    Asustor Drivestor 4 Gen 2 AS1204T 4-Bay NAS with Quad-Core CPU, 2.5GbE, 1GB DDR4, USB 3.0, Diskless

    Best Overall for Home and Small Office Use

    View on Amazon

    This model stands out for its balance of high-speed networking and flexible RAID options, making it ideal for users who prioritize data redundancy and media streaming. Compared with the Synology DS425+, the AS1204T offers a more straightforward setup with a focus on media and backup, but it’s limited by only 1GB of RAM, which can hinder multitasking for heavier workloads. Its 2.5GbE port ensures faster local transfers, yet the basic hardware might struggle with intensive tasks. This pick makes the most sense for small office users or home users who need reliable performance without complex features or high hardware costs.

    Pros:
    • High-speed 2.5GbE network enables faster local data transfer
    • Supports multiple RAID configurations for data safety
    • Includes enterprise-grade Btrfs snapshots for data protection
    • Good for media streaming and personal cloud storage
    Cons:
    • Limited 1GB RAM can bottleneck multitasking
    • Requires separate purchase of drives, adding to overall cost
    • Basic hardware may be insufficient for intensive workloads

    Best for: Home users and small offices seeking a reliable, high-speed NAS with RAID support.

    Not ideal for: Power users or those running virtual machines who require more RAM and processing power.

    • Processor:Realtek RTD1619B 1.7GHz Quad-Core
    • RAM:1GB DDR4
    • Network:2.5GbE Port
    • Drive Bays:4
    • Supported RAID:0/1/5/6/10
    • Connectivity:3 USB 3.0 ports
    Our verdict
    “This NAS is best suited for users who want a straightforward, high-speed device for backup and media without complex enterprise features.”
  2. UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams

    UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams

    Best Value for Large Storage and Small Team Collaboration

    View on Amazon

    This model shines for its massive storage capacity up to 144TB and advanced features like Docker and virtual machines, making it ideal for creative teams and families with substantial data needs. Unlike the Synology DS925+ with its high data speeds, the DXP4800 Plus emphasizes raw capacity and multi-device support, but it comes with the caveat that drives are not included, which increases initial costs. Network performance depends heavily on your hardware setup, as it supports only wired Ethernet. It’s perfect for those who need extensive storage and cloud flexibility, but less so for users seeking plug-and-play simplicity.

    Pros:
    • Supports up to 144TB of storage capacity
    • Advanced features like Docker containers and virtual machines
    • Compatible across multiple operating systems and devices
    • Secure private cloud with encryption options
    Cons:
    • Drives are not included, adding to initial costs
    • Speed varies with network hardware and setup complexity
    • Limited to wired Ethernet, no Wi-Fi support

    Best for: Small teams, creators, or large families needing extensive storage and remote access features.

    Not ideal for: Single users or those with minimal storage needs who prefer simpler, out-of-the-box solutions.

    • Storage Capacity:Up to 144TB
    • Number of Bays:4
    • Network Ports:10GbE, 10Gbps USB
    • Compatibility:Windows, macOS, Linux, iOS, Android
    • Hard Drive Support:Third-party HDDs/SSDs
    • Warranty:2 years
    Our verdict
    “This NAS best serves users who need large-scale storage with virtualization and remote access capabilities in a wired network environment.”
  3. UGREEN NAS DXP4800 GT 4-Bay for Creators, Tech Enthusiasts, and Office Teams

    UGREEN NAS DXP4800 GT 4-Bay for Creators, Tech Enthusiasts, and Office Teams

    Best for Media Editing and Security with High-Performance Hardware

    View on Amazon

    This NAS distinguishes itself with a powerful AMD Ryzen Embedded R2514 processor, ideal for media editing, multitasking, and surveillance. Compared with the Synology DS925+, the DXP4800 GT offers more raw processing power and supports multiple SSDs and HDDs for flexible storage. Its dual 10GbE ports allow fast, redundant networks, but the setup can be complex for beginners, and drives are not included. The built-in surveillance capabilities make it appealing for security-focused environments, though the non-ECC RAM means it’s less suited for critical data integrity tasks. This setup is best for tech-savvy users who need both performance and versatility.

    Pros:
    • High-performance AMD Ryzen processor supports heavy multitasking
    • Supports multiple SSDs and HDDs for flexible storage options
    • Dual 10GbE ports for fast, redundant connectivity
    • Includes surveillance center and local security features
    Cons:
    • Drives are not included, increasing upfront costs
    • Complex setup may be challenging for beginners
    • Non-ECC RAM limits data integrity for mission-critical applications

    Best for: Media creators, tech enthusiasts, and small office teams requiring high performance and security features.

    Not ideal for: Less experienced users or those seeking simple, plug-and-play solutions for basic storage needs.

    • Processor:AMD Ryzen Embedded R2514, 4 cores, up to 3.70GHz
    • Memory:8GB DDR4 (expandable to 64GB)
    • Storage Capacity:Up to 144TB
    • Networking:Dual 10GbE ports
    • Connectivity:USB 3.2, USB-C, HDMI, SD card slot
    • Additional Features:Surveillance Center, RAID support
    Our verdict
    “This NAS targets power users and creators needing top-tier processing with advanced networking and security features.”
  4. Synology 4-Bay DiskStation DS925+ (Diskless)

    Synology 4-Bay DiskStation DS925+ (Diskless)

    Best for Speed and Versatility in Data Management

    View on Amazon

    The DS925+ stands out with impressive read/write speeds, supporting up to 522/565 MB/s, making it ideal for demanding data transfers and virtualization tasks. Its dual 2.5GbE ports provide fast, redundant network connections, but it’s a diskless model, requiring separate drive purchase, which can add to the initial setup cost. Compared to the UGREEN DXP4800 Plus, the DS925+ offers easier network integration and a more streamlined setup, but with less raw storage capacity out of the box. This device suits users who prioritize speed and reliability, especially in environments where data throughput matters most.

    Pros:
    • Supports up to 522/565 MB/s transfer speeds
    • Dual 2.5GbE ports for fast, redundant network connectivity
    • Versatile features including virtualization and surveillance support
    • Reliable hardware with a 3-year warranty
    Cons:
    • Requires separate purchase of drives, increasing initial costs
    • Setup can be complex for less experienced users
    • No included drives, so total cost depends on drives selected

    Best for: Businesses and power users who need fast data access, virtualization, and reliable network connectivity.

    Not ideal for: Casual users or those with limited budgets who prefer pre-installed drives and simpler setups.

    • Drive Bays:4
    • Network Ports:2 x 2.5GbE
    • Sequential Read Speed:522 MB/s
    • Sequential Write Speed:565 MB/s
    • Warranty:3 years
    Our verdict
    “Ideal for speed-conscious users needing fast network transfer and virtualization support in a flexible NAS platform.”
  5. Synology DS425+ Private Cloud Media Server – 4-Bay Diskless NAS

    Synology DS425+ Private Cloud Media Server - 4-Bay Diskless NAS

    Best for Multi-User Data Sharing and Backup

    View on Amazon

    The DS425+ excels in multi-user environments thanks to its robust data protection and high-speed 2.5GbE networking, making it suitable for home offices or small businesses. While it offers excellent data security and multi-layered protections, its setup can be complex for those unfamiliar with NAS configuration. Like the others, it requires the user to purchase drives separately, and its advanced features might be overkill for simple storage needs. Compared to the DS925+, it’s more compact with a focus on sharing and backup, but less geared toward speed-intensive tasks. This model suits users who prioritize data integrity and multi-user access over raw performance.

    Pros:
    • Supports multi-user access with high-speed 2.5GbE connectivity
    • Robust multi-layered data protections including RAID and snapshots
    • Versatile for file sharing, backups, and surveillance
    • 3-year hardware warranty for peace of mind
    Cons:
    • Requires technical setup, potentially intimidating for beginners
    • No included drives, additional purchase needed
    • May be more complex than necessary for simple storage needs

    Best for: Small businesses or households needing reliable data sharing, backup, and surveillance capabilities.

    Not ideal for: Power users requiring high-speed data transfer or intensive virtualization tasks.

    • Number of Bays:4
    • Connectivity:2.5GbE
    • Warranty:3 years
    • Item Count:1
    • UPC:846504005994
    Our verdict
    “This NAS is well suited for users emphasizing data security and multi-user sharing in a manageable setup.”
  6. UGREEN NAS DXP4800 Pro 4-Bay for IT Professionals, Developers & Power Users

    UGREEN NAS DXP4800 Pro 4-Bay for IT Professionals, Developers & Power Users

    Best Overall for High-Performance Demanding Workflows

    View on Amazon

    The UGREEN NAS DXP4800 Pro stands out for its powerhouse hardware, making it the top choice for IT pros and developers who need more than basic storage. Its Intel Core i3-1315U processor and 8GB DDR5 RAM support demanding tasks like virtualization, Docker, and AI applications, features that the TERRAMASTER F4-425 cannot match in raw power. This model offers impressive scalability with up to 144TB, dual high-speed network ports, and extensive user management. However, its complex setup and larger size can be intimidating for less technical users, and its higher cost reflects its advanced capabilities. Compared to simpler solutions, the DXP4800 Pro prioritizes performance and flexibility at the expense of ease of use. This pick is ideal for businesses or power users who require robust, scalable, and multi-functional storage.

    Pros:
    • Powerful multi-core hardware supporting virtualization and AI tasks
    • Massive storage capacity with flexible RAID options
    • Fast transfer speeds via dual high-speed network ports
    • Supports Docker, VMs, and advanced security features
    Cons:
    • Setup can be complex and require technical expertise
    • Higher price point relative to simpler NAS devices
    • Large physical footprint requiring ample space

    Best for: IT professionals, developers, and advanced power users needing scalable, high-performance storage

    Not ideal for: Home users or small offices seeking simple, budget-friendly NAS solutions

    • Processor:Intel Core i3-1315U (6 Cores, 8 Threads, up to 4.5GHz Turbo)
    • RAM:8GB DDR5 (expandable to 96GB)
    • Graphics:Intel UHD Graphics 13th Gen
    • Network Ports:10GbE + 2.5GbE
    • Storage Capacity:144TB (4x HDD + 2x M.2 SSD)
    • SSD Slots:2 M.2 PCIe 4.0
    Our verdict
    “This NAS is best suited for tech-savvy professionals who need scalable, high-performance storage with advanced features.”
  7. TERRAMASTER F4-425 4-Bay NAS with Intel x86 Quad-Core CPU and 4GB RAM (Diskless)

    TERRAMASTER F4-425 4-Bay NAS with Intel x86 Quad-Core CPU and 4GB RAM (Diskless)

    Best Value for Versatile Media and Power Efficiency

    View on Amazon

    The TERRAMASTER F4-425 offers a compelling balance of performance and affordability, making it suitable for home multimedia enthusiasts and small offices. Its Intel x86 quad-core processor and 4GB RAM enable smooth multitasking and media handling, supporting 4K transcoding that surpasses less capable models like the Yxk Zero1 Pro. Its quiet operation at 21dB makes it ideal for living rooms or home offices. On the downside, it arrives as a diskless system, requiring users to purchase HDDs separately, which adds to the initial setup. The 4-bay configuration limits maximum storage compared to 5- or 6-bay options, possibly restricting future expansion. This NAS makes perfect sense for users seeking reliable multimedia performance without the premium price.

    Pros:
    • Solid quad-core processor handles multitasking efficiently
    • Supports 4K hardware decoding and streaming
    • Quiet operation at 21dB ideal for home environments
    • Easy to install HDDs with tool-free trays
    Cons:
    • No included drives; additional purchase required
    • Limited to 4 bays, restricting future expansion
    • Advanced features may require technical setup

    Best for: Home users or small offices needing 4K media streaming and secure data storage on a budget

    Not ideal for: Power users needing larger capacities or enterprise-level virtualization support

    • Processor:Intel x86 quad-core
    • RAM:4GB
    • Number of Bays:4
    • Maximum Storage:120TB
    • Network Port:2.5GbE
    • HDD Tray:Tool-free Push-Lock
    Our verdict
    “This NAS suits users looking for a budget-friendly, multimedia-capable device for home or small office use.”
  8. Yxk Zero1 Pro 4-Bay NAS for Enthusiasts, Home & Office (Diskless)

    Yxk Zero1 Pro 4-Bay NAS for Enthusiasts, Home & Office (Diskless)

    Best for Enthusiasts and Advanced Home Users

    View on Amazon

    The Yxk Zero1 Pro combines high-end features with flexible customization, making it ideal for enthusiasts and tech-savvy home users. Its Intel N100 processor paired with 8GB DDR4 RAM offers a strong foundation for demanding tasks like 4K streaming, AI-powered photo management, and Docker containers. The support for up to 144TB of storage and full compatibility with third-party OSes like TrueNAS or Unraid sets it apart from more locked-down systems like the Synology DS423. Its dual 2.5GbE ports and 4K HDMI output enhance its multimedia and remote management capabilities. The main tradeoff is that drives are sold separately, and installing third-party OSes requires some technical knowledge. This model is perfect for users who want maximum flexibility and power for customization.

    Pros:
    • Supports large storage up to 144TB and multiple drive types
    • Full Docker and third-party OS support for customization
    • Strong hardware for demanding tasks like AI and 4K streaming
    • Includes HDMI for direct media output
    Cons:
    • Requires purchasing drives separately
    • Installation of third-party OS may be complex for some users
    • No pre-installed drives; setup can be involved

    Best for: Enthusiasts, hobbyists, and advanced home or small office users comfortable with DIY setup

    Not ideal for: Casual users or those seeking plug-and-play simplicity without additional setup

    • Processor:Intel N100
    • RAM:8GB DDR4
    • Drive Bays:4 SATA 3.0
    • Maximum Storage:144TB
    • Network Ports:2 x 2.5GbE
    • Cooling System:Dual-fan with aluminum heatsink
    Our verdict
    “This NAS excels for tech enthusiasts who want maximum flexibility and are comfortable with manual setup and customization.”
  9. Synology DS423 4-Bay Diskless NAS for Backup, File Sharing, and Surveillance

    Synology DS423 4-Bay Diskless NAS for Backup, File Sharing, and Surveillance

    Best for Security and Data Backup

    View on Amazon

    The Synology DS423 offers a balanced package for users prioritizing data security, backup, and surveillance. Its private cloud features and support for up to 30 IP cameras make it a strong choice for small businesses and security-conscious homes. While its diskless configuration keeps initial costs lower, it requires users to purchase drives separately. Compared to the QNAP TS-464-8G-US, it emphasizes security and ease of use, but lacks hardware acceleration for media transcoding. Its straightforward setup and focus on data protection make it an excellent choice for users seeking reliable, secure storage with surveillance capabilities.

    Pros:
    • Robust security with ransomware protection and snapshots
    • Supports up to 30 IP cameras for surveillance
    • Private cloud access simplifies remote file sharing
    • Two-year warranty adds peace of mind
    Cons:
    • Camera licenses are sold separately
    • Requires technical setup for surveillance features
    • No drives included, increasing initial cost

    Best for: Small businesses and home users needing secure backup and surveillance support

    Not ideal for: Power users requiring advanced multimedia or virtualization features

    • Number of Bays:4
    • Storage Type:Diskless
    • Supports IP Cameras:Up to 30
    • Warranty:2 years
    • Features:File sharing, data backup, video surveillance
    Our verdict
    “This NAS is well-suited for users focused on secure backup, file sharing, and surveillance in a reliable, easy-to-manage system.”
  10. QNAP TS-464-8G-US 4-Bay Desktop NAS

    QNAP TS-464-8G-US 4-Bay Desktop NAS

    Best for Centralized Storage with Fast Transfer

    View on Amazon

    The QNAP TS-464-8G-US provides a versatile option for users seeking fast, centralized storage for media collections. Its quad-core Intel N5105/N5095 processor and 8GB DDR4 RAM handle multi-user access smoothly, while dual 2.5GbE ports deliver quick network speeds. The inclusion of M.2 PCIe SSD slots allows for cache acceleration, significantly boosting performance for demanding workflows compared to basic NAS devices like the Asustor Drivestor 4. USB 3.2 ports facilitate rapid data transfers, making this a solid choice for media libraries. However, the lack of detailed pricing and limited pre-installed features mean it’s best for users comfortable with technical setup. This NAS is ideal for those looking for fast, reliable, centralized storage with upgradeability.

    Pros:
    • Fast dual 2.5GbE network ports support quick data transfer
    • Supports SSD cache acceleration for improved performance
    • Multiple USB 3.2 ports for flexible connectivity
    • Expandable with M.2 SSD slots for caching
    Cons:
    • Price info not specified, which may affect decision making
    • Requires technical knowledge for setup and configuration
    • Limited pre-installed features for non-technical users

    Best for: Power users and small teams needing quick, expandable storage for media and backups

    Not ideal for: Entry-level users or those wanting a plug-and-play experience without setup complexity

    • Processor:Intel N5105/N5095 quad-core
    • RAM:8GB DDR4
    • Number of Bays:4
    • Network Ports:Dual 2.5GbE
    • SSD Slots:2 M.2 PCIe Gen3x2
    • USB Ports:Multiple USB 3.2 Gen 2
    Our verdict
    “This NAS makes the most sense for users who need fast, expandable storage and are comfortable with initial setup.”
  11. Asustor Drivestor 4 Pro Gen2 AS3304T v2 4-Bay NAS

    Asustor Drivestor 4 Pro Gen2 AS3304T v2 4-Bay NAS

    Best Value for High-Speed Home and Small Business Use

Factors to Consider When Choosing 4 Bay Nas

When selecting a 4 bay NAS, it’s essential to consider several factors that influence usability, performance, and future-proofing. Understanding these will help you avoid common pitfalls and ensure your investment matches your needs. The right NAS can streamline backups, media streaming, or business workflows, but a mismatch can lead to frustration or additional costs down the line.

Performance and Hardware Specifications

The processor and RAM determine how smoothly your NAS handles multitasking, media transcoding, or virtualization. A faster CPU and more RAM support complex workloads and future upgrades. However, high-end specs usually come with a higher price tag, so consider your actual usage to avoid overpaying for features you won’t need.

Network Connectivity and Speed

Look for models with at least 2.5GbE ports if you plan to transfer large files regularly or run media servers. Some options include multiple Ethernet ports for link aggregation, boosting network throughput. Cheaper models might only have gigabit ports, which can bottleneck your data transfers if you’re working with large files or multiple users.

Ease of Use and Management

User-friendly interfaces and setup wizards make a big difference, especially for beginners. Brands like Synology are known for intuitive management software, while more advanced users might prefer open-source options or more customizable firmware. Consider the learning curve involved and whether the manufacturer offers good customer support.

Expandability and Future-Proofing

Some NAS units support additional RAM or have multiple USB ports for attaching external drives, which can extend their lifespan. Think about your potential future needs — if you might add more drives or need higher network speeds later, choose a model that supports upgrades without replacing the entire device.

Price and Total Cost of Ownership

Initial purchase price is only part of the total cost. Consider the cost of hard drives, potential extensions, and power consumption. Cheaper models might save money upfront but could become limiting or less reliable over time. Conversely, investing in a higher-end model might reduce future upgrades and maintenance costs.

Frequently Asked Questions

Is it better to buy a diskless NAS or one with drives pre-installed?

Opting for a diskless NAS offers flexibility to choose your own hard drives, which can be cost-effective if you already own compatible drives or want specific brands. It allows for tailored storage configurations and potentially better performance. However, pre-installed models provide convenience and are ready to use immediately, which can be appealing for less technical users. Consider your comfort with installing drives and your long-term storage plans when making this choice.

How important is the CPU in a 4 bay NAS for typical home use?

The CPU impacts how efficiently your NAS handles multitasking, media transcoding, or running additional services. For basic tasks like file sharing and backups, a modest dual-core CPU suffices. If you plan to run media servers that transcode videos or virtual machines, a more powerful processor becomes valuable. For most home users, balancing CPU power with budget is key to avoiding overpaying for unnecessary performance.

Can I add more drives later if I start with a 4 bay NAS?

Most 4 bay NAS units do not support adding more drives beyond their initial capacity, as they are designed with fixed bays. However, some models support external drives via USB or have expansion options for attaching additional storage. Planning your storage needs for the future is wise, and choosing a model with external expandability can save money and hassle later.

What features should I prioritize if I want a NAS primarily for media streaming?

Look for models with hardware transcoding capabilities, especially if you stream to multiple devices or use high-resolution media. A fast CPU, sufficient RAM, and multiple network ports for higher throughput are beneficial. User-friendly media management apps and strong support for popular streaming protocols also enhance the experience. While storage capacity is important, performance features often make a bigger difference for streaming quality.

Is a higher RAM capacity necessary for personal use?

For basic file sharing, backups, and media streaming, 2GB to 4GB of RAM is usually enough. More RAM becomes important if you run multiple applications, virtual machines, or surveillance systems on your NAS. Higher RAM supports smoother multitasking and future upgrades, but for most personal use cases, investing in a model with 4GB RAM strikes a good balance between performance and cost.

Conclusion

For general home users or small offices seeking a reliable, easy-to-manage system, the Synology DiskStation DS925+ offers a balanced mix of performance and user-friendliness. Those prioritizing budget and expandability might prefer the QNAP TS-464-8G-US for its features at a lower price. Power users or professionals needing maximum performance should consider the TERRAMASTER F4-425 with its robust hardware. Beginners aiming for a straightforward setup will find the Asustor Drivestor 4 Gen 2 to be a friendly entry point. Overall, your choice depends on your specific needs, budget, and future plans for storage expansion.
