflows, four bays provide a useful balance between capacity and physical size. Users with extremely large storage requirements or extensive expansion plans may eventually need a larger NAS platform.
Will 10GbE make file transfers ten times faster?
Not necessarily. Network speed is only one part of NAS performance. Drive speed, RAID configuration, file size, client hardware, network infrastructure, protocols, and simultaneous workloads all influence actual transfer performance.
Is the RS422+ suitable for replacing an older NAS from another brand?
It can be an excellent candidate for that kind of upgrade, particularly when the existing system is limited by aging hardware, slower networking, or an outdated management environment. However, migration should be planned carefully, with independent backups maintained before moving important data.
Does the rackmount design make sense for a home user?
It can, especially for an enthusiast or professional who already has a network rack or dedicated equipment space. For someone who only needs basic file storage and has no rack infrastructure, a desktop NAS may be simpler.
Is this a good choice for large media files?
The combination of multiple drive bays and 10GbE networking can be attractive for large-file workflows, including media and creative projects. Actual performance will depend on the selected drives, storage configuration, workstation, and network equipment.
Does RAID replace a backup?
No. RAID can provide redundancy and help maintain access when a drive fails, but it does not protect against every form of data loss. Important files should have an independent backup strategy.
Final Verdict
After transitioning from an older NAS brand, the Synology RackStation RS422+ stands out because it addresses more than storage capacity. It provides a professional four-bay rackmount foundation, a mature software environment, flexible diskless configuration, and, with the included E10G22-T1-Mini, a meaningful move toward 10GbE networking.
I would not recommend it simply because it is a Synology product. I would recommend it when the requirements justify a dedicated rackmount NAS and the network is ready to take advantage of faster connectivity. For professionals who have outgrown basic gigabit storage and want a more organized, scalable, and management-focused platform, this configuration represents a substantial step forward from many older NAS setups.
The combination of four bays and 10GbE makes the RS422+ particularly appealing as an infrastructure upgrade. It is not just about having somewhere to put files; it is about building a centralized storage system that can support faster workstations, larger datasets, stronger backup routines, and a more professional network architecture. For me, that is the real reason this Synology configuration earns serious consideration as a replacement for an aging NAS platform.
