More Details on Our Top Picks

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

    Synology 4-Bay DiskStation DS925+ (Diskless)

    Best Overall for Performance and Versatility

    View on Amazon

    The Synology DS925+ stands out for its impressive transfer speeds of up to 565 MB/s, making it a strong choice for users who prioritize fast data access, especially compared to the more modest performance of the UGREEN NAS DH4300 Plus. Its dual 2.5GbE ports provide redundancy and enhanced network bandwidth, suitable for demanding workflows. The device also offers robust software features for file management, data protection, virtualization, and surveillance, making it a versatile solution for prosumers and small businesses. However, it requires users to purchase drives separately, and its complex interface might overwhelm beginners. Compared with the QNAP TR-004, it offers integrated NAS features rather than direct-attached storage, which may matter depending on your setup. Overall, this pick makes the most sense for those who need high speed and comprehensive management tools, accepting the higher initial investment and complexity.

    Pros:
    • High data transfer speeds up to 565 MB/s
    • Dual 2.5GbE ports for network redundancy
    • Versatile management including virtualization and surveillance
    • 3-year hardware warranty
    Cons:
    • Requires separate purchase of drives
    • Interface complexity may be challenging for beginners

    Best for: Small to medium-sized businesses or power users needing high transfer speeds and advanced features.

    Not ideal for: Home users seeking an easy, plug-and-play setup without the need for extensive configuration.

    • 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
    “This NAS is ideal for technically savvy users who demand speed and feature-rich management tools.”
  2. Asustor Drivestor 4 Pro Gen2 AS3304T v2, 4-Bay NAS, Quad-Core, 2GB DDR4, 2.5GbE, Personal Cloud, Diskless

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

    Best for Small Office and Home Use on a Budget

    View on Amazon

    The Asustor Drivestor 4 Pro Gen2 offers a balanced mix of performance and affordability, with a quad-core processor and 2GB RAM that serve well for basic multitasking, especially when compared to the more powerful UGREEN DXP4800 GT. Its 2.5GbE network port ensures faster local transfers, making it suitable for backup and media streaming in small environments. The easy tool-free drive installation simplifies initial setup, ideal for users new to NAS devices. However, its limited RAM may hinder performance during intensive multitasking or multiple simultaneous users, and it doesn’t include drives, adding to the initial cost. It lacks the advanced hardware options of the UGREEN DXP4800 GT, which might be a consideration for more demanding workloads. This model appeals to home users and small offices needing a reliable, straightforward storage solution without overcomplicating setup or breaking the bank.

    Pros:
    • Easy tool-free drive installation
    • Fast 2.5GbE network connectivity
    • Affordable price point
    • Supports flexible RAID configurations
    Cons:
    • Limited 2GB RAM may impact performance
    • Drives not included, additional purchase needed
    • Basic specs may not handle large enterprise workloads

    Best for: Home users or small offices needing a straightforward, budget-friendly NAS for backup and streaming.

    Not ideal for: Power users or businesses with high multitasking demands or large data needs.

    • Processor:Realtek quad-core
    • RAM:2GB DDR4
    • Network:2.5GbE
    • Number of Bays:4
    • Drive Type:Diskless
    Our verdict
    “This NAS suits users who need simple, affordable storage for home or small office use without heavy multitasking.”
  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 External Storage for Flexible RAID Management

    View on Amazon

    The QNAP TR-004 excels as a flexible external storage solution, supporting multiple RAID levels, including RAID 0, 1, 5, and JBOD, giving users control over data redundancy and performance. Its USB Type-C interface offers fast data transfer, especially compared to the typical Ethernet-based NAS options like the Synology DS925+. While it’s not a traditional NAS and doesn’t support network features or drive pooling, it’s ideal for expanding storage for backups and media libraries. The lockable drive bays add security, but its incompatibility with NAS-specific features limits its use cases to direct-attached storage. Compared with the UGREEN NAS DXP4800 GT, it offers greater RAID flexibility but lacks network connectivity and advanced management features. This model works best for users who need a portable, high-speed external drive with robust RAID options, rather than a full-featured network solution.

    Pros:
    • Supports multiple hardware RAID levels
    • Lockable drive bays enhance security
    • Fast USB Type-C data transfer
    • Compatible with Windows, macOS, and Linux
    Cons:
    • No network support or NAS features
    • Limited to 3.5-inch SATA drives only
    • Cannot replace a full NAS for multi-user or remote access needs

    Best for: Power users requiring portable, flexible RAID storage for backups or media libraries.

    Not ideal for: Users wanting an all-in-one network storage or surveillance support.

    • Number of Bays:4
    • Interface:USB Type-C
    • Supported OS:Windows, macOS, Linux
    • RAID Support:RAID 0, 1, 5, JBOD
    • Drive Size:3.5-inch SATA
    • Includes:USB Type-C to Type-A cable
    Our verdict
    “This external enclosure is perfect for those who need portable, fast RAID storage without network features.”
  4. 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 Environments

    View on Amazon

    The UGREEN DXP4800 GT stands out for its powerful AMD Ryzen Embedded R2514 processor, making it well-suited for multitasking and media processing, especially compared to the more basic Asustor Drivestor 4 Pro Gen2. Its expandable storage capacity up to 144TB and dual 10GbE ports support demanding data throughput, ideal for creative teams or small businesses with heavy media workflows. The inclusion of multiple drive types—SATA, NVMe U.2, and M.2 SSDs—adds flexibility for different performance needs. Its built-in surveillance functionality and extensive security features target professional environments. However, drives are sold separately, and its complex setup might be overwhelming for typical home users. The non-ECC RAM limits its use for critical data environments, and the high performance comes at a cost. This NAS makes sense for tech-savvy creators and small teams seeking a robust, expandable storage hub with media and surveillance capabilities.

    Pros:
    • Powerful AMD Ryzen Embedded R2514 processor
    • Expandable storage up to 144TB
    • Dual 10GbE ports for fast networking
    • Supports multiple drive types including NVMe and SATA
    Cons:
    • Drives not included, additional cost
    • Setup complexity may challenge beginners
    • Non-ECC RAM limits critical data reliability

    Best for: Creative professionals or small businesses needing high-speed, expandable, multi-user storage.

    Not ideal for: Home users seeking simple, plug-and-play solutions without complex setup or advanced hardware.

    • Processor:AMD Ryzen Embedded R2514
    • RAM:8GB DDR4, expandable to 64GB
    • Storage Capacity:Up to 144TB
    • Network:Dual 10GbE
    • Drive Bays:4 SATA + 2 NVMe U.2 + 2 M.2 SSD
    • Included Accessories:Power, HDMI, Ethernet cables
    Our verdict
    “This NAS is perfect for tech-savvy users needing high performance, extensive expandability, and advanced media capabilities.”
  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 Entry-Level Home and Remote Storage

    View on Amazon

    The UGREEN NAS DH4300 Plus offers a straightforward, cost-effective solution for home media and remote access needs, making it a good alternative to cloud storage for casual users. Its 8GB RAM and 2.5GbE port deliver decent performance for everyday tasks, outperforming basic single-drive options like some entry-level NAS models. Its simple setup, along with features like automatic photo backup and AI album organization, makes it accessible for less tech-savvy users. While it does not support Wi-Fi or virtual machines, its encryption and remote access capabilities provide a secure private storage environment. Compared with the Synology DS225+, it offers higher capacity and better performance for the same price point, but lacks some enterprise features. This device is ideal for remote workers and families seeking reliable, private storage without complexity.

    Pros:
    • Cost-effective long-term storage
    • Easy setup and remote access
    • Supports Docker for advanced users
    • High transfer speeds for home use
    Cons:
    • No Wi-Fi support
    • Virtual machines not supported
    • Disks sold separately

    Best for: Remote workers and families needing secure, easy-to-use storage with backup and media features.

    Not ideal for: Power users or those requiring virtualization or Wi-Fi connectivity.

    • Capacity:128TB
    • Number of Bays:4
    • Processor:High-performance
    • Network Port:2.5GbE
    • RAM:8GB LPDDR4X
    • Supports Virtual Machines:No
    Our verdict
    “This NAS is suitable for families and remote workers seeking simple, reliable, and private storage with media features.”
  6. Asustor Drivestor 4 Gen 2 AS1204T 4-Bay NAS

    Asustor Drivestor 4 Gen 2 AS1204T 4-Bay NAS

    Best Overall for Home and Small Office Media & Backup

    View on Amazon

    The Asustor Drivestor 4 Gen 2 AS1204T stands out for offering a balanced combination of speed, ease of use, and versatility, especially with its 2.5GbE port supporting fast file transfers. Compared with the Synology DS423, it provides better network performance on a budget but falls short in advanced security features. Its 1GB RAM may be limiting for heavy multitasking, and it lacks included drives, meaning additional purchase is necessary. This device is ideal for users seeking straightforward media streaming and backups without complex setup, but it’s less suited for demanding enterprise workflows that require extensive RAM and security options.

    Pros:
    • Fast 2.5GbE network for quick file transfers
    • Supports multiple RAID levels for data redundancy
    • Easy to set up and operate for non-technical users
    • Supports 4K media streaming
    Cons:
    • Limited 1GB RAM may hinder multitasking
    • No included drives, adding to initial cost
    • Basic hardware might struggle with intensive tasks

    Best for: Home users and small office owners who want reliable media streaming and simple backup solutions

    Not ideal for: Power users or enterprises needing extensive RAM or advanced security features

    • Processor:Realtek RTD1619B 1.7GHz Quad-Core
    • Memory:1GB DDR4
    • Network:2.5GbE Port
    • Drive Bays:4
    • USB Ports:3 USB 3.0
    • Supported RAID:0/1/5/6/10
    • Supported Media:4K streaming
    • Form Factor:Desktop
    Our verdict
    “This NAS offers excellent value for small-scale media and backup needs with straightforward operation.”
  7. 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 Advanced Features

    View on Amazon

    The UGREEN DXP4800 Plus makes a compelling case for users needing vast storage capacity and high-speed data transfer, supporting up to 144TB and featuring 10GbE connectivity. Unlike the Synology DS423, it offers significantly more raw storage and supports advanced features like Docker, virtual machines, and AI photo organization, making it suitable for creative teams and small businesses. However, it requires users to purchase drives separately, and its wired-only Ethernet limits flexibility in some setups. This NAS excels for those who need to manage large multimedia libraries or extensive business data, but it may be overkill and less accessible for casual or home use.

    Pros:
    • Massive storage capacity up to 144TB
    • High-speed data transfer with 10GbE
    • Supports Docker, virtual machines, and AI features
    • Robust security and private cloud options
    Cons:
    • Drives not included, adding to total cost
    • Wired Ethernet only, no Wi-Fi support
    • Setup and maintenance may be complex for average users

    Best for: Professionals, creators, and teams handling large data volumes requiring high transfer speeds and advanced features

    Not ideal for: Users seeking a plug-and-play solution or with limited technical experience due to setup complexity

    • Digital Storage Capacity:144 TB
    • Network Ports:1x 10GbE, 1x 2.5GbE
    • RAM:8GB DDR5
    • SSD:128GB
    • Supported Media Speed:1250 MB/s
    • Form Factor:Desktop
    Our verdict
    “Best suited for creative professionals and teams needing high capacity and advanced virtualization features.”
  8. 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 Enterprise-Grade Security

    View on Amazon

    The UGREEN NAS DXP4800 Pro is engineered for demanding professional environments, with an Intel Core i3 processor and expandable RAM up to 96GB, supporting intensive workflows such as virtualization, large-scale data management, and security. Unlike the UGREEN DXP4800 Plus, it offers enterprise features like data vault encryption and a more powerful CPU, making it ideal for IT professionals and developers. The setup can be complex, and its higher price reflects its advanced capabilities. This NAS is perfect for tech-savvy users needing heavy-duty performance and robust security, but it’s less suitable for casual users or small offices with basic needs.

    Pros:
    • Powerful Intel Core i3 processor with 6 cores
    • Expandable RAM up to 96GB
    • Supports Docker, virtual machines, and enterprise features
    • Security with Data Vault encryption
    Cons:
    • Likely expensive for small-scale use
    • Setup complexity requiring technical knowledge
    • Overkill for casual or light users

    Best for: IT professionals, developers, and power users with demanding workloads and security requirements

    Not ideal for: Small businesses or home users without technical expertise or requiring simpler solutions

    • Processor:Intel Core i3-1315U 6 Cores
    • RAM:8GB DDR5 (expandable to 96GB)
    • Storage Capacity:144TB (4x HDD + 2x M.2 SSD)
    • Network Ports:10GbE + 2.5GbE
    • RAID Support:0, 1, 5, 10
    • Maximum Users:2048
    Our verdict
    “Designed for demanding workflows, this NAS offers enterprise-grade performance and security for experienced users.”
  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 Surveillance Integration

    View on Amazon

    The Synology DS423 excels in providing a secure and reliable platform for data backup, file sharing, and surveillance. Its diskless configuration allows users to customize storage, but it requires purchasing drives separately. Compared with the UGREEN DXP4800 Plus, it offers stronger security features and a focus on data protection with snapshot support. While it supports up to 30 IP cameras, licensing costs apply, and initial setup can be technical. This NAS is ideal for users prioritizing security, data integrity, and surveillance, but less suited for those needing pre-configured storage solutions or higher performance.

    Pros:
    • Secure private cloud access from anywhere
    • Supports snapshots and data protection
    • Compatible with up to 30 IP cameras
    • Reliable hardware with 2-year warranty
    Cons:
    • Camera licenses sold separately
    • Requires technical setup for surveillance
    • No drives included, additional purchase needed

    Best for: Small businesses or home security setups prioritizing data security and surveillance capabilities

    Not ideal for: Users needing large, pre-installed storage or high-speed data transfer for multimedia projects

    • Number of Bays:4
    • Type:Diskless NAS
    • Features:Private cloud, data backup, surveillance
    • Warranty:2 years
    • Supported Cameras:Up to 30
    Our verdict
    “Ideal for security-conscious users seeking flexible data protection and surveillance capabilities.”
  10. Synology DS225+ Private Cloud Media Server – 2-Bay Diskless NAS with Intel CPU for Hardware Transcoding

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

    Best for Home and Small Business Media & Surveillance

    View on Amazon

    The Synology DS225+ offers a compact, efficient solution for media streaming, backups, and smart surveillance, with hardware transcoding supporting 4K media. While its 2-bay design limits storage expansion compared to 4-bay models like the DS423 or UGREEN DXP4800 Plus, it compensates with faster transfer speeds up to 282 MB/s. Its multi-layered data protection, including RAID and snapshots, makes it suitable for small businesses or home users wanting reliable media and surveillance management. However, the diskless setup means additional drive cost and some setup complexity, especially for users unfamiliar with Synology’s ecosystem.

    Pros:
    • Supports 4K media streaming and hardware transcoding
    • Fast transfer speeds up to 282 MB/s
    • Multi-layered data protection including RAID
    • Supports up to 30 IP cameras with AI detection
    Cons:
    • Requires purchasing drives separately
    • Limited to 2 drive bays
    • Setup may be complex for beginners

    Best for: Home users and small businesses needing media streaming and surveillance with fast performance

    Not ideal for: Large-scale data storage or users seeking extensive expansion options

    • Bays:2
    • Processor:Intel CPU
    • Warranty:3 years
    • Max Transfer Speed:282 MB/s
    • Supported Cameras:Up to 30

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

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

    Best for Data Sharing and Business Use

    View on Amazon

    The Synology DS425+ is tailored for businesses and advanced users, offering a high-speed data transfer rate of 278 MB/s that outperforms many competitors like the TERRAMASTER F4-425. Its support for multiple users simultaneously and robust data protection features, including RAID, snapshots, and backups, make it ideal for environments where data security and quick access are priorities. Additionally, its built-in surveillance support for up to 30 IP cameras adds value for security-focused setups. However, it is a diskless model requiring separate drive purchase, and its setup may be complex for less experienced users. While it excels in network speed and data protection, its primary focus on network-based storage means it isn’t portable or suitable for direct-attached scenarios. This pick is perfect for small businesses or remote teams needing reliable, high-speed NAS with advanced data management tools.

    Pros:
    • High-speed 278 MB/s data transfer for efficient file access
    • Supports multiple users with smooth performance
    • Multi-layered data protection including RAID and snapshots
    Cons:
    • Requires purchasing drives separately, adding initial cost
    • Complex setup may challenge beginners

    Best for: Small business owners or IT professionals needing high-speed data sharing and comprehensive protection

    Not ideal for: Home users seeking simple setup or portable storage solutions

    • Brand:Synology

    • Number of Bays:4
    • Network Speed:2.5GbE
    • Warranty:3 years
    • UPC:846504005994
    Our verdict

Factors to Consider When Choosing Network Attached Storage 4 Bay

Choosing the right 4-bay NAS involves considering several key factors beyond just specifications. Understanding your primary use case will help determine which features matter most, such as performance, expandability, or ease of management. Budget constraints also influence whether you should prioritize high-end models or more affordable options. Paying attention to software support and community resources can dramatically affect your experience over time. This guide highlights critical considerations to help you make an informed decision that aligns with your needs and future growth plans.

Performance and Hardware

The processing power, RAM, and network interfaces directly impact how smoothly your NAS handles multiple users, large files, or media streaming. For demanding tasks like 4K video editing or virtualization, a model with a quad-core processor and at least 4GB of RAM is preferable. Cheaper options may suffice for backups or media serving but can struggle under load. Remember, higher performance often comes with increased cost, so match the hardware to your anticipated workload.

Software Ecosystem and Usability

The software platform determines how easy it is to set up, manage, and expand your NAS. Devices from Synology and QNAP are renowned for their intuitive interfaces and extensive app ecosystems, which simplify tasks like backups, media streaming, and remote access. Less established brands might lack robust support, leading to a steeper learning curve. For beginners, a user-friendly interface can save time and frustration, while experienced users may prioritize advanced features and customization options.

Expandability and Connectivity

While 4 bays are fixed, consider how future storage needs might evolve. Some models support additional expansion units or offer faster network ports like 2.5GbE or 10GbE, which can significantly improve transfer speeds. USB ports, HDMI outputs, and compatibility with other devices also add versatility. If you plan to scale your storage or integrate with other hardware, these features can influence your choice.

Price and Total Cost of Ownership

Initial price is just one part of the equation. Diskless models are cheaper upfront but require purchasing drives separately, which can add up. Conversely, pre-populated units cost more initially but save setup time. Consider ongoing expenses like drive replacements, software licenses, or extended warranty plans. Sometimes, investing in a higher-end model reduces long-term hassle and service costs, especially for professional environments.

Security and Data Protection

Data security features like encryption, snapshot support, and remote wipe are vital for protecting sensitive information. Look for models that support regular firmware updates and have robust user management controls. For business or critical data, these features can prevent costly data breaches or loss. Additionally, consider backup options and compatibility with cloud services for added redundancy.

Frequently Asked Questions

Is a 4-bay NAS suitable for a small home office?

Yes, a 4-bay NAS provides ample storage capacity for a small home office, allowing for centralized data management, backups, and media streaming. It offers enough room for multiple users and can be expanded with additional drives or features, depending on the model. For most home offices, an easy-to-use interface and reliable performance are more important than high-end enterprise features, making models from Synology or UGREEN good options.

Should I buy a diskless 4-bay NAS or one with drives pre-installed?

Choosing between a diskless model and one with drives pre-installed depends on your budget and technical comfort. Diskless units are typically less expensive initially and give you the flexibility to choose drives that suit your needs. However, this requires additional setup time and effort. Pre-installed models save time and ensure compatibility but often come at a higher upfront cost. Consider your familiarity with hardware installation and whether you want to customize your storage configuration.

How important is network speed in choosing a 4-bay NAS?

Network speed is critical if you plan to access large files frequently or stream high-resolution media. Models with 2.5GbE or 10GbE ports can dramatically reduce file transfer times compared to standard Gigabit Ethernet, especially with multiple users. If your network infrastructure doesn’t support these speeds, investing in higher port options may not provide immediate benefits, but future-proofing your setup is a smart move for growth.

Can a 4-bay NAS handle multiple users simultaneously?

Yes, most 4-bay NAS devices are designed to support multiple users at once, but actual performance depends on hardware specifications like CPU and RAM. For environments with many concurrent users or heavy data transfer needs, models with higher-end processors and more memory perform better. Additionally, network interface speed and software optimization influence the user experience, so choose a device that matches your expected workload.

What should I consider for data security on my NAS?

Data security features such as encryption, user access controls, and automatic backups are essential for protecting sensitive data. Look for models that support regular firmware updates and have robust security protocols. Features like snapshot backups and remote wipe capabilities provide additional layers of protection. For business use, compliance with data protection standards and integration with external security tools can be equally important.

Conclusion

If you’re a home user or small team prioritizing ease of use and reliable software, the Synology DS925+ stands out as the best overall choice. For those on a budget who want decent performance with straightforward setup, the UGREEN NAS DXP4800 GT is a compelling option. Professionals or power users needing maximum flexibility should consider the QNAP TR-004 for its hardware RAID options. Beginners or casual users will benefit from models that combine simplicity with essential features, while enterprise users might lean toward higher-end, expandable solutions. Matching your specific needs to these profiles will ensure a satisfying purchase.
