Synology DS3622xs+ NAS is widely recognized as a powerhouse network-attached storage solution designed for professionals, creative studios, and small-to-medium enterprise environments. In 2026, data management demands have grown exponentially, and this configuration—bundled with a Synology DS223 DiskStation NAS unit powered by a Realtek RTD1619B Quad-Core processor, 2GB RAM, and dual 4TB WD Red Plus drives (total 8TB storage)—offers a balanced mix of performance, reliability, and scalability for modern workflows.
This review explores everything you need to know about this NAS setup, including its hardware capabilities, real-world performance, strengths, limitations, and whether it is worth investing in for long-term data storage, backup, and media management.
Overview and Core Architecture
The Synology DS3622xs+ NAS ecosystem is built around the idea of centralized data control. Unlike traditional external drives, this system functions as a dedicated server that allows multiple users and devices to access files simultaneously over a network. The inclusion of dual WD Red Plus 4TB drives ensures consistent NAS-grade reliability, optimized for 24/7 workloads.
At its core, the system uses a Realtek RTD1619B quad-core CPU, which is designed for energy-efficient multitasking. Combined with 2GB RAM, it can handle essential workloads such as file synchronization, multimedia streaming, surveillance storage, and backup automation without significant lag under moderate load conditions.
Key Features of Synology DS3622xs+ NAS System
This NAS system stands out due to its enterprise-grade features packed into a compact 2-bay design. Despite its small footprint, it delivers functionality typically seen in larger server setups.
1. High-Capacity 8TB Storage Configuration
With two 4TB WD Red Plus drives, users get a total of 8TB raw storage. These drives are specifically engineered for NAS environments, ensuring vibration resistance, heat management, and long-term durability. This makes it ideal for storing large datasets, backups, and multimedia libraries.
2. Gigabit Ethernet Connectivity
The 1x RJ-45 1GbE LAN port ensures stable network communication for home and office environments. While not multi-gig, it is optimized for consistent throughput, making it suitable for streaming and file sharing tasks.
3. Efficient Quad-Core Processing
The Realtek RTD1619B processor balances power efficiency with performance. It supports multiple simultaneous tasks such as file indexing, media streaming, and backup scheduling without major performance drops.
4. Synology DSM Operating System
One of the strongest advantages of this system is Synology DiskStation Manager (DSM), which provides an intuitive interface for managing files, users, security, and cloud synchronization. It also supports third-party applications for productivity and automation.
Real-World Performance and Usability
In real-world usage scenarios, the Synology DS3622xs+ NAS performs exceptionally well for its class. File transfers over a gigabit network remain stable and consistent, with minimal fluctuations even under simultaneous access by multiple devices.
For media streaming, the NAS can handle 4K video playback across compatible devices using Plex or Synology’s native media server. While heavy transcoding tasks may push the CPU limits, direct streaming remains smooth and reliable.
Backup operations are another strong point. Whether you are using Windows Backup, Time Machine, or Synology Hyper Backup, the system efficiently schedules and manages incremental backups without interrupting ongoing tasks.
For businesses, this NAS can serve as a central file hub, allowing teams to collaborate on documents, access shared folders, and maintain version control efficiently.
Advantages and Limitations
| Pros | Cons |
|---|---|
| Reliable NAS-grade WD Red Plus drives | Limited to 2GB RAM in base configuration |
