More Details on Our Top Picks

  1. 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 High-Performance Multi-User Workflows

    View on Amazon

    This model stands out for its powerful AMD Ryzen Embedded processor, making it ideal for creators and tech-savvy teams who run resource-intensive tasks like virtual machines, media editing, or surveillance. Compared with the UGREEN NAS DXP4800 Pro, it offers less expandability in RAM but excels in raw multitasking ability and network throughput with dual 10GbE ports. The complex setup and lack of included drives mean it’s better suited for users comfortable with advanced configurations and additional purchases. Its high-performance hardware delivers smooth multitasking, but the price and complexity might deter casual users. Drives are not included, so expect extra costs for storage, and the non-ECC RAM limits reliability for critical data.

    Pros:
    • High-performance AMD Ryzen processor supports demanding workflows
    • Expandable storage up to 144TB with multiple SSD options
    • Dual 10GbE ports for fast network speeds
    • Built-in surveillance and virtual machine support
    Cons:
    • Drives not included, additional purchase required
    • Complex setup for advanced features like Docker and VM hosting
    • Pre-installed RAM is non-ECC, limiting data integrity

    Best for: Tech professionals or small business teams needing flexible, high-capacity, multi-user workflows with security features.

    Not ideal for: Casual home users or small offices with simple storage needs who prefer plug-and-play solutions.

    • Processor:AMD Ryzen Embedded R2514, 4 cores, up to 3.70GHz
    • RAM:8GB DDR4, expandable to 64GB
    • Storage Capacity:Up to 144TB (4 bays, 32TB each, with NVMe SSD support)
    • Network:Dual 10GbE ports, support for Link Aggregation
    • Drive Bays:4 SATA, 2 U.2 NVMe SSD, 2 M.2 SSD slots
    • Connectivity:USB 3.0, USB-C, HDMI, SD card slot

    Asustor Drivestor 4 Gen 2 AS1204T 4-Bay NAS, Quad-Core 1.7GHz, 2.5GbE, 1GB DDR4, USB 3.0, Diskless

    Best for Home and Small Office Media Use

    View on Amazon

    This NAS excels as a straightforward, reliable option for home users or small offices, offering a 2.5GbE network for faster data transfers compared to traditional Gigabit models like the TERRAMASTER F4-425. While its quad-core Realtek processor and 1GB RAM support 4K media streaming and basic file sharing, it falls short of the high-end performance seen in the UGREEN NAS DXP4800 GT or UGREEN NAS DXP4800 Pro. Its diskless design is a plus for those wanting to choose their drives, but this also means extra upfront costs. The setup may be straightforward for those familiar with NAS configurations, yet beginners might find it less intuitive. Overall, it balances speed and simplicity for non-intensive workloads.

    Pros:
    • High-speed 2.5GbE network for faster data transfers
    • Supports multiple RAID configurations for data safety
    • Ideal for 4K media streaming and personal cloud access
    • Diskless, allowing custom drive configurations
    Cons:
    • Limited RAM may restrict multitasking
    • No included drives, increasing initial costs
    • Complex setup for beginners

    Best for: Home users or small office teams seeking reliable media streaming and data backup without complex enterprise features.

    Not ideal for: Power users needing virtualization, AI features, or extensive expandability, which this model cannot support.

    • Processor:Realtek RTD1619B 1.7GHz Quad-Core
    • RAM:1GB DDR4
    • Network:2.5GbE port
    • Drive Bays:4
    • Connectivity:3 USB 3.0 ports
    • Storage Type:Diskless
    Our verdict
    “This NAS offers a solid balance of speed and simplicity, perfect for media-focused home or small office users who want flexibility without enterprise complexity.”
  3. 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 clearly targets IT professionals and power users who need serious processing power and expandability. Its Intel Core i3-1315U CPU and support for Docker, VMs, and AI make it stand apart from the less versatile Asustor Drivestor 4. While its extensive RAM capacity and enterprise-grade security are major advantages, the setup process is more involved, and the higher price limits accessibility for casual users. This model is ideal for those who require high reliability, complex workflows, and maximum configurability, yet it may be overkill for simple backups or media streaming.

    Pros:
    • Powerful Intel Core i3 processor supports demanding tasks
    • Supports Docker, VMs, and AI integrations for versatility
    • Massive RAM capacity up to 96GB for multitasking and virtualization
    • Enterprise-grade security features
    Cons:
    • High cost and complex setup require technical expertise
    • Larger physical size and power consumption
    • Potential overkill for simple data backup needs

    Best for: Developers, IT pros, and power users needing virtualization, AI, and large-scale storage management.

    Not ideal for: Home users or small offices with basic backup or media needs, as they will find it too complex and expensive.

    • Processor:Intel Core i3-1315U, 6 cores, up to 4.5GHz
    • RAM:8GB DDR5, expandable to 96GB
    • Storage Capacity:144TB (supports HDDs and M.2 SSDs)
    • Network Ports:10GbE + 2.5GbE
    • Supported RAID:0, 1, 5, 10
    • Operating System:UGOS Pro
    Our verdict
    “This NAS is suited for professionals running intensive virtualized environments and AI tasks, with a tradeoff in complexity and cost.”
  4. 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 for Home Media and Basic Multi-User Sharing

    View on Amazon

    The TERRAMASTER F4-425 offers a practical, budget-friendly choice for home users and small offices, with a solid Intel x86 quad-core processor and 4GB RAM. Its support for 4K transcoding and multiple streaming services like Plex or Jellyfin makes it suitable for media-heavy households. Compared to the UGREEN NAS DXP4800 GT, it lacks high-end networking and enterprise features but excels in quiet operation and straightforward setup. Since it doesn’t include drives, users should be prepared for additional costs. Its maximum storage capacity of 120TB suits most home needs but might fall short for larger small business setups.

    Pros:
    • Powerful quad-core Intel processor supports 4K transcoding
    • Quiet operation at 21dB suitable for home environments
    • Easy, tool-free HDD installation
    • Supports multi-user access and media streaming
    Cons:
    • Maximum storage limited to 120TB
    • No included disks, so storage costs are additional
    • Advanced features may require technical knowledge

    Best for: Home users or small offices needing reliable media streaming and simple file sharing at an affordable price.

    Not ideal for: Power users or businesses requiring virtualization or extensive security features, as this model offers limited expandability and power.

    • Processor:Intel x86 quad-core
    • RAM:4GB
    • Max Storage:120TB
    • Network Ports:2.5GbE
    • Number of Bays:4
    • Compatibility:Plex, Emby, Jellyfin, DLNA
    Our verdict
    “This NAS offers dependable media and file sharing for home or small office use at an accessible price, with some limitations on expandability.”
  5. UGREEN NAS DH4300 Plus 4-Bay Network Attached Storage for Home Use

    UGREEN NAS DH4300 Plus 4-Bay Network Attached Storage for Home Use

    Best for Cost-Effective Home Storage with AI Features

    View on Amazon

    The UGREEN NAS DH4300 Plus provides a compelling option for budget-conscious households seeking secure, reliable storage with AI-powered features like photo organization. Its 2.5GbE network offers faster transfers than standard Gigabit models like the TERRAMASTER F4-425, and its 8GB LPDDR4X RAM enhances performance for everyday tasks. While it lacks Wi-Fi support, its emphasis on security and easy remote access makes it an attractive choice for users who prioritize privacy and automation. However, since drives are sold separately, initial costs can add up, and it doesn’t support virtual machines or complex server functions.

    Pros:
    • Cost-effective solution with high capacity up to 128TB
    • AI-powered photo organization and automatic backups
    • 2.5GbE port for faster data transfer
    • Supports Docker for versatile applications
    Cons:
    • No Wi-Fi support, relying solely on wired Ethernet
    • Storage drives are sold separately, increasing upfront costs
    • Limited virtual machine support

    Best for: Home users wanting automatic backups, AI photo organization, and affordable long-term storage.

    Not ideal for: Small businesses or power users who need virtualization, extensive security, or high network throughput.

    • Number of Bays:4
    • Network:2.5GbE Ethernet
    • RAM:8GB LPDDR4X
    • Max Capacity:128TB
    • Supported Apps:Docker, Plex via Docker
    • Connectivity:Wired Ethernet only
    Our verdict
    “This NAS is well-suited for home users seeking affordable, intelligent storage with remote access and automation features.”
  6. Synology 4-Bay DiskStation DS925+ (Diskless)

    Synology 4-Bay DiskStation DS925+ (Diskless)

    Best Overall for High-Performance NAS

    View on Amazon
    The Synology DS925+ stands out for its exceptional data transfer speeds and robust network redundancy, making it ideal for business environments that require reliable, high-speed access. Compared with the QNAP TS-464-8G-US, it offers slightly faster read/write speeds and supports advanced storage management solutions, but it requires purchasing drives separately, which adds to the initial cost. Its dual 2.5GbE ports provide network resilience, a key advantage over more basic models. This NAS is well-suited for virtualization, data protection, and surveillance, though the diskless setup may deter casual users who want an all-in-one package. Pros:
    • High data transfer speeds (522/565 MB/s)
    • Redundant network ports for increased reliability
    • Supports multiple storage management solutions
    Cons:
    • Diskless setup requires separate drive purchase
    • No included drives, increasing initial expense

    Verdict: A powerful choice for professionals needing speed and reliability, but less suitable for beginners or those seeking an all-in-one package.

    Pros:
    • High data transfer speeds (522/565 MB/s)
    • Redundant network ports for increased reliability
    • Supports multiple storage management solutions
    Cons:
    • Diskless setup requires separate drive purchase
    • No included drives, increasing initial expense

    Best for: Small businesses or IT professionals needing high throughput and network redundancy

    Not ideal for: Home users or casual users seeking an affordable, ready-to-use NAS without additional drive costs

    • Drive Bays:4
    • Network Ports:2 x 2.5GbE
    • Sequential Read/Write:522/565 MB/s
    • Warranty:3 years
    Our verdict
    “This NAS excels in professional settings where speed and reliability are priorities, but less so for plug-and-play home use.”
  7. QNAP TS-433-4G-US 4-Bay NAS

    QNAP TS-433-4G-US 4-Bay NAS

    Best Budget-Friendly Home NAS

    View on Amazon
    The QNAP TS-433-4G-US is tailored for home users seeking reliable media storage and simple backups at an affordable price. Its ARM Cortex-A55 processor and 4GB RAM handle basic tasks well, but fall short for intensive workloads. While it supports fast 2.5GbE connectivity, it lacks additional features like HDMI output or extensive app support found in higher-end models like the TS-464-8G-US. Compared to the Synology DS925+, it offers a more budget-conscious option but with limited performance capacity and upgrade potential. It makes an excellent choice for organizing personal media and simple file sharing but isn’t suited for heavy multitasking or virtualization. Pros:
    • Fast 2.5GbE network port for quick data transfers
    • Good for multimedia streaming and backups
    • Supports Windows and Mac centralized storage
    Cons:
    • Limited to 4GB RAM, restricting multitasking
    • No advanced features like HDMI or app ecosystem

    Verdict: A budget-friendly, straightforward NAS perfect for home media storage and light backup needs.

    Pros:
    • Fast 2.5GbE network port for quick data transfers
    • Good for multimedia streaming and backups
    • Supports Windows and Mac centralized storage
    Cons:
    • Limited to 4GB RAM, restricting multitasking

    • RAM:4 GB DDR4
    • Network Ports:1 x 2.5GbE, 1 x 1GbE
    • Drive Bays:4
    Our verdict
    “This NAS offers straightforward, cost-effective storage for home users focused on media and backup tasks.”
  8. QNAP TS-464-8G-US 4-Bay Desktop NAS

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

    Best for Power Users and Media Enthusiasts

    View on Amazon
    The QNAP TS-464-8G-US offers a robust platform for demanding users, featuring a quad-core Intel N5105/N5095 processor and 8GB DDR4 RAM. Its dual 2.5GbE ports and M.2 NVMe SSD slots allow for fast, cache-accelerated performance. Compared with the Synology DS925+, it provides greater flexibility with SSD caching and a more extensive USB port selection. Its higher performance makes it suitable for multimedia editing, large-scale backups, and running virtual machines, but the setup complexity and lack of included drives might be daunting for less experienced users. For those needing a versatile, performance-driven NAS, it represents a compelling choice. Pros:
    • Fast data transfer with dual 2.5GbE ports
    • Supports SSD cache acceleration for enhanced responsiveness
    • Multiple USB 3.2 ports for external device connectivity
    Cons:

    Pros:
    • Fast data transfer with dual 2.5GbE ports
    • Supports SSD cache acceleration for enhanced responsiveness
    • Multiple USB 3.2 ports for external device connectivity
    Cons:
    • Requires technical setup and configuration
    • Price not specified, potentially costly for some users

    Our verdict
    “This NAS is best suited for power users who prioritize speed, expandability, and performance for demanding tasks.”
  9. 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 Capacity and Advanced Features

Its impressive capacity of up to 144TB paired with 10GbE and high-speed USB ports makes it suitable for small teams or advanced home setups.

Factors to Consider When Choosing 4 Bay Nas

Choosing the right 4 bay NAS depends on understanding several key factors that directly impact your experience and future-proofing. Beyond initial features, it’s vital to consider how a system will fit into your workflow, budget, and growth plans. The following sections cover essential considerations to help you avoid common pitfalls and make an informed decision.

Performance and Hardware Specs

Performance is the backbone of a NAS, especially if you plan to run multiple services or handle large files regularly. Look for a model with a capable processor, at least 2GB of RAM (preferably more for demanding tasks), and network interfaces that match your speed needs, like 2.5GbE or 10GbE. Cheaper options often compromise on CPU power or RAM, which can bottleneck your workflows. For heavy media editing, virtualization, or multi-user environments, investing in higher specs is advisable despite the higher cost.

Ease of Use and Software Ecosystem

An intuitive interface and robust software ecosystem can dramatically reduce setup time and ongoing management. Brands like Synology excel here with user-friendly dashboards and extensive app stores, making complex tasks accessible to less technical users. Conversely, some budget models may lack polish or core features, leading to frustration. Consider how much time you’re willing to spend on configuration and whether the NAS offers features like automatic backups, media streaming, or surveillance integrations that match your needs.

Expandability and Future-Proofing

While 4 bays provide a decent starting point, future growth might require additional storage or upgraded hardware. Check if the NAS supports RAM upgrades, additional network interfaces, or external expansion options. Some models also support SSD caching, boosting performance for certain workloads. Failing to consider expandability can lead to needing a new device sooner than expected, costing more in the long run.

Build Quality and Reliability

Reliability is crucial for data storage — a poorly built NAS can lead to data loss or system failures. Opt for models with solid chassis, good thermal management, and reputable manufacturing. Read reviews to gauge long-term durability and customer support responsiveness. Keep in mind that cheaper devices may save money upfront but could cost more in repairs or replacements if they fail prematurely.

Price and Value

Price often reflects hardware quality and features, but the most expensive isn’t always the best fit. Balance your budget with the features you truly need. For casual backup or media streaming, a less expensive model might suffice. For professional workloads, investing in a higher-end device with faster processors and more RAM delivers better value over time. Watch for models that include essential features bundled in their price to maximize your investment.

Frequently Asked Questions

Can I upgrade the RAM or CPU on a 4 bay NAS?

Upgrading RAM is common on many 4 bay NAS models, especially those aimed at power users, though CPU upgrades are less frequent and depend on the specific hardware design. Before purchasing, verify whether the device supports hardware upgrades; not all do. Upgrading RAM can significantly improve multitasking and performance, particularly if you run multiple services or virtual machines. CPU upgrades are rarer but may be available on higher-end models, providing a substantial performance boost if supported.

Is a 4 bay NAS suitable for media streaming and backups?

Yes, a 4 bay NAS offers a good balance for media streaming, backups, and file sharing, especially if configured with appropriate drives and network settings. Many models support media server apps, enabling streaming to various devices, and can handle regular backups for multiple computers or mobile devices. However, performance depends on hardware specs; models with faster processors and gigabit or multi-gigabit Ethernet are preferable for smooth streaming and quick backups. Always consider your media library size and backup frequency when choosing a model.

Should I choose a diskless NAS or one with drives pre-installed?

Opting for a diskless NAS gives you the flexibility to select drives that match your capacity, performance, and cost preferences. This approach is ideal if you already own drives or want to customize your storage setup. However, pre-installed drives simplify setup and can be more convenient for quick deployment, especially for beginners. Keep in mind that pre-installed options may limit your choice of drives and could be more expensive upfront. Evaluate your comfort with installing drives and your specific storage needs before deciding.

How important is network speed in a 4 bay NAS?

Network speed directly impacts data transfer rates, especially when multiple users access the NAS simultaneously or when transferring large files. Basic gigabit Ethernet is standard but can become a bottleneck under heavy loads. Many high-end models support 2.5GbE, 5GbE, or even 10GbE interfaces, which significantly reduce transfer times and improve overall responsiveness. Consider your current network infrastructure and future needs; investing in higher network speeds can be worthwhile if you work with large media files or have multiple users accessing the NAS regularly.

What is the typical lifespan of a NAS, and how do I maintain it?

The lifespan of a NAS depends on build quality, usage patterns, and environmental factors but generally ranges from 3 to 5 years or more with proper maintenance. Regular firmware updates, monitoring system health, and replacing failing drives promptly extend its life. Proper cooling and avoiding power surges also contribute to longevity. Choosing a reputable brand with good customer support can make maintenance easier and help resolve issues quickly, ultimately prolonging the device’s usefulness and protecting your data.

Conclusion

For casual home users or those new to NAS, the UGREEN NAS DXP4800 Plus offers simplicity and good value. Power users or small teams needing robust performance will find the Synology DS925+ to be an excellent overall choice. Budget-conscious buyers should consider the TERRAMASTER F4-425 for its balance of features and affordability. Those with more demanding workloads or future expansion plans will benefit from investing in higher-end models like the QNAP TS-464-8G-US. Ultimately, your decision should align with your current needs and growth expectations, ensuring your NAS remains a reliable storage partner for years to come.
