    View Latest Price

    The UGREEN NAS DH4300 Plus stands out for its combination of large storage capacity, multimedia features, and user-friendly setup, making it a top choice for home users needing reliable backup and media management. Compared with the Synology DS423, it offers more multimedia integrations like 4K HDMI output and AI photo album capabilities, but lacks the extensive software ecosystem and advanced data protection options of Synology.

Its easy setup process and support for up to 64TB make it a practical choice for those just starting to build a private cloud. Compared to the UGREEN DH4300 Plus, it offers fewer bays and lower capacity but remains straightforward and affordable. Its layered security features and remote access are suitable for personal use, though it lacks support for Docker and virtual machines, limiting expandability for tech-savvy users. This NAS suits beginners or small households prioritizing ease of use over advanced features.

    Pros:
    • User-friendly setup and operation
    • Supports up to 64TB capacity
    • AI photo tagging enhances organization
    Cons:

    Best for Power Users and Small Businesses

    View Latest Price

    The UGREEN NAS DXP4800 Pro is a powerhouse tailored for demanding workflows, offering an Intel Core i3 processor, 8GB DDR5 RAM, and extensive storage options. Its support for virtualization, Docker, and AI photo recognition makes it suitable for small businesses or advanced users needing high performance and scalability. Compared to the DH4300 Plus, it provides faster networking (10GbE), dual M.2 NVMe slots, and enterprise security, but its complexity and higher price tag make it less accessible for casual users. The absence of drives means users must supply their own disks, adding initial setup effort. This NAS is best for those with technical expertise seeking robust, expandable storage for professional environments.

    Pros:
    • High-performance Intel Core i3 CPU
    • Supports virtualization and Docker

    • M.2 NVMe Slots:2
    • Built-in Storage:128GB SSD

    Bottom line: This NAS excels for demanding workloads and professional use, but demands technical skills and a higher investment.

  4. Synology 4-Bay DiskStation DS423 (Diskless)

    Synology 4-Bay DiskStation DS423 (Diskless)

    Best for Secure Private Cloud and Data Protection

    View Latest Price

    The Synology DS423 offers a refined balance of security, data management, and expandability, making it ideal for users prioritizing private cloud access and backup integrity. Its support for up to 30 IP cameras (with extra licenses) adds surveillance capabilities, while Synology’s software ecosystem provides robust backup, snapshots, and security features. Compared with the UGREEN DH4300 Plus, it emphasizes data protection and software flexibility over multimedia output. Its diskless setup demands some technical knowledge and initial drive investment, but the extensive app ecosystem and reliable security make it well-suited for small businesses or security-conscious households.

    Pros:
    • Secure private cloud access
    • Supports up to 30 IP cameras with licensing
    • Strong backup and snapshot features
    Cons:
    • Camera licenses sold separately
    • No pre-installed drives, setup complexity
    • Requires technical knowledge for best use

  5. Buffalo LinkStation 220 4TB 2-Bay NAS Network Attached Storage with Hard Drives Included

    Buffalo LinkStation 220 4TB 2-Bay NAS Network Attached Storage with Hard Drives Included

    Best Overall for Home Users

    View Latest Price

    The Buffalo LinkStation 220 stands out for its straightforward setup and reliable data redundancy through RAID 0 and RAID 1, making it a solid choice for those who want a simple, ready-to-go backup solution. Compared with the BUFFALO LinkStation 710, it offers less performance but is easier for beginners and more affordable, especially with pre-installed drives. Its 4TB capacity suits small households, but the limited maximum storage and unspecified enclosure durability mean it might fall short for users needing more scalable or robust options. The inclusion of drives simplifies initial setup, but the device’s overall build quality remains uncertain. This pick makes the most sense for home users seeking a plug-and-play backup device with basic security features.

    Pros:
    • Simple setup with included drives
    • Supports RAID 0 and 1 for redundancy and performance
    • Secure file sharing with access controls
    • Compact and lightweight design
    Cons:
    • Limited to 4TB total capacity, not expandable
    • Build quality of enclosure is unspecified
    • Some features depend on specific macOS versions

    Best for: Home users needing reliable, easy-to-use backup with minimal configuration

    Not ideal for: Power users or small offices requiring larger or scalable storage solutions

    • Storage Capacity:4TB (2x2TB drives)
    • Number of Bays:2
    • RAID Support:Yes (RAID 0 and RAID 1)
    • Weight:454 grams
    • Color:Black
    • Compatible Devices:Desktop, Laptop
    • Mounting Type:Tabletop
    • Warranty:2 years

  6. BUFFALO LinkStation 710 4TB 1-Bay NAS Network Attached Storage with HDD Included

    BUFFALO LinkStation 710 4TB 1-Bay NAS Network Attached Storage with HDD Included

    Best for Small Offices Needing Speed and Cloud Integration

    View Latest Price

    The BUFFALO LinkStation 710 excels with its high performance, offering up to 7x faster data access than the LS 200, and built-in cloud features that streamline remote backups and sharing. Unlike the LinkStation 220, which targets home users, this model is geared toward small offices or tech-savvy households that need quick data transfers and better integration with cloud services. Its single drive bay limits expandability, but the included HDD and 2-year warranty provide a ready-to-use setup. The interface might seem complex for less experienced users, and remote access requires a network connection, which could be a drawback for some. This device is ideal for those prioritizing speed and cloud capabilities over large storage capacity or scalability.

    Pros:
    • Fast performance with up to 7x speed increase
    • Includes HDD and 2-year warranty
    • Supports cloud and remote access
    • Secure data with encryption and access controls
    Cons:
    • Limited to one drive bay, no expandability
    • Remote setup may be complex for some
    • Requires network for remote access

    Best for: Small office users or tech-savvy home users needing fast backup and remote access

    Not ideal for: Users requiring larger storage capacity or multi-user environments with extensive needs

    • Capacity:4TB
    • Number of Bays:1
    • Performance:Up to 7x faster than LS 200
    • HDD Included:Yes
    • Compatibility:Windows, MacOS
    • Warranty:2 years

    Bottom line: This NAS suits those who need quick backups, cloud support, and minimal fuss in a small office or tech-savvy home environment.

  7. QNAP TR-004 4-Bay USB Type-C Direct Attached Storage (DAS) with Hardware RAID (Diskless)

    QNAP TR-004 4-Bay USB Type-C Direct Attached Storage (DAS) with Hardware RAID (Diskless)

    Best for Expandability and Multi-OS Compatibility

    View Latest Price

    The QNAP TR-004 offers extensive flexibility, supporting RAID 0, 1, 5, JBOD, and individual disks, making it ideal for users who want to customize their storage setup. Compared to dedicated NAS models like the Synology DS423, it doesn’t serve as a network device but excels as a direct-attached solution with hardware RAID, perfect for backups from multiple sources or expanding existing storage. Its lockable bays enhance security during transport or in shared environments. However, it lacks NAS-specific features like remote access or cloud integration, and it cannot recognize data transferred from NAS devices without additional setup. This device is best for users needing a versatile, high-capacity external enclosure that can serve as a backup hub or storage expansion.

    Pros:
    • Supports multiple RAID configurations for redundancy
    • Compatible with Windows, macOS, and Linux
    • Lockable drive bays for security
    • Plug-and-play with USB Type-C interface
    Cons:
    • No native NAS functions or remote access
    • Limited to external storage, not a network device
    • Requires additional setup for data management

    Best for: Power users and IT professionals needing flexible, secure external storage for multiple operating systems

    Not ideal for: Home users seeking simple, standalone NAS solutions with easy remote access

    • Number of Bays:4
    • Interface:USB Type-C
    • Supported Systems:Windows, macOS, Linux
    • RAID Support:RAID 0, 1, 5, JBOD, individual
    • Includes:USB Type-C to Type-A cable
    • Lockable Bays:Yes

    Bottom line: This enclosure is ideal for tech-savvy users needing customizable, secure external storage with RAID support, not for those seeking a straightforward NAS.

  8. TERRAMASTER D4-320 External Hard Drive Enclosure – 4 Bay USB 3.2 Gen2, Type-C, Hot Swappable, Plug and Play

    TERRAMASTER D4-320 External Hard Drive Enclosure - 4 Bay USB 3.2 Gen2, Type-C, Hot Swappable, Plug and Play

    Best for High-Speed External Storage Without RAID

    View Latest Price

    The TERRAMASTER D4-320 is a high-speed external enclosure supporting USB 3.2 Gen2 with transfer rates up to 10Gbps, making it ideal for quick backups and large file transfers. Unlike the QNAP TR-004, which supports RAID, this model does not, focusing instead on straightforward, fast external storage. Its hot-swappable bays allow for easy disk replacement and expansion, but it doesn’t offer RAID options or network connectivity, limiting its role as a backup device to external drives. It’s a good choice for users who need rapid data transfer and large capacity drives but don’t require RAID or NAS features. This makes it less suitable for multi-device or network-based backups.

    Pros:
    • High transfer speeds up to 10Gbps
    • Hot-swappable and tool-free drives
    • Supports large capacity drives up to 30TB each
    • Quiet operation with good heat management
    Cons:
    • No RAID support or network features
    • Limited to external storage, not a NAS
    • Requires compatible drives for optimal performance

    Best for: Content creators and professionals needing rapid external storage for backups or large data transfers

    Not ideal for: Home users seeking a networked backup solution or RAID configurations

    • Number of Bays:4
    • Interface:USB 3.2 Gen2 Type-C
    • Max Data Transfer Rate:10Gbps
    • Supported Drive Types:3.5-inch SATA HDD, 2.5-inch SATA HDD, SSD
    • Maximum Drive Capacity:30TB per drive
    • Total Capacity:120TB

    Bottom line: This enclosure is ideal for users needing ultra-fast external storage without the complexity of RAID or network functions.

  9. TERRAMASTER F4-425 4-Bay NAS Storage Diskless

    TERRAMASTER F4-425 4-Bay NAS Storage Diskless

    Best Overall for Performance and Flexibility

    View Latest Price

    The TERRAMASTER F4-425 stands out for its combination of a powerful Intel x86 quad-core processor and 4GB of RAM, making it a strong choice for users who want reliable backup with multimedia streaming capabilities. Unlike the Synology DS425+ which emphasizes a compact design, this model offers higher raw performance, especially for transcoding 4K media and multi-user access. However, being diskless, it requires additional hard drives, and its plastic enclosure may raise durability concerns over time. Its 2.5GbE LAN ports deliver faster network speeds than many competitors, making it ideal for home or small office environments that need a versatile backup solution that can handle media and multi-device access seamlessly.

    Pros:
    • High-performance quad-core processor handles multitasking well
    • Supports 4K transcoding and multimedia streaming
    • Fast 2.5GbE network interface for quick data transfer
    • Mobile app setup simplifies configuration
    Cons:
    • Requires separate purchase of hard drives
    • Plastic enclosure may be less durable over time
    • Limited to 4 bays, not ideal for very large storage needs

    Best for: Tech-savvy home users or small offices seeking high performance and multimedia support for backup and streaming.

    Not ideal for: Beginners or those seeking a ready-to-use, all-in-one device with included drives and simple setup.

    • Processor:Intel x86 quad-core
    • RAM:4GB
    • Number of Bays:4
    • Max Storage Capacity:120TB (4 x 30TB)
    • Network Interface:2.5GbE LAN
    • Supported Protocols:DLNA, Plex, Emby, Jellyfin
    • Operating Environment:Home
    • Noise Level:21dB
    • Dimensions:8.74″D x 7.05″W x 6.06″H

    Bottom line: This NAS is best suited for users who need a high-performance, flexible backup device with multimedia capabilities and are comfortable managing hardware components.

  10. BUFFALO LinkStation 210 4TB 1-Bay NAS Network Attached Storage with HDD Included

    BUFFALO LinkStation 210 4TB 1-Bay NAS Network Attached Storage with HDD Included

    Best Value for Simplicity and Cost-Effective Backup

    View Latest Price

    Compared to more complex 4-bay options like the UGREEN DXP4800 Plus, the BUFFALO LinkStation 210 offers an easy-to-use, single-drive solution with pre-included HDDs, making it perfect for users who want straightforward backup without technical fuss. Its 4TB capacity is limited, especially when compared with the expandable options of multi-bay models, but for small households with modest storage needs, it provides a reliable, subscription-free cloud alternative. The device’s simple setup and US-based support make it accessible for less tech-savvy users. The main tradeoff is its limited capacity and single drive bay, which restricts future expansion and redundancy options, making it less suitable for those with larger or growing backup requirements.

    Pros:
    • Easy to set up and operate with included HDD
    • Secure file sharing and access controls
    • No subscription fees or complex management
    Cons:
    • Limited to 4TB total capacity
    • Single drive bay restricts redundancy options
    • Build quality details are unspecified, raising questions on durability

    Best for: Home users needing a simple, plug-and-play backup solution with included drives and minimal setup.

    Not ideal for: Power users or small offices requiring scalable storage or advanced features like RAID support.

    • Capacity:4TB
    • Drive Bays:1
    • Included Drives:HDD included
    • Weight:2.43 pounds
    • Color:Black
    • Compatible Devices:Desktop, Laptop

    Bottom line: Ideal for small households seeking an affordable, simple backup device with included storage and minimal fuss.

  11. UGREEN NAS DXP4800 Plus 4-Bay Desktop NAS with Intel Pentium Gold 8505, 8GB DDR5 RAM, 128GB SSD, 10GbE, 2.5GbE, M.2 NVMe Slots, 4K HDMI, Diskless

    UGREEN NAS DXP4800 Plus 4-Bay Desktop NAS with Intel Pentium Gold 8505, 8GB DDR5 RAM, 128GB SSD, 10GbE, 2.5GbE, M.2 NVMe Slots, 4K HDMI, Diskless

    Best for Power Users and Small Offices Seeking High-Speed, Advanced Features

    View Latest Price

    The UGREEN NAS DXP4800 Plus offers a level of performance that surpasses typical home backup solutions, thanks to its Intel Pentium Gold 8505 processor, 8GB DDR5 RAM, and 10GbE port. This model is tailored for users who need fast, secure, and flexible data management, including support for Docker containers, virtual machines, and AI photo organization. In comparison with the Synology DS425+, it provides more raw power and future-proof features, but at the expense of a more complex initial setup and higher cost due to the absence of included drives. Its diskless design means users must purchase compatible hard drives separately, adding to total cost. This NAS makes the most sense for tech-savvy users or small businesses with demanding backup and data management needs.

    Pros:
    • Powerful Intel Pentium Gold processor handles multitasking
    • Supports 10GbE for ultra-fast data transfer
    • Includes M.2 NVMe slots and 128GB SSD for cache or OS
    • Supports advanced features like Docker and VMs
    Cons:
    • Requires separate purchase of hard drives, increasing cost
    • Setup can be complex for non-technical users
    • Higher price point compared to simpler models

    Best for: Small offices or advanced home users who prioritize speed, expandability, and powerful features for backup and data handling.

    Not ideal for: Less technical users or those wanting an all-in-one, ready-to-go device with included drives.

    • Processor:Intel Pentium Gold 8505
    • RAM:8GB DDR5
    • Built-in Storage:128GB SSD
    • Network Ports:1 x 10GbE, 1 x 2.5GbE
    • M.2 NVMe Slots:2
    • Maximum Storage Capacity:144TB
    • Supported OS:Windows, macOS, Linux, iOS, Android
    • Warranty:2 years

  12. Synology DiskStation DS425+ (Diskless, 4-Bay NAS)

    Synology DiskStation DS425+ (Diskless, 4-Bay NAS)

    Best for Versatility and Ease of Use

    View Latest Price

    The Synology DS425+ combines a compact design with robust software support via DiskStation Manager, making it an excellent choice for users who value versatility and user-friendly management. Its 2.5GbE network ports deliver fast data transfer, and support for up to 80TB of storage provides ample room for backups and media. Compared to the TERRAMASTER F4-425, the Synology excels in its intuitive interface and extensive app ecosystem, but it requires users to acquire compatible drives separately, and setup may be more involved for newcomers. Its sturdy metal enclosure and 3-year warranty reinforce its reliability. The DS425+ suits users who want a reliable, feature-rich backup and data sharing device without the need for high-end hardware or media processing.

    Pros:
    • Supports up to 80TB of storage capacity
    • Runs on intuitive DiskStation Manager software
    • Supports multiple backup, sharing, and surveillance apps
    • Compact, desktop-friendly design
    Cons:
    • Requires compatible drives, not included
    • Setup can be complex for beginners
    • Limited to the hardware compatibility list from Synology

    Best for: Home or small office users who prefer a straightforward, versatile backup solution with easy software management.

    Not ideal for: Tech enthusiasts seeking maximum hardware performance or media transcoding beyond typical needs.

    • Product Type:System Cabinet
    • Dimensions:8.78 x 7.83 x 6.54 inches

Factors to Consider When Choosing Best 4 Bay NAS For Backup

Choosing the best 4 bay NAS for backup involves considering both your current storage needs and potential future growth. It’s important to understand how hardware specs, network capabilities, and software features align with your backup routines. Avoiding common pitfalls, like underestimating storage capacity or neglecting network speed, can save you money and frustration. This guide covers key factors to help you make an informed decision that balances performance, ease of use, and budget.

Performance and Hardware Specifications

Look for a NAS with a capable processor and sufficient RAM, especially if you plan to run multiple backup tasks or access files frequently. High-performance models with multi-core CPUs and 4GB or more RAM can handle larger backups faster and more reliably. Consider network interfaces—10GbE or 2.5GbE ports provide faster data transfer, which is essential in environments with large files or multiple users. Skimping on hardware can lead to slow backups and sluggish performance, making this an area worth investing in for professional use.

Ease of Use and Management

An intuitive interface and robust management tools reduce setup time and ongoing maintenance. Brands like Synology and QNAP offer user-friendly apps and clear documentation, which are invaluable for less tech-savvy users. Features like automated backups, remote access, and mobile apps simplify data management. Beware of models with overly complex setups or limited software support, as these can turn backup routines into headaches. Prioritize solutions with proven software ecosystems and active support communities.

Connectivity and Network Speed

Faster network interfaces, such as 10GbE, enable quicker backups and file sharing, especially in professional or multi-user setups. Consider your existing network infrastructure—upgrading to higher-speed ports might be necessary for optimal performance. Wireless connectivity is generally insufficient for large backups, so wired Ethernet remains preferable. Also, look for models supporting link aggregation to combine multiple Ethernet ports, further boosting transfer speeds and redundancy.

Expandability and Future-Proofing

Check if the NAS supports additional RAM or drives for future capacity needs. Some models allow SSD caching, which can significantly improve performance for backup and retrieval tasks. Hardware upgrade options extend the lifespan of your device and adapt to growing data demands. Conversely, models with limited upgrade paths might seem cheaper upfront but could incur additional costs or require replacement sooner, making them less economical long-term.

Price and Value

Prices vary widely based on hardware features and software capabilities. Budget models are suitable for basic backup needs but lack advanced features like high-speed ports or large RAM. Premium options offer speed, expandability, and enhanced security but come at a higher cost. Consider your backup volume, potential growth, and how much you’re willing to invest. Sometimes, paying a bit more upfront yields better performance and peace of mind over time.

Frequently Asked Questions

Can I use a 4 bay NAS for both backup and media streaming?

Absolutely. Many 4 bay NAS devices are versatile enough to handle backups and media streaming simultaneously. Devices like Synology DiskStation DS423 include media server apps that support streaming to multiple devices, alongside robust backup solutions. The key is ensuring the NAS has sufficient processing power and network bandwidth to manage both tasks smoothly. Keep in mind, running both functions intensively can impact overall performance, so choose a model with hardware that can handle multitasking if you plan to do so regularly.

Is it better to buy a diskless NAS or one with drives included?

Choosing a diskless NAS provides maximum flexibility since you can select drives that meet your capacity and performance needs. It also allows for future upgrades or replacements without discarding the entire device. However, it requires buying drives separately, which can add to initial costs and complexity. Pre-populated models with drives included are simpler to set up but often come with limited flexibility and higher overall costs. For long-term flexibility and cost control, most experienced users prefer a diskless option.

How important is network speed for backup performance?

Network speed is a critical factor, especially when backing up large files or multiple users accessing the NAS simultaneously. A 1GbE port might suffice for small-scale use, but for faster, more efficient backups, 2.5GbE or 10GbE ports become valuable. Upgrading your network infrastructure to support higher speeds can significantly reduce backup times and improve overall data access. Neglecting network capabilities can bottleneck even the most powerful NAS, so match your device’s network interfaces with your environment.

Should I prioritize software features or hardware specs?

Both matter, but the right balance depends on your needs. Robust software features—automatic backups, encryption, remote access—are essential for a seamless backup experience. Hardware specs like CPU and RAM influence how well the NAS handles multiple tasks and large data transfers. For most users, choosing a device with good software support and adequate hardware provides the best overall experience. High-end hardware without complementary software features can limit usability, so ensure both sides are aligned with your backup goals.

What capacity should I look for in a 4 bay NAS for future growth?

Start with a capacity that covers your current needs, plus some headroom for growth—generally, 4-8TB drives per bay are common. If you anticipate expanding data volume, consider models supporting larger drives or additional drives via expansion units. RAID configurations also impact usable capacity, so plan accordingly to balance redundancy and storage space. Investing in a NAS with higher capacity now can save money and hassle later, especially if you expect your backup needs to grow significantly.

Conclusion

For most users seeking a reliable, easy-to-manage backup solution, the Synology DiskStation DS423 offers excellent value with its user-friendly interface and solid performance. Those with higher speed requirements or professional workflows should consider the UGREEN NAS DXP4800 Pro for its advanced hardware and 10GbE support. Budget-conscious buyers can opt for the BUFFALO LinkStation 220, which provides straightforward backup capabilities without breaking the bank. Beginners will appreciate models with strong software ecosystems, while power users should prioritize expandability and network speed. Each of these options addresses different priorities, ensuring you find a suitable match for your backup needs in 2026.
