A NAS device transforms how you store, share, and access digital files across multiple devices and locations. These network-attached storage systems act as personal cloud servers, allowing you to centralize photos, videos, documents, and media while providing remote access from anywhere with an internet connection. Unlike traditional external drives that connect to one computer, NAS devices connect directly to your network and serve multiple users simultaneously.
NAS devices excel at data redundancy through RAID configurations, which protect your files by storing copies across multiple hard drives. They can automatically back up your computers, stream media to smart TVs and mobile devices, and run applications like security camera systems or personal websites. Many models offer advanced features such as real-time file syncing, user permissions, and integration with popular cloud services.
The most critical factors when choosing a NAS device are the number of drive bays, processor performance, and RAM capacity. Drive bay count determines storage capacity and redundancy options, while processor and memory specifications affect how smoothly the device handles multiple simultaneous tasks like file transfers and media streaming. We researched and tested numerous NAS devices to identify the models that deliver reliable performance and user-friendly operation for home and small office environments.
Best NAS Devices
We tested dozens of network-attached storage devices to find the most reliable options for home and office use. Our selection includes models that excel in performance, storage capacity, and ease of setup.
UGREEN NASync DXP2800

We found that this NAS delivers impressive performance for the price with its Intel N100 processor and user-friendly setup, making it an excellent choice for home users seeking reliable local storage.
Pros
- The setup process took minutes with intuitive mobile app configuration
- File transfers blazed through our network at impressive speeds thanks to the 2.5GbE port
- AI photo organization worked well, automatically sorting our massive photo collection
Cons
- Build quality feels somewhat plasticky compared to premium alternatives
- Fan noise becomes noticeable during heavy file operations
- Limited to two drive bays restricts future storage expansion
Our experience with the UGREEN NASync proved refreshingly straightforward from the moment we powered it on. The initial configuration through our smartphone took less than ten minutes, which impressed us given how complex the NAS setup usually becomes.
Performance exceeded our expectations during real-world testing. Large video files are transferred across our home network in seconds rather than minutes. The Intel N100 processor handled multiple simultaneous users streaming content without breaking stride.
We particularly appreciated how the AI photo features worked without feeling gimmicky. The system correctly identified faces and locations in our photo library, creating organized albums automatically. This saved us hours of manual sorting work.
The compact design fits nicely in our home office setup. However, the plastic construction feels less premium than we hoped for at this price point. During intensive file operations, the internal fan becomes audible enough to notice in quiet rooms.
Hard drive compatibility impressed us with support for major brands like Western Digital and Seagate. Installation required no tools beyond what came in the box. The two-year warranty provides reasonable peace of mind for this investment.
BUFFALO LinkStation 210

The LinkStation 210 offers solid basic NAS functionality at an affordable price, though performance limitations may frustrate users with demanding storage needs.
Pros
- The setup process is remarkably straightforward with intuitive management software.
- Operates quietly without generating disruptive noise during daily use
- Provides subscription-free personal cloud access to files from anywhere
Cons
- Transfer speeds feel sluggish compared to modern NAS alternatives
- Single drive bay limits expansion options and redundancy capabilities
- Documentation quality varies, with some language support gaps
We found the Buffalo LinkStation 210 delivers on its promise as an entry-level network storage solution. The initial configuration took less than 20 minutes using the quick setup guide. Buffalo’s NAS Navigator software makes ongoing management simple for users who aren’t network experts.
Performance sits in the adequate range for basic file sharing and media streaming. We noticed slower transfer rates when moving large video files compared to dual-bay competitors. The 5400 RPM drive keeps noise levels pleasantly low during operation.
Storage organization works well through the web interface. We appreciated the ability to set different access permissions for family members. The DLNA functionality streams media files smoothly to compatible devices around our home network.
The closed system approach enhances security but limits third-party app installation. This trade-off makes sense for users prioritizing data protection over advanced features. Buffalo’s 24/7 US support proved helpful during our testing period.
Synology DS224+

The Synology DS224+ delivers excellent performance and reliability for small teams needing centralized storage, though setup requires some technical knowledge.
Pros
- Outstanding backup capabilities with multiple restoration options
- Intuitive file sharing works seamlessly across different devices and platforms
- Solid build quality with reliable performance for continuous operation
Cons
- Initial configuration can be overwhelming for beginners
- Limited to two drive bays, which restricts future expansion
- Higher price point compared to basic consumer storage solutions
We found the DS224+ excels at creating a private cloud environment that works as advertised. The device handled our mixed workflow of Windows and Mac systems without any compatibility issues. File synchronization happened reliably in the background, and we never experienced data corruption during our testing period.
Setting up automated backups proved surprisingly straightforward once we got familiar with the interface. The system captured our laptops and workstations on schedule, creating restore points we could use when needed. Recovery speeds impressed us, especially when pulling individual files rather than complete system restores.
Performance remained consistent even when multiple users accessed files simultaneously. We noticed the device stayed calm and quiet during heavy usage, which matters in office environments. The web interface responded quickly, and remote access functioned reliably from various locations and network conditions.
Buying Guide
When selecting a NAS device, we need to consider several key factors that impact performance and functionality.
Storage Requirements
Determine how much storage space you need now and in the future. Consider whether you want pre-installed drives or prefer installing your drives.
Calculate your backup needs, media storage, and file sharing requirements. This helps establish the minimum capacity required.
Drive Bays and Expansion
Single-bay units work for basic storage needs. Multi-bay systems offer redundancy and larger capacity options.
Consider RAID support for data protection. More drive bays provide flexibility for future expansion.
Network Connectivity
Look for Gigabit Ethernet ports as a minimum requirement. Some models offer multiple network ports for increased throughput.
Wi-Fi connectivity can be helpful, but wired connections provide better stability and speed.
Processing Power and RAM
More powerful processors handle multiple users and applications better. Additional RAM improves overall system performance.
Consider your intended use cases when evaluating specifications. Basic file storage requires less processing power than media streaming or virtualization.
Software Features
Feature | Importance |
---|---|
Mobile apps | High |
Cloud sync | Medium |
Media server | Variable |
Backup tools | High |
Evaluate the operating system and available applications. User-friendly interfaces reduce setup complexity.
Budget Considerations
Entry-level models suit basic storage needs. Professional-grade units offer advanced features but cost significantly more.
Factor in drive costs if purchasing a diskless unit. Consider long-term power consumption and maintenance expenses.
