More Details on Our Top Picks

  1. 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 Overall for Versatility and Security

    View on Amazon

    The Synology DS423 stands out for its comprehensive approach to home and small business needs, combining secure private cloud access, flexible data backup options, and support for up to 30 IP cameras. Unlike the Ugreen DXP4800 Plus, which excels in raw storage capacity, the DS423 offers a more intuitive setup for surveillance and data protection, though at an extra cost for camera licenses. Its hardware reliability and 2-year warranty add peace of mind, but the need to purchase drives separately and the technical setup for surveillance might challenge less tech-savvy users. This model is ideal for users seeking a secure, all-in-one NAS that balances backup, file sharing, and security features without high complexity.

    Pros:
    • Secure private cloud access from anywhere
    • Supports comprehensive data backup with snapshots
    • Versatile video surveillance for up to 30 cameras
    • Reliable hardware with 2-year warranty
    Cons:
    • Camera license must be purchased separately
    • No included drives, additional cost for storage
    • Requires technical setup for surveillance system

    Best for: Home users or small offices needing secure file sharing, backup, and surveillance in a single device

    Not ideal for: Users seeking plug-and-play simplicity or pre-installed drives, due to setup complexity and additional costs

    • Number of Bays:4
    • Type:Diskless NAS
    • Features:Private cloud, data backup, video surveillance, file server, ransomware protection
    • Warranty:2 years
    Our verdict
    “This NAS is best for users who want a flexible, secure multi-purpose device with robust surveillance and backup features, and are prepared for initial setup.”
  2. Synology DS425+ 4-Bay Diskless NAS Private Cloud Media Server

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

    Best for Business and Media Professionals

    View on Amazon

    The Synology DS425+ is designed with productivity in mind, offering high-speed data transfer (278 MB/s) and support for over 10 users, making it suitable for small teams or media-heavy environments. Compared with the Asustor Drivestor 4 Pro, which emphasizes ease of setup, the DS425+ leans toward enterprise features and performance, with a longer 3-year warranty and support for professional surveillance with 30 cameras. Its complex setup and need for additional disks make it less appealing for less technical users or those seeking a quick-start solution. This model makes the most sense for small businesses or media creators prioritizing speed, multi-user support, and data security.

    Pros:
    • High-speed data transfer of 278 MB/s
    • Supports multiple users and professional surveillance
    • Multi-layered data protection with RAID, backups, and snapshots
    • Includes 3-year warranty and enterprise support
    Cons:
    • Requires additional disks for storage
    • Complex setup for non-technical users
    • Price not specified, potentially higher cost for premium features

    Best for: Small teams or creative professionals requiring fast, multi-user access and robust surveillance compatibility

    Not ideal for: Home users or beginners who prefer a simple, all-in-one plug-and-play setup due to its complexity

    • Number of Bays:4
    • Type:Diskless NAS
    • Speed:278 MB/s
    • User Support:10+ users
    • Surveillance Support:Supports 30 IP cameras
    • Warranty:3 years
    Our verdict
    “Ideal for professionals needing fast, reliable network storage with strong security and surveillance features, provided they can handle setup complexity.”
  3. Asustor Drivestor 4 Pro Gen2 AS3304T v2 4-Bay NAS

    Asustor Drivestor 4 Pro Gen2 AS3304T v2 4-Bay NAS

    Best for Home and Small Office with Speed Needs

    View on Amazon

    The Asustor Drivestor 4 Pro Gen2 AS3304T v2 offers high-speed 2.5GbE connectivity and flexible RAID options, making it a strong choice for users seeking quick local data transfers and easy drive installation. It outperforms models like the Terramaster F4-425 on network speed, but with only 2GB RAM, its multitasking capacity could fall short for heavy workloads. Its straightforward, tool-free drive setup appeals to non-technical users, yet the basic feature set may limit its appeal for those with advanced enterprise needs. It strikes a balance for small offices or home users prioritizing speed and simplicity over extensive enterprise features.

    Pros:
    • High-speed 2.5GbE network connectivity
    • Flexible RAID configurations for data protection
    • Easy tool-free drive installation
    • Supports private cloud for remote access
    Cons:

    • No included drives, additional purchase needed
    • Basic features may not suit advanced enterprise needs

    Best for: Home users or small offices needing fast local network performance and easy setup

    Not ideal for: Power users or enterprise environments requiring extensive RAM and advanced security options

    • Processor:Realtek quad-core
    • RAM:2GB DDR4
    • Network Connectivity:2.5GbE Ethernet
    • Number of Bays:4
    • Supported RAID:0, 1, 5, 6, JBOD
    • Supported OS:Linux
    Our verdict
    “Best suited for users who want fast, local network storage with simple setup, but not for heavy multitasking or enterprise-level demands.”
  4. UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams

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

    Best for Large Storage Needs and Media Creation

    View on Amazon

    The UGREEN DXP4800 Plus impresses with its massive storage capacity up to 144TB and rapid data transfer capabilities via 10GbE and multiple USB 3.2 ports. It stands out for creative professionals or small teams needing extensive storage and advanced features like Docker containers and virtual machines. Unlike the UGREEN NAS DXP4800 Pro, which is geared toward power users, the Plus version emphasizes capacity and connectivity. However, it requires separate hard drives and relies on wired Ethernet, limiting flexibility for wireless environments. This pick makes sense for users demanding large-scale storage and media processing capabilities, willing to invest in high-performance hardware.

    Pros:
    • Massive storage capacity up to 144TB
    • Fast transfer speeds with 10GbE and USB ports
    • Supports advanced features like Docker and VMs
    • Secure private cloud with encryption
    Cons:
    • Hard drives are purchased separately
    • Speed depends on network hardware and setup
    • Wired Ethernet only, no built-in Wi-Fi

    Best for: Content creators, small teams, or families with large media libraries needing vast storage and fast transfer speeds

    Not ideal for: Users seeking a Wi-Fi-enabled NAS or those with limited budgets, since drives are not included and setup may require network expertise

    • Storage Capacity:Up to 144TB
    • Number of Bays:4
    • Connectivity:10GbE network port, 10Gbps USB ports
    • Compatibility:Windows, macOS, Linux, iOS, Android
    • Hard Drives Included:No
    • Warranty:2 years
    Our verdict
    “Excellent for media professionals or large households needing extensive storage and high-speed data handling, provided they can manage setup and additional drive costs.”
  5. 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 for Demanding Workflows and Virtualization

    View on Amazon

    The UGREEN NAS DXP4800 Pro is tailored for power users and IT professionals, featuring an Intel Core i3-1315U CPU, up to 96GB RAM, and support for Docker and virtual machines. Its robust hardware supports heavy multitasking and complex workflows, outperforming models like the Terramaster F4-425 in processing power and expandability. The support for 144TB storage, SSD slots, and advanced security makes it suitable for demanding enterprise environments, yet its complex setup and larger footprint may deter casual users. This device is best suited for those requiring enterprise-grade performance and flexibility, capable of handling virtualization and extensive data security.

    Pros:
    • High-performance hardware with Intel Core i3
    • Supports virtualization and Docker containers
    • Massive storage capacity and RAM expansion
    • Advanced security and privacy features
    Cons:
    • Setup can be complex and technical
    • Large form factor not suited for small spaces
    • Premium hardware comes at a higher cost

    • SSD Slots:2 M.2 PCIe 4.0
    • User Accounts:Supports up to 2048
    Our verdict
    “Best for demanding workflows that require high processing power, virtualization support, and extensive security, assuming the user can handle complex setup.”
  6. TERRAMASTER F4-425 4-Bay NAS with Intel x86 Quad-Core CPU and 4GB RAM

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

    Best Overall Performance for Power Users

    View on Amazon

    The TERRAMASTER F4-425 stands out for its powerful Intel x86 quad-core processor and 4GB RAM, making it well-suited for demanding tasks like 4K transcoding and multi-user access. Compared to the Asustor Drivestor 4 Gen 2 with a less robust processor, the F4-425 delivers faster performance for media-heavy workflows. Its quiet operation at 21dB allows it to blend into home environments without disturbance. However, being diskless means you need to purchase drives separately, and its maximum storage capacity of 120TB, while substantial, is limited for very large data farms. Setup requires some technical knowledge, especially for optimizing performance and security. Overall, this NAS is ideal for users needing a reliable, high-performance home media and data server but who are comfortable with initial configuration.

    Pros:
    • Powerful quad-core Intel x86 processor ensures fast performance
    • Supports 4K media transcoding and multi-user access
    • Quiet operation at 21dB suitable for home environments
    • Easy HDD installation with tool-free trays
    Cons:
    • No hard drives included; additional purchase needed
    • Limited maximum storage of 120TB for very large data needs

    Best for: Power users and tech-savvy home users needing high performance and media transcoding.

    Not ideal for: Beginners or those seeking an all-in-one solution with included drives and simple setup.

    • Processor:Intel x86 quad-core
    • RAM:4GB
    • Number of Bays:4
    • Max Storage:120TB
    • Network Interface:2.5GbE
    • Noise Level:21dB
    Our verdict
    “This NAS is best for experienced users who prioritize performance and media capabilities without fussing over included drives.”
  7. UGREEN NAS DXP4800 GT 4-Bay Network Storage for Creators and Office Teams

    UGREEN NAS DXP4800 GT 4-Bay Network Storage for Creators and Office Teams

    Best for High-Performance Multitasking and Media Management

    View on Amazon

    The UGREEN NAS DXP4800 GT offers a robust AMD Ryzen Embedded R2514 processor and expandable RAM up to 64GB, making it ideal for creators and small offices that need to run multiple demanding applications simultaneously. Its dual 10GbE ports with link aggregation deliver blazing-fast network speeds, surpassing the 2.5GbE in the Asustor Drivestor 4. The multiple drive bays and NVMe support enable extensive storage customization, though drives are not included, requiring additional investment. Its built-in surveillance and UGS Pro ecosystem expand its utility beyond simple file sharing. Setup can be complex, especially when configuring advanced features like Docker containers or surveillance, so it’s best suited to users with some technical knowledge. If high performance and expandability are priorities, this NAS is a solid choice.

    Pros:
    • High-performance multitasking with up to 64GB RAM support
    • Dual 10GbE ports with link aggregation for maximum network throughput
    • Supports extensive storage expansion and NVMe SSDs
    • Built-in surveillance features and UGS Pro ecosystem
    Cons:
    • Drives are not included; additional purchase required
    • Setup and configuration may be complex for less experienced users

    Best for: Creators, small teams, and power users needing advanced multitasking, fast networking, and extensive storage options.

    • Storage Capacity:Up to 144TB
    • Network:Dual 10GbE
    • Drive Bays:4 SATA + 2 NVMe
    • Additional Features:Built-in surveillance, UGS ecosystem
    Our verdict
    “This NAS caters best to prosumers and small offices that need speed, expandability, and multimedia management in one package.”
  8. 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 Private Cloud and Reliable Data Backup

    View on Amazon

    The Synology DS225+ is tailored for users seeking a dependable private cloud with media streaming, offering a solid Intel CPU and support for 4K media. Its two bays limit total storage capacity but ensure simplicity and reliability, making it an attractive choice over larger options like the Synology DS423. The NAS excels at automated backups and surveillance with AI detection, providing strong data protection, though its diskless design means additional drives are necessary. Its user-friendly interface is suitable for those comfortable with network setup but might challenge absolute beginners for advanced features. Overall, this model balances ease of use with robust cloud and media capabilities, ideal for small households or remote workers.

    Pros:
    • Supports 4K media streaming and private cloud creation
    • Automated backups and multi-layer data protection
    • Surveillance support with AI detection
    • Reliable 3-year warranty
    Cons:

    • Limited storage capacity with only two bays

    Best for: Small households and remote workers needing reliable cloud storage, backups, and security monitoring.

    Not ideal for: Power users requiring extensive storage or high-performance multitasking, due to its two-bay limit.

    • Storage Bays:2
    • CPU:Intel
    • Transfer Speed:282 MB/s
    • Surveillance Support:Up to 30 IP cameras
    • Warranty:3 years
    Our verdict
    “This NAS suits users prioritizing simple, reliable cloud and media functions over large storage capacity.”
  9. 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 High-Speed Needs

    View on Amazon

    The Asustor Drivestor 4 Gen 2 features a 1.7GHz quad-core processor and 2.5GbE network port, providing solid performance for home and small office environments. Its array of RAID options, including 0, 1, 5, 6, and 10, offers flexible data redundancy tailored to different storage needs. Compared to the UGREEN NAS DXP4800 GT with higher network speeds and expandability, the Drivestor offers a simpler setup but less raw throughput. Its 4K media support ensures smooth streaming, while Btrfs snapshots and remote access add to its versatility. The main limitation is its modest 1GB RAM, which can hamper multitasking if many applications run simultaneously. This NAS is best for users who want a straightforward, reliable device for media and backups without advanced hardware requirements.

    Pros:
    • Supports multiple RAID configurations for data redundancy
    • 2.5GbE port offers faster network speeds than traditional Gigabit Ethernet
    • Supports 4K media streaming and Btrfs snapshots
    • Flexible RAID and remote access features
    Cons:
    • Limited 1GB RAM restricts multitasking performance
    • Diskless, requiring separate drive purchase

    Best for: Home users and small offices seeking a reliable, easy-to-configure NAS with good redundancy options.

    Not ideal for: Power users or creators needing maximum network speed and high RAM capacity for intensive multitasking.

    • Processor:Realtek RTD1619B 1.7GHz Quad-Core
    • RAM:1GB DDR4
    • Network:2.5GbE
    • Drive Bays:4
    • Supported RAID:0/1/5/6/10
    • Media Support:4K streaming
    Our verdict
    “This NAS is ideal for users who prioritize reliable redundancy and media streaming over raw speed or expandability.”
  10. Synology 2-Bay DiskStation DS223j (Diskless)

    Synology 2-Bay DiskStation DS223j (Diskless)

    Best for Entry-Level Private Cloud and Surveillance

    View on Amazon

    The Synology DS223j offers a compact, energy-efficient design perfect for creating a private cloud and basic media sharing. Its two bays limit maximum storage, but make it simple to set up and manage for small households. The Intel CPU ensures reliable performance for streaming and backups, though its limited RAM (2GB) could slow down multitasking with multiple users. The device supports automated backups and surveillance IP camera integration, adding to its versatility. Its energy-efficient operation and quiet design make it suitable for home offices or small businesses. However, users needing large-scale storage or high-performance multitasking should consider larger models. This NAS excels at straightforward cloud and media functions but is less suited for intensive workloads.

    Pros:
    • Creates a private cloud for secure data sharing
    • Supports automated backups and surveillance
    • Energy-efficient and quiet operation
    • Reliable 2-year warranty
    Cons:
    • Limited storage capacity with only two bays
    • Requires purchasing drives separately

    Best for: Small households or remote workers looking for a dependable, easy-to-manage private cloud and security setup.

    Not ideal for: Power users or larger teams requiring extensive storage or advanced multitasking capabilities.

    • Number of Bays:2
    • Warranty:2 years
    • Built-In Media:Yes
    • UPC:846504004768

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

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

    Best for External RAID Expansion for Power Users

    View on Amazon

    The QNAP TR-004 stands out for its robust hardware RAID options and broad compatibility, making it a versatile choice for users who need external storage expansion. Unlike the Synology DS423, which is designed as a full NAS rather than a DAS, the TR-004 offers more flexible RAID configurations like RAID 5 and JBOD, suitable for those who want tailored performance and redundancy. However, its lack of native NAS features means it can’t serve as a standalone server or run applications internally, which could be a limitation compared to a dedicated NAS like the Asustor Drivestor 4 Pro. The device’s lockable drive bays add security, but it won’t recognize data drives migrated from other systems, potentially complicating data management. This pick makes sense for professionals or advanced home users who already own a NAS and want to extend storage capacity securely and efficiently via direct attachment.

    Pros:
    • Supports multiple RAID configurations for flexible data management
    • Compatible with Windows, macOS, and Linux systems
    • Lockable drive bays enhance physical security
    • Expands NAS storage capacity easily
    Cons:
    • Does not support NAS models like the Synology DS423 or DS425+
    • Cannot function as a standalone NAS or run internal applications
    • Data may not be recognized if drives are migrated between different systems

    Best for: Power users and IT professionals needing external RAID storage to expand their existing NAS setup or for backup purposes

    Not ideal for: Beginners or home users looking for an all-in-one NAS solution with integrated apps and media services

    • Number of Bays:4
    • Interface:USB Type-C
    • Supported Systems:Windows, macOS, Linux
    • Drive Compatibility:3.5-inch SATA 3Gb/s
    • RAID Support:RAID 0, 1, 5, JBOD, individual disks
    • Included Cables:USB Type-C to Type-A
    Our verdict
    “This device is ideal for tech-savvy users seeking a reliable external RAID expansion, not for those wanting a standalone NAS or media server.”

Factors to Consider When Choosing Network Attached Storage 4 Bay

Choosing the right 4-bay NAS involves several key considerations that go beyond basic specs. Understanding your primary use—whether for backup, media streaming, or business applications—helps narrow options. Pay attention to CPU power, RAM, and expandability, as these determine future-proofing. Ease of setup and user interface are critical for beginners, while advanced users should prioritize hardware features like RAID support and network speeds. Cost is important, but the most expensive model isn’t always the best fit; balance your needs against your budget to avoid overpaying for features you won’t use. Lastly, consider the software ecosystem and customer support, which can significantly impact your experience over time.

Performance and Hardware Specifications

For a 4-bay NAS, CPU power, RAM, and network throughput directly influence your experience. High-performance CPUs and ample RAM support multiple users, large files, and intensive applications like media editing or virtual machines. If you plan to run surveillance or host complex services, prioritize models with hardware acceleration and fast network interfaces. However, more powerful hardware usually comes at a higher cost, and for casual use, entry-level options may suffice. Balance hardware specs with your actual workload to avoid overspending on unnecessary power.

Ease of Use and Software Ecosystem

A user-friendly interface and reliable software support are vital, especially for beginners. Brands like Synology excel here with intuitive OS and extensive app ecosystems, making setup and management straightforward. For tech-savvy users, advanced features and customization options matter more, but they shouldn’t come at the expense of stability. Compatibility with your existing devices, mobile apps, and cloud integrations are also worth considering. Keep in mind that a complex system can introduce a learning curve that delays getting your NAS operational.

Expandability and Future-Proofing

While 4 bays are fixed, some models offer expandability through additional network ports, SSD caching, or support for external drives. Consider whether the NAS supports upgrades like increased RAM or additional network interfaces, which can extend its lifespan. RAID support is critical for data redundancy, but check how easy it is to configure and manage. A model with better expandability will adapt to your growing data needs or changing workflows, making it a smarter long-term investment.

Price and Value

Pricing varies widely in the 4-bay NAS market, often reflecting hardware capabilities and software features. Be cautious of models that cut corners on critical specs to lower price, as this can impact reliability or speed. Conversely, premium options may offer features you never use, inflating the cost. Focus on models that provide the best balance of features and affordability for your specific needs, rather than simply opting for the most expensive or cheapest choice. Remember, a slightly higher initial investment can pay off through better durability and performance.

Support and Ecosystem Compatibility

Reliable customer support and a strong software ecosystem can make a significant difference in your experience. Brands like Synology and QNAP have established reputations for software updates and community support, which can save time and frustration. Ensure the NAS software supports your preferred backup solutions, media platforms, and remote access. Compatibility with existing devices and cross-platform integration can streamline your workflow and reduce setup headaches. A well-supported device often remains useful and secure over its lifespan, justifying a slightly higher price point.

Frequently Asked Questions

Can I add more storage to a 4-bay NAS later?

Most 4-bay NAS devices support RAID configurations and some allow for external drive connections, but the internal bays are fixed. To expand storage, you can replace existing drives with larger ones or connect external drives via USB or eSATA ports, if available. Some models also support expansion units, although these are less common. Planning your storage needs upfront helps avoid the hassle of replacing drives multiple times. Keep in mind that expanding storage without reconfiguring RAID may risk data integrity, so proceed carefully.

Is a diskless NAS worth it over one with drives pre-installed?

Choosing a diskless NAS offers flexibility to select drives tailored to your performance and capacity needs. It can be more cost-effective and allows you to upgrade drives over time. However, it requires some technical know-how to install and configure drives properly. Pre-installed models are more straightforward, especially for beginners, but they often come at a premium and limit customization. If you’re comfortable with hardware setup, a diskless NAS typically provides better long-term value and adaptability.

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

The CPU’s role is crucial depending on your intended use. For simple file sharing or backups, a basic dual-core CPU will suffice. If you plan to run media servers, surveillance, or virtual machines, a more powerful processor improves responsiveness and multitasking. Higher-end CPUs also support faster encryption and decoding, which benefits media streaming. Assess your workload carefully; investing in a more capable CPU can delay the need for an upgrade later, especially if you want a device that handles multiple demanding tasks.

What’s the advantage of a NAS with multiple network ports?

Having multiple network ports allows for link aggregation, which can increase throughput and provide redundancy. This is especially useful in small business environments or multi-user households where multiple devices access the NAS simultaneously. It also enables network segmentation, improving security and performance. However, to fully utilize multiple ports, your network infrastructure must support link aggregation and be configured correctly. For most home users, a single gigabit port is sufficient, but for higher data demands, multi-port support becomes valuable.

Should I prioritize hardware specs or software features when choosing a NAS?

Both hardware and software are important, but the ideal choice depends on your specific needs. Hardware specs determine how well the NAS will perform under load, especially if you use intensive applications. Software features, including user interface, app ecosystem, and security updates, influence ease of use and long-term reliability. For casual users, an intuitive interface might outweigh raw hardware power. Conversely, power users should prioritize hardware capabilities and expandability. Balancing both aspects ensures your NAS remains functional and manageable as your needs evolve.

Conclusion

For most users, the Synology DS423 offers the best overall experience, combining ease of use, reliable hardware, and a solid software ecosystem. Budget-conscious buyers should consider the UGREEN DXP4800 Plus for its value and user-friendly features. Power users or small businesses will benefit from models like the Asustor Drivestor 4 Pro, which provide hardware flexibility and expandability. Beginners or those new to NAS should focus on simplicity and support, making models like the Synology DS225+ a smart choice. Ultimately, your selection should align with your technical comfort, storage needs, and intended workload.
