What Is a NAS?
A Network Attached Storage (NAS) device is a dedicated computer connected to your network that provides centralized storage.
Instead of plugging an external hard drive into one computer, a NAS can allow multiple authorized devices to access files through your local network.
You can use a NAS for:
- File storage
- Computer backups
- Photo libraries
- Video storage
- Media streaming
- Cloud synchronization
- Remote access
- Surveillance
- Home labs
Why Buy a NAS?
A NAS can provide several advantages over traditional external storage.
Centralized Storage
All your files can be stored in one location.
Automatic Backups
A NAS can automatically back up computers and mobile devices depending on its software.
Multiple Users
Family members or employees can access shared folders with individual permissions.
Private Cloud
You can access selected files remotely without relying entirely on third-party cloud storage.
Expandable Storage
Multi-bay systems can accommodate several drives and larger capacities.
How Many Drive Bays Do You Need?
The number of bays is one of the most important NAS purchasing decisions.
| NAS Bays | Best For |
|---|---|
| 1 | Basic network storage |
| 2 | Home users & backups |
| 4 | Home offices & small businesses |
| 5–6 | Advanced users |
| 8+ | Businesses & large storage environments |
A two-bay NAS is an excellent starting point for many households.
A four-bay NAS offers considerably more flexibility for capacity and redundancy.
What Is RAID?
RAID allows multiple drives to work together in different configurations.
Common configurations include:
RAID 0
Focuses on performance and combines drive capacity, but provides no redundancy.
RAID 1
Mirrors data between two drives, providing redundancy.
RAID 5
Uses distributed parity and requires multiple drives.
RAID 6
Provides additional redundancy compared with RAID 5.
RAID 10
Combines mirroring and striping for performance and redundancy.
Remember that RAID is not a backup. A NAS should still have a separate backup of important data.
Compare NAS HDD vs. SSD
| Feature | NAS HDD | NAS SSD |
|---|---|---|
| Cost per TB | Lower | Higher |
| Capacity | Very high | High |
| Sequential storage | Good | Excellent |
| Random performance | Lower | Much higher |
| Noise | Higher | Very low |
| Power use | Higher | Lower |
| Best for | Large storage | Performance |
For large media libraries and backups, NAS hard drives generally offer better value.
SSDs make more sense when you need high random performance, low latency, or intensive workloads.
What Should You Look for in a NAS?
1. Drive Bays
Choose a system with enough bays for both current storage and future growth.
2. Networking
A basic 1GbE connection is adequate for many home users.
A 2.5GbE or faster connection can significantly improve file transfer performance when your computers and network infrastructure support it.
3. CPU and RAM
More powerful processors and additional RAM can help with:
- Multiple users
- Containers
- Virtual machines
- Media processing
- Large file transfers
- Advanced applications
4. NVMe Support
Some NAS systems include M.2 slots for SSD caching or storage.
This can improve certain workloads, but SSD caching isn’t automatically beneficial for every NAS setup.
5. Software
The NAS operating system is extremely important.
Look for:
- Easy setup
- Backup applications
- File synchronization
- Remote access
- User management
- Mobile apps
- Security updates
- Container support
Best NAS Storage Device by Use Case
| Use Case | Recommended |
|---|---|
| Best overall | Synology DS224+ |
| Best home office | Synology DS923+ |
| Best 5-bay | Synology DS1522+ |
| Best performance | QNAP TS-464 |
| Best budget | QNAP TS-233 |
| Best power user | ASUSTOR Lockerstor |
| Best value | TerraMaster F4-424 |
| Best modern hardware | UGREEN NASync |
| Best for backups | Synology |
| Best media server | QNAP |
| Best home lab | QNAP/ASUSTOR |
| Best small business | Synology/QNAP |
| Best private cloud | Synology |
NAS for Photo and Video Storage
Photographers and video creators can benefit significantly from centralized NAS storage.
A NAS can store:
- RAW photographs
- 4K video
- Project files
- Lightroom libraries
- Archived footage
- Finished projects
However, video editors working directly from a NAS should consider network speed.
A 1GbE connection can become a bottleneck when working with very large video files.
For demanding workflows, 2.5GbE, 5GbE, 10GbE, or faster networking may be more appropriate.
NAS for Home Backup
One of the best uses for a NAS is automated backup.
You can configure it to back up:
- Windows PCs
- Macs
- Smartphones
- Photos
- Documents
- Work files
A good strategy is to automate backups rather than relying on manually copying files.
For critical information, maintain an additional backup outside the NAS.
NAS Security Tips
Because a NAS is connected to your network, security should be a priority.
Use:
- Strong unique passwords
- Multi-factor authentication where available
- Regular firmware updates
- Limited user permissions
- Secure remote-access methods
- Firewall protection
- Separate accounts for users
- Regular backups
Avoid exposing unnecessary NAS services directly to the public internet.
Final Verdict
The Synology DS224+ is our best overall NAS storage device for most home users because it combines straightforward software, useful backup features, reliable hardware, and a mature application ecosystem.
For users who need more capacity and expansion, the Synology DS923+ and DS1522+ provide additional drive bays and greater flexibility. The QNAP TS-464 is a strong performance-focused alternative, particularly for users with a 2.5GbE network.
Budget buyers can consider the QNAP TS-233, while power users may prefer the ASUSTOR Lockerstor 4 Gen2 or TerraMaster F4-424.
Before buying, determine how much storage you need, how many users will access the NAS, whether you need RAID, what network speed you have, and which applications you plan to run.
For most households, a two-bay NAS with 1GbE networking is an excellent starting point. For small businesses, creators, and advanced users, a four-bay or larger NAS with 2.5GbE or faster networking provides more room for growth.
Most importantly, remember that RAID is not a backup. A NAS can protect against certain drive failures, but important data should also exist in a separate backup location.
