10 Best Nas Servers 2025 in the United States

The Synology RS422+ is a 4-bay rackmount NAS designed for small to medium business users who need reliable and efficient storage. Its 4 bays support multiple hard drives, allowing you to set up RAID configurations for data protection — a key feature for safeguarding your files. Performance-wise, it offers solid sequential read/write speeds around 600/500 MB/s, making it suitable for tasks like data backup, file sharing, and media storage without noticeable delays. The unit is compact with a 1U rack size and a shallow depth, which helps save space in server racks.

Connectivity includes dual 1GbE Ethernet ports that support failover and load balancing, ensuring stable network connections. It also allows easy upgrades to 10GbE ports, which is great if you need faster network speeds in the future. The NAS is diskless, so you’ll need to provide your own drives, which gives flexibility but also means extra cost upfront.

Synology’s software ecosystem is well-regarded for user-friendly management and useful features like data synchronization and backup tools. This model is a good pick if you want a compact, scalable NAS with reliable speeds and flexible connectivity, especially suitable for business environments requiring dependable storage solutions.

The Synology DS224+ is a compact 2-bay NAS device ideal for home users or small offices needing reliable storage and file sharing. It comes bundled with 8TB total capacity via two 4TB WD Red Plus drives, which are known for durability and good performance in NAS environments. The Intel Celeron J4125 quad-core processor and 2GB of DDR4 RAM provide enough power for everyday tasks like file backups, media streaming, and light multitasking.

It supports RAID configurations, allowing you to set up your drives to protect your data from hardware failure. Connectivity includes two 1GbE LAN ports for network link aggregation, improving speed and stability if your network supports it, plus USB 3.2 ports for adding external storage or peripherals. Synology’s software offers a user-friendly interface with security features to keep your data safe and tools to easily access or sync files remotely.

The 2GB RAM may be somewhat limited if you plan to run many apps or heavy workloads, and the 1GbE network ports might feel slow for very large file transfers compared to faster 2.5GbE or 10GbE alternatives. Noise and power consumption are typical for this class—quiet and energy-efficient enough for continuous home or small office use. This NAS is a solid choice for those seeking straightforward setup and reliable storage without the need for advanced enterprise features.

The BUFFALO TeraStation 5820DN is a solid choice for businesses needing a large and reliable network storage solution. It comes with 8 bays, each preloaded with 20TB NAS-grade hard drives, giving you a massive raw capacity of 160TB. Configured in RAID 6 out of the box, it offers about 120TB of usable space with good data protection, which is ideal for critical business data. The device supports RAID configurations, allowing flexibility depending on your needs for speed or redundancy.

Its hardware is designed for stability and security, featuring a closed system with 256-bit encryption and two-factor authentication to protect sensitive files. The built-in snapshot feature helps with quick backups and recovery, which is useful in preventing data loss from accidental deletion or ransomware attacks. Another standout is the native 10GbE Ethernet port that supports very fast file transfers without needing additional hardware upgrades, beneficial for environments with heavy data traffic.

In terms of compatibility, it works well across Windows, Mac, and Linux systems, making it versatile in mixed-OS offices. Cloud integration with services like Dropbox and Amazon S3 enables hybrid backup strategies for extra data safety. The unit is fairly large and weighs about 31.5 pounds, and while power consumption and noise levels aren’t explicitly detailed, business NAS devices like this typically balance performance with reasonable energy use and quiet operation. The 5600 RPM hard drives are optimized for NAS use but might be slower than higher RPM drives for some intensive tasks. If you need a high-capacity, secure, and business-focused NAS with strong data protection and fast network connectivity, the TeraStation 5820DN is a dependable option best suited for medium to large businesses looking for a robust desktop NAS without having to separately buy drives.
