    Best Overall for Power Users and Small Offices

    View on Amazon
    The Synology DS925+ stands out for its impressive data transfer speeds, reaching up to 565 MB/s, making it ideal for users who need quick access to large files.

    UGREEN NAS DH4300 Plus 4-Bay Home Storage for Beginners and Remote Workers

    Best for Ease of Use and Home Media Storage

    View on Amazon
    The UGREEN NAS DH4300 Plus offers a straightforward, user-friendly experience, making it ideal for home users and remote workers who want reliable storage without complex configurations. Its support for automatic photo backups, AI photo albums, and 4K HDMI output makes it ideal for media enthusiasts, especially when compared with the Synology DS423, which emphasizes security and surveillance features more suited for small businesses. However, it lacks Wi-Fi support, limiting flexibility for wireless environments, and requires users to purchase drives separately. This pick is perfect for those who prioritize simplicity and media features over enterprise-level security or virtualization.
    Pros:
    • Easy to set up with clear instructions
    • Supports automatic photo backup and AI albums

    View on Amazon
    The Synology DS423 is a versatile option that emphasizes security, with private cloud access, ransomware resistance, and support for up to 30 IP cameras, making it suitable for small business or home security setups. Compared to the UGREEN DXP4800 GT, which offers high-performance multitasking, the DS423 focuses more on data protection and remote access. Its two-year warranty and comprehensive backup options make it a solid choice for users prioritizing security, although the need to purchase drives separately and the requirement for technical knowledge to configure surveillance features are notable tradeoffs. It’s best for those who want robust data protection without enterprise-level complexity.
    Pros:
    • Secure private cloud access from anywhere
    • Supports up to 30 IP cameras for surveillance
    • Strong ransomware protection and snapshot backups
    Cons:
    • Camera licenses sold separately

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

    Best for High Performance and Creative Workflows

    View on Amazon
    The UGREEN DXP4800 GT is engineered for demanding environments, featuring an AMD Ryzen Embedded R2514 processor capable of multitasking, media encoding, and running multiple virtual machines. Its expandable storage up to 144TB and dual 10GbE ports support rapid data transfer and large workloads—ideal for small offices, media creation, or intensive data tasks, especially compared to the DS425+ which offers similar features but with a less powerful CPU. The setup complexity and higher cost, combined with non-ECC RAM, mean this NAS suits experienced users comfortable with detailed configuration. It’s a clear choice for those who need enterprise-like performance at a smaller scale.
    Pros:
    • Powerful AMD Ryzen embedded CPU for multitasking
    • Supports up to 144TB storage with NVMe and SSD support
    • Dual 10GbE ports for ultra-fast data transfer
    Cons:

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

    Best for Enterprise-Grade Performance and Virtualization

    View on Amazon
    The UGREEN DXP4800 Pro delivers serious processing power with an Intel processor, supporting demanding workflows like virtualization, AI, and large-scale data management. Its capacity for 144TB, support for Docker containers, and virtual machines make it stand out among 4-bay NAS options, especially when compared with the DXP4800 GT, which focuses more on media and creative work. This model’s enterprise features, including data encryption and multi-zone cooling, come with a steeper learning curve and higher cost, but they provide the reliability professional users require. If your work involves complex applications or virtualization, this NAS offers the necessary power, albeit at the expense of simplicity.
    Pros:

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

    Best Overall for Versatile High-Performance Small-Scale Storage

    View on Amazon

    This model stands out for its massive storage capacity of up to 144TB and fast data transfer speeds thanks to 10GbE and USB 3.2 ports. Unlike the Synology DS423, which is limited to 4 bays and smaller capacity, the UGREEN offers more scalability for small teams or creators needing extensive space. It supports Docker, virtual machines, and AI photo organization, making it suitable for technically inclined users. The primary tradeoff is that drives are not included, and it relies solely on wired Ethernet—no Wi-Fi support—so setup complexity can be higher for less technical users. Transfer speeds may vary depending on network setup, which can impact productivity in real-world use. This pick makes the most sense for those needing large storage and advanced features in a wired environment.

    Pros:
    • Massive storage capacity up to 144TB
    • Fast transfer speeds with 10GbE and USB ports
    • Supports Docker and virtual machines for advanced workflows
    • Secure private cloud with encryption and permission controls
    Cons:
    • Hard drives are not included and must be purchased separately
    • Supports wired Ethernet only, no Wi-Fi
    • Transfer speeds depend heavily on network setup

    Best for: Small teams, content creators, or families with high storage needs and technical expertise

    Not ideal for: Users seeking Wi-Fi connectivity or a plug-and-play experience with included drives

    • Storage Capacity:Up to 144TB
    • Number of Bays:4
    • Connectivity:10GbE network port, 10Gbps USB ports
    • Compatibility:Windows, macOS, Linux, iOS, Android, Google services
    • Hard Drives Included:No
    • Warranty:2 years
    Our verdict
    “A robust choice for technically skilled users demanding large capacity and advanced features in a wired setup.”
  7. Synology 2-Bay DiskStation DS223j (Diskless)

    Synology 2-Bay DiskStation DS223j (Diskless)

    Best for Basic Private Cloud and Home Security

    View on Amazon

    The Synology DS223j is ideal for users prioritizing ease of access and security over expandability, especially compared with larger-capacity options like the TERRAMASTER F4-425. Its 2-bay design means less total storage, but it simplifies setup and management for home users. The device excels at secure file sharing, automated backups, and even home security integration, supported by Synology’s intuitive DiskStation Manager software. The main tradeoff is its limited maximum capacity and fewer bays, which restrict future expansion. It’s best suited for individuals or small families who want reliable, multi-platform private cloud storage without the complexity of larger systems. However, users needing extensive storage or enterprise features should consider higher-capacity models.

    Pros:
    • Secure private cloud with multi-platform access
    • Automated backups for multiple devices
    • Supports home security with IP camera monitoring
    • Reliable hardware backed by 2-year warranty
    Cons:
    • Requires additional disks for storage capacity
    • Limited to 2 bays, less room for future expansion
    • No included drives, additional cost

    Best for: Home users and small families seeking secure, easy-to-manage private cloud storage

    Not ideal for: Environments requiring large-scale storage or high levels of expandability

    • Storage Bays:2
    • Diskless:Yes
    • Warranty:2 years
    • Features:Private cloud, file sharing, automated backup, home security
    Our verdict
    “A straightforward, secure NAS ideal for home users prioritizing ease and security over capacity.”
  8. Asustor Drivestor 4 Gen 2 AS1204T 4-Bay NAS

    Asustor Drivestor 4 Gen 2 AS1204T 4-Bay NAS

    Best for Home and Small Office with Media Transcoding

    View on Amazon

    Compared with the Synology DS425+ which offers higher-end hardware, the Asustor Drivestor 4 Gen 2 balances affordability with solid performance, thanks to its 1.7GHz quad-core processor and 2.5GbE ports. Its support for 4K media streaming and multiple RAID options makes it well-suited for multimedia-heavy environments, especially for those who want to create a personal cloud without overpaying for premium hardware. However, its 1GB RAM might limit performance during intensive multitasking, and it does not come with drives, which could be a drawback for first-time buyers. It’s an excellent choice for users who need versatile media and file sharing capabilities on a budget but are comfortable with basic setup procedures. Those requiring extensive multitasking or enterprise features should look elsewhere.

    Pros:
    • Fast 2.5GbE network for quick file transfers
    • Supports multiple RAID configurations for redundancy
    • 4K media streaming capabilities
    • Creates a private cloud for remote access
    Cons:
    • Limited 1GB RAM may restrict multitasking
    • No included hard drives, diskless by default
    • Basic warranty period without extended options

    Best for: Home users and small offices focused on media streaming and RAID flexibility

    Not ideal for: Power users needing high RAM for heavy multitasking or enterprise environments

    • Processor:Realtek RTD1619B 1.7GHz Quad-Core
    • RAM:1GB DDR4
    • Network:2.5GbE Port
    • Number of Bays:4
    • Supported RAID:0/1/5/6/10
    • USB Ports:3
    • Hard Drive Compatibility:2.5 inches
    Our verdict
    “A capable, budget-friendly NAS for multimedia enthusiasts and small offices needing flexible RAID options.”
  9. Synology DS425+ Private Cloud Media Server – 4-Bay Diskless NAS

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

    Best for Multi-User, High-Speed Data Sharing & Surveillance

    View on Amazon

    While the Synology DS425+ shares the same form factor as the DS223j, it targets users needing more robust performance and multi-user handling, thanks to its 2.5GbE ports and more powerful hardware. Compared to the TERRAMASTER F4-425, which offers higher raw capacity and hardware, the DS425+ emphasizes security, software versatility, and easy management via Synology DiskStation Manager. Its three-year warranty adds reassurance for business or demanding home use, but setup and management can be more complex, especially for less experienced users. It’s suited for small businesses or tech-savvy households that need reliable multi-user access, backup, and surveillance integration. Heavy multitasking or large data loads might stretch its hardware, but overall, it provides a well-rounded platform for shared data use.

    Pros:
    • High-speed 2.5GbE network connectivity

    • Warranty:3 Years
    • Features:Multi-user, backup, surveillance
    Our verdict
    “A solid, multi-purpose NAS for users comfortable with software management and multi-user environments.”
  10. TERRAMASTER F4-425 4-Bay NAS Intel x86 Quad-Core CPU 4GB RAM (Diskless)

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

    Best for Power Users with High Performance and Future Expansion

    View on Amazon

    The TERRAMASTER F4-425 is designed for users demanding raw performance and expandability, with its Intel x86 quad-core processor and 4GB RAM. It surpasses the Synology DS425+ in raw hardware power, supporting 4K hardware decoding and RAID levels suitable for data redundancy and performance. Compared to the UGREEN DXP4800, which is more feature-rich but less performance-focused, the F4-425 emphasizes stability and reliability for heavy workloads. Its 2.5GbE ports enable fast network transfers, and its tool-free drive installation simplifies setup. However, the device is diskless, requiring users to purchase drives separately, and its software ecosystem is less intuitive than Synology’s. This NAS is best for home multimedia or small office users who prioritize hardware performance and upgradeability over out-of-the-box features.

    Pros:
    • Powerful Intel x86 quad-core processor
    • Supports 4K hardware decoding
    • 4GB RAM for multitasking

    • Less user-friendly software ecosystem

    Best for: Power users needing high-performance hardware and expandability for multimedia or data security

    Not ideal for: Casual users or those seeking a ready-to-use, simple NAS setup

    • Processor:Intel x86 quad-core
    • RAM:4GB
    • Storage Capacity:up to 120TB
    • Network Ports:2.5GbE
    • Number of Bays:4
    • Supported RAID:TRAID / TRAID+
    Our verdict
    “A high-performance NAS tailored for tech-savvy users who need reliable, expandable hardware for demanding tasks.”
  11. Synology DS225+ Private Cloud Media Server – 2-Bay Diskless NAS with Intel CPU

    Synology DS225+ Private Cloud Media Server - 2-Bay Diskless NAS with Intel CPU

    Best for Compact Home Use and Media Streaming

    View on Amazon

    The Synology DS225+ stands out for its compact design and powerful media capabilities, making it an excellent choice for users who want private cloud access and 4K streaming in a smaller footprint. Compared with the Synology DS423, which offers more bays, the DS225+ sacrifices expandability but compensates with a faster CPU and AI-driven surveillance features. Its diskless setup means you must supply drives, which adds initial cost, and its 2-bay configuration limits RAID options and storage capacity, making it less suitable for users needing extensive data expansion. The device’s support for up to 30 IP cameras and automated backups makes it ideal for small home or office environments prioritizing media and security. However, beginners may find the setup process challenging without prior NAS experience.

    Pros:
    • Supports 4K media streaming and private cloud storage
    • Automated backups with multi-layered data protection
    • Supports AI surveillance and remote monitoring
    • Reliable 3-year warranty
    Cons:
    • Requires separate drives, adding to initial cost
    • Limited to 2 bays, restricting storage capacity and RAID flexibility
    • Setup can be complex for users unfamiliar with NAS configurations

    Best for: Home users or small businesses needing a compact, media-focused NAS with surveillance features.

    Not ideal for: Users requiring high storage capacity or advanced data redundancy—its 2-bay design limits expansion and RAID options.

    • Storage Bays:2-Bay
    • CPU:Intel
    • Transfer Speed:282 MB/s
    • Warranty:3 Years
    • Supports IP Cameras:Up to 30
    • Diskless:Yes
    Our verdict
    “This NAS is best suited for users who prioritize media streaming, surveillance, and a compact footprint over large storage capacity.”

Factors to Consider When Choosing Network Attached Storage 4 Bay

Choosing the right 4-bay NAS involves understanding a few key factors that influence performance, usability, and long-term investment. Beyond just comparing specs, it’s important to consider how each feature aligns with your intended use, whether for media streaming, backups, or professional workloads. Making the wrong choice can lead to underwhelming performance or unnecessary expenses. This guide highlights the most important considerations to help you make an informed decision and avoid common pitfalls.

Performance and Hardware

The CPU and RAM are primary indicators of how well a NAS can handle multitasking, large data transfers, or demanding apps. For light use, such as backups or media streaming, a modest processor and 2-4GB of RAM might suffice. Power users running virtual machines, heavy media editing, or multiple simultaneous connections should look for higher-spec models with faster CPUs and at least 8GB of RAM. Keep in mind that hardware can be upgraded on some models, providing future-proofing without immediate extra costs.

Software Ecosystem and User Experience

A user-friendly interface and robust software ecosystem are essential, especially for beginners. Brands like Synology excel here with their intuitive DiskStation Manager, which simplifies setup and ongoing management. More technical users might prefer open-source or customizable options, but these often require more technical knowledge. Reliable software updates and security features are vital to protect your data over time. Be wary of models with limited app support or complex interfaces that can hinder productivity.

Expandability and Connectivity

While 4 bays suffice for most home and small business needs, consider how much storage you might need to add later. Some models support expansion units or have features like multiple Ethernet ports for link aggregation. USB ports for direct backups or peripherals can also enhance functionality. Think about your future growth plans—choosing a device with extra expansion options now can save time and money later, especially if your data needs increase.

Price and Long-Term Value

Higher initial investments often translate into more durable hardware, better performance, and longer software support. Cheaper models might tempt budget-conscious buyers but can come with compromises such as slower processors, limited RAM, or weaker build quality. Consider the total cost of ownership, including potential drive upgrades, extended warranties, and power consumption. Sometimes, spending more upfront guarantees fewer headaches and better reliability over the years.

Drive Compatibility and Setup

Most NAS devices are diskless, giving you flexibility in choosing drives, but compatibility is key. Look for models that support a wide range of HDDs and SSDs to avoid setup issues. Consider whether the NAS supports RAID configurations—essential for data redundancy and protection. Ease of setup varies; some units offer quick-setup wizards, while others require manual configuration, which might be challenging for less tech-savvy users. Proper planning here helps prevent data loss and setup frustration.

Frequently Asked Questions

Can I upgrade the drives in a 4-bay NAS after purchase?

Yes, most 4-bay NAS models are diskless or come with empty bays, allowing you to choose and upgrade drives over time. Compatibility with standard HDDs and SSDs ensures flexibility in expanding storage or improving performance. When upgrading, it’s important to follow the manufacturer’s guidelines to avoid data loss or hardware issues. Planning for future expansion at the time of purchase can simplify upgrades later on, especially if you anticipate growing storage needs.

Is a higher RAM capacity necessary for my home media server?

For basic media streaming, 2-4GB of RAM is often sufficient. However, if you plan to run multiple streams, transcode high-resolution videos, or use the NAS for other demanding tasks, increasing the RAM to 8GB or more can significantly improve performance. Higher RAM also helps if you want to run additional apps or virtual machines on your NAS. Balancing your budget against your performance needs will guide the right choice.

What should I look for in the software features of a NAS?

Reliable, user-friendly software is key to managing your data efficiently. Look for intuitive interfaces, automatic backups, and security features like encryption and malware protection. Support for common media apps, remote access, and cloud integration adds convenience. A strong app ecosystem can extend your NAS’s capabilities, whether for media management, surveillance, or collaboration tools. Compatibility with your existing devices and ease of updates are also important considerations.

Is it worth investing in a premium NAS with more features?

Premium models often provide faster processors, more RAM, and advanced features like dual Ethernet ports or hardware encryption. If your workload involves heavy data processing, multiple users, or professional use, these features can justify the higher price. For casual home use, a mid-range or budget model generally offers sufficient performance. Evaluate your current and future needs carefully to decide if the added investment aligns with your use case.

How important is warranty and customer support when choosing a NAS?

Warranty coverage and responsive customer support can significantly impact your experience, especially if technical issues arise. Reliable brands typically offer longer warranties and comprehensive support options, reducing downtime or repair costs. Good support can also help with setup, troubleshooting, and firmware updates, which are vital for maintaining security and performance. Prioritizing these aspects can provide peace of mind and protect your investment over the long term.

Conclusion

For most home users and small offices, the Synology DS925+ offers a well-rounded experience with excellent software and future-proofing, making it the best overall pick. Budget-conscious buyers or those new to NAS will find the UGREEN NAS DH4300 Plus straightforward and affordable, ideal for beginners. Power users and IT professionals should consider the TERRAMASTER F4-425 for its robust hardware and expandability, providing a solid foundation for demanding tasks. Ultimately, your choice depends on your technical comfort level, performance needs, and budget, but these recommendations cover the most common scenarios effectively.
