More Details on Our Top Picks

  1. 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 Overall for High Performance and Versatility

    View on Amazon

    The TERRAMASTER F4-425 stands out for its robust hardware, featuring an Intel x86 quad-core processor and 4GB of RAM, making it suitable for demanding tasks like 4K transcoding and multi-user access. Compared with the Synology DS225+, it offers higher performance potential for media streaming and data handling, though it requires users to purchase disks separately, unlike the Synology which includes a user-friendly interface out of the box.

    Asustor Drivestor 4 Pro Gen2 AS3304T v2, 4-Bay NAS, Quad-Core, 2GB DDR4, 2.5GbE, Personal Cloud, Diskless

    Best for Fast Networking and Basic Data Protection

    View on Amazon

    The Asustor Drivestor 4 Pro Gen2 offers a solid balance of speed and simplicity, powered by a quad-core Realtek processor and equipped with 2GB DDR4 RAM. Its 2.5GbE connectivity distinguishes it from many competitors like the Ugreen NAS DH4300 Plus, providing significantly faster data transfer for home backups and small office workflows. Its easy, tool-free drive installation makes setup straightforward, yet its modest 2GB RAM can limit multitasking performance under heavy loads.

    • Drive Bays:4
    Our verdict
    “Ideal for users seeking a fast, straightforward NAS for backup and personal cloud storage without complex features.”
  3. 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 Expanding Storage and Drive Security

    View on Amazon

    The QNAP TR-004 provides an external, versatile storage solution that complements NAS setups like the Synology DS425+ by expanding capacity through hardware RAID support. Its USB Type-C interface ensures quick data transfer, and the lockable drive bays add a layer of physical security. While it offers multiple RAID configurations, it does not support NAS-specific features like file sharing or cloud sync, making it more suitable for backups and direct storage expansion. The limitation is its confinement to 3.5-inch SATA drives, which might restrict compatibility for some users. Compared to NAS devices, it lacks network connectivity, but it excels in straightforward, secure external storage.
    This pick is best for users needing reliable, flexible external storage that can easily connect to various systems.

    Pros:
    • Supports multiple RAID levels for flexible data management
    • Compatible with Windows, macOS, and Linux systems
    • Lockable bays enhance physical security
    • Fast data transfer via USB Type-C

    • Drive Size:3.5-inch SATA
    • Includes:USB Type-C to Type-A cable
    Our verdict
    “Best for expanding storage and securing data externally, especially when flexibility and security matter.”

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

    Best for Media Enthusiasts and Small-Scale Streaming

    View on Amazon

    The Synology DS225+ offers a compact, energy-efficient solution for media streaming, backup, and surveillance, with an Intel CPU supporting hardware transcoding for 4K media. Compared to the Ugreen NAS DH4300 Plus, its dual bays restrict storage expansion but provide a more user-friendly interface and robust media features. Its transfer speeds reach up to 282 MB/s, ideal for streaming multiple 4K videos and managing a small surveillance system with support for 30 IP cameras. The main downside is its diskless design, requiring users to purchase drives separately, and its limited bay count might restrict larger storage needs. It’s best suited for users who prioritize media performance and data security over maximum capacity.
    This NAS is perfect for media collectors and small households focused on multimedia and smart surveillance integration.

    Pros:

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

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

    Best for Cost-Effective Home Storage and Remote Access

    View on Amazon

    The UGREEN NAS DH4300 Plus emphasizes affordability and ease of use, making it a strong choice for beginners or remote workers requiring private storage. Its 8GB LPDDR4X RAM and high-performance processor support smooth operation for daily backups, media, and remote access. Unlike some enterprise models, it doesn’t support Wi-Fi, focusing solely on wired Ethernet, which may limit flexibility for some users. The device’s support for Docker enables some advanced users to run virtualized apps, but it does not support virtual machines directly. The main tradeoff is its lack of included disks and limited scalability beyond 128TB, but its user-friendly setup and encryption features suit home and small team environments well.
    This pick makes the most sense for users seeking reliable, secure storage with simple remote access and moderate performance needs.

    Pros:
    • Cost-effective solution compared to cloud subscriptions

    View on Amazon

    The Synology DS425+ stands out for its high-speed data transfer capabilities, reaching 278 MB/s, which makes it ideal for multi-user environments that demand quick, reliable file sharing. Compared to the Synology DS925+, it offers similar network speeds but with a simpler setup, making it a strong choice for small to medium businesses. Its multi-layered data protection, including RAID, snapshots, and backups, adds peace of mind for critical data.

  8. Synology 4-Bay DiskStation DS925+ (Diskless)

    Synology 4-Bay DiskStation DS925+ (Diskless)

    Best for Versatile Business and IT Applications

    View on Amazon

    The Synology DS925+ combines excellent data transfer speeds, reaching up to 565 MB/s for writing, with dual 2.5GbE ports, making it well-suited for demanding business environments. Compared to the QNAP TR-004, it offers more comprehensive management, data protection, and virtualization features, though at a higher price point. Its support for drives from a certified list ensures reliability but requires users to purchase drives separately.

    View on Amazon

    The UGREEN DXP4800 Pro is engineered for enterprise-grade performance, featuring an Intel Core i3-1315U processor capable of heavy multitasking, virtual machines, and Docker containers. Compared to the Asustor Drivestor 4 Pro, it offers vastly more expansion options, including support for 96GB RAM and multiple RAID configurations. Its support for advanced security features like Data Vault encryption makes it suitable for sensitive data workflows.

    View on Amazon

    The Asustor Drivestor 4 Gen 2 offers a straightforward, reliable solution for home and small office users. With its quad-core 1.7GHz processor and 2.5GbE port, it supports fast network transfers and 4K media streaming, making it a solid choice for personal cloud storage and media libraries. Its simple setup process makes it accessible for users unfamiliar with network storage, unlike more complex options like the UGREEN DXP4800 Pro.

Factors to Consider When Choosing Network Attached Storage 4 Bay

Choosing the right 4-bay NAS involves weighing several key factors to match your specific needs. Beyond basic storage capacity, consider performance, ease of use, expandability, and future-proofing. Making the wrong choice can lead to frustration or the need for costly upgrades later. Here are some important considerations to help refine your decision and avoid common pitfalls.

Performance and Hardware Power

Performance is crucial if you plan to run intensive applications like media transcoding or large-scale backups. Look for CPUs with higher core counts and sufficient RAM—especially if your workload involves multiple users or demanding tasks. Keep in mind that some models, like Synology DS925+, are better suited for professional environments, while others prioritize simplicity over raw power.

Ease of Use and Software Ecosystem

The user interface and software features significantly impact your experience, especially if you’re new to NAS. Synology’s DiskStation Manager is widely praised for its intuitive design, whereas other brands may have steeper learning curves. Consider whether the software supports your favorite apps, streaming, or remote access, which can influence daily usability.

Expandability and Future-Proofing

Some NAS units support additional RAM or hardware upgrades, which can extend their lifespan and performance. Check if the device offers hardware RAID options, multiple Ethernet ports, or expansion slots. These features are important if your data storage needs are expected to grow or if you want to integrate the NAS into a larger network.

Connectivity and Network Speed

Faster network interfaces like 2.5GbE or 10GbE are increasingly common, reducing bottlenecks for data transfer. Consider your current network infrastructure and whether the NAS can leverage these speeds. A device with a single Gigabit port may suffice for light use but could limit performance in more demanding environments.

Price and Total Cost of Ownership

Budgeting for a NAS involves not just the device cost but also potential expenses for drives, upgrades, and maintenance. Entry-level models tend to be more affordable but might lack advanced features, while premium options offer more power and flexibility at a higher price. Balance your immediate needs with future requirements to avoid overspending or underbuying.

Frequently Asked Questions

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

Choosing between diskless and pre-installed drives depends on your comfort with hardware setup and your specific needs. Diskless NAS units are generally more flexible and allow you to select drives that match your performance and capacity preferences. However, pre-installed drives can save time and reduce compatibility concerns, especially for users unfamiliar with hardware installation. Consider whether you prefer a DIY approach or a ready-to-use solution.

Is a 2.5GbE port worth the extra cost over Gigabit Ethernet?

Upgrading to a 2.5GbE port can significantly improve data transfer speeds if your network infrastructure supports it. For users transferring large files regularly or streaming high-definition media, this can reduce bottlenecks. However, if your current network is limited to Gigabit Ethernet, the benefits may be minimal unless you plan to upgrade your entire network later.

How much RAM do I need in my NAS for smooth operation?

The amount of RAM affects multitasking and media transcoding capabilities. Basic tasks might be fine with 2GB, but for running multiple apps or handling media streams, 4GB or more is recommended. Power users or those running virtual machines or containerized applications should consider models with even higher RAM capacity to maintain smooth operation.

Are hardware RAID configurations necessary for home use?

Hardware RAID can improve data redundancy and performance, especially if you store critical data. For home users with less demanding needs, software RAID or regular backups might suffice. Hardware RAID offers more seamless management and faster recovery, but it also adds complexity and cost. Your choice should reflect the importance of data safety versus simplicity.

Can I upgrade or expand the storage later?

Many 4-bay NAS units support adding drives or upgrading existing ones, but the extent varies. Some models allow RAM upgrades or hardware expansions, extending their lifespan as your needs grow. Always check the manufacturer’s specifications for support of additional drives, compatible drives, and upgrade options before making a purchase. Planning for future expansion can save money and hassle later.

Conclusion

For most users, the Synology DS925+ offers the best overall experience with its combination of power, ease of use, and reliable software. Those on a tighter budget or seeking straightforward setup might prefer the UGREEN NAS DH4300 Plus for its simplicity. Power users and professionals should consider models like the TERRAMASTER F4-425 for maximum hardware flexibility, while beginners or remote workers benefit from models designed for effortless operation. Ultimately, your choice should align with your technical comfort, storage needs, and future plans.
