10 Best Nas Servers 2025 in the United States

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.

The QNAP TVS-h1288X-W1250-16G is a robust NAS server designed for users needing high-speed media storage and advanced functionality. With an Intel Xeon W-1250 6-core processor and 16GB of ECC RAM, it offers strong performance for handling multiple tasks and users simultaneously, making it suitable for small to medium businesses or tech-savvy home users. The server boasts 12 bays, providing ample storage capacity, which can be expanded further with RAID support for data redundancy and security, a crucial feature for anyone concerned about data loss.

Connectivity is another strong point. With two 10GbE ports and additional 2.5 Gigabit Ethernet ports, transferring large files or streaming high-definition media is quick and efficient. The multiple USB ports, including Type-C and HDMI, enhance its versatility, allowing for easy connections to various devices.

The QNAP TVS-h1288X may not be ideal for everyone. Its size and weight can be cumbersome for home use, especially if space is limited. Additionally, while it excels in performance, the initial setup and management can be complex for users without technical expertise. This may require some time to fully understand and utilize its extensive features effectively. The price point reflects its advanced specifications, which might be considered high for casual users who only need basic storage solutions.

The Asustor Lockerstor 12RD is a 12-bay NAS designed for businesses or power users needing substantial storage and reliable performance. It features a quad-core Intel Atom C3538 CPU at 2.1GHz and comes with 8GB of DDR4 RAM, which can be expanded up to 128GB. This makes it capable of handling multiple simultaneous tasks, including running virtual machines and Docker applications. The device supports RAID configurations, offering data protection and improved performance. Connectivity is strong with two standard Gigabit Ethernet ports plus two 2.5-Gigabit Ethernet ports, allowing up to 5 Gbps combined speed, and it even has a PCIe slot for adding a 10-Gigabit Ethernet card for faster network access.

The Lockerstor 12RD supports major business protocols like iSCSI/IP-SAN and NFS, and integrates well with VMware, Citrix, and Hyper-V virtualization environments, making it practical for professional use. It also includes features for access control, improving security and efficiency in business settings. Being a 2U rackmount server, it’s designed for data centers or server rooms and includes a redundant power supply, which helps maintain uptime in case of power issues.

On the downside, it’s a heavy and somewhat large unit at over 25 pounds and 3.5 inches tall, which might not suit smaller office setups. It ships diskless, so you need to buy your own hard drives separately. Noise and power consumption levels are typical for a rack-mounted NAS but may be noticeable outside dedicated server areas. This NAS is well suited for users who need large, expandable storage with solid performance and business-oriented features, especially in virtualized or networked environments.
