Acquiring a NAS (Network Attached Storage) often serves as the cornerstone of a modern homelab, acting as the backbone for data centralization, lightweight virtualization, and multimedia streaming. For a beginner looking to balance ease of use with sufficient performance for Docker or Plex, the 2-bay form factor remains the ideal compromise between cost, footprint, and expansion capacity. By 2026, the market has evolved significantly with the arrival of more powerful ARM processors and more open operating systems, making the choice less straightforward than it was a few years ago. This guide analyzes three flagship models: the Synology DS224+, the QNAP TS-264 (often preferred over the TS-233 for its virtualization performance), and the new UGREEN NASync DXP2800. The goal is to demystify the technical specifications to help you choose the platform that will serve as the foundation for your Docker containers, incremental backups, and media library, without getting lost in unnecessary features or marketing traps.

Why this choice matters

Choosing a 2-bay NAS is not just about raw storage space. It is an architectural decision that will impact the fluidity of your homelab in the long term. Three technical criteria are decisive. First, CPU power and the presence of hardware transcoding engines are crucial if you plan to use Plex or Jellyfin. A processor incapable of transcoding video in real time will force the client device to do it, increasing CPU load and degrading the user experience. Second, expandable RAM is the number one limiting factor for running Docker services. A NAS with 1 GB of soldered RAM will not be able to run Home Assistant, a file server, and a database simultaneously without swapping, which drastically reduces the lifespan of the internal SSD and the system's responsiveness. Third, the philosophy of the operating system (OS) dictates your learning curve. A closed and locked-down OS guarantees stability but limits automation, while a more open OS offers total flexibility at the cost of more demanding maintenance. Finally, idle power consumption must be taken into account for a device running 24/7, as it represents a significant hidden cost over several years.

Buying criteria

To filter offers, you need to focus on tangible metrics. The bay format must accept 3.5-inch drives to maximize capacity per unit cost, while also allowing the use of NVMe SSDs for cache or primary storage if the model supports it. Network connectivity is paramount: Gigabit Ethernet is the absolute minimum, but the presence of a 2.5GbE port quickly becomes essential to avoid bottlenecks during local transfers or large file backups. RAID 1 (mirroring) compatibility is mandatory for data redundancy; ensure the NAS offers automatic and reliable RAID reconstruction. The OS should offer intuitive user and permission management, as well as a rich application catalog. For the homelab, the ability to install native Docker packages or via third-party methods (such as Docker-Compose) is a major advantage. Energy consumption, measured in Watts at idle, should be under 15W for responsible home use.

Synology DS224+

The Synology DS224+ remains the market reference for those who prioritize stability and the software ecosystem. It is equipped with a Realtek RTD1619B quad-core 1.7 GHz processor, accompanied by 2 GB of soldered DDR4 RAM, expandable up to 6 GB via a SO-DIMM slot. This expandability is a critical strength, as 2 GB are insufficient for a modern homelab. Synology's major advantage lies in its operating system, DSM (DiskStation Manager), renowned for its stability, security, and the quality of its proprietary applications like Drive, Photos, and Active Backup. For Plex and Jellyfin, hardware transcoding is supported via the Intel Quick Sync engine integrated into the CPU, although efficiency is slightly lower than that of recent Intel chips. Docker installation is native and very well integrated, facilitating container management via Portainer. However, the lack of a native 2.5GbE port (only Gigabit) is a hindrance for fast transfers, and the price of RAM upgrades and Synology drives is often higher. It is the choice of peace of mind, ideal for a beginner who wants things to "just work" without tinkering.

UGREEN NASync DXP2800

The UGREEN DXP2800 represents the new wave of Chinese manufacturers offering high-performance hardware at a competitive price. It features an Intel N100 processor (4 cores, 3.4 GHz), a chip much more powerful than traditional ARM chips, offering superior raw performance to the DS224+ for computing and virtualization. It comes with 8 GB of soldered DDR5 RAM, which is more than enough to run many Docker services without issues, although the non-expandability is a risk if your needs explode. The operating system, UGOS (based on Linux), is in full maturity. It offers a modern interface and natively supports Docker and virtualization applications, although the community is smaller than Synology's. The strong point is the excellent hardware transcoding thanks to the Intel Quick Sync in the N100 series, capable of easily handling multiple 4K streams. Connectivity often includes 2.5GbE ports, which is a major advantage for the local network. The main drawback lies in software longevity and the potential complexity of restoration after a crash compared to DSM. It is an excellent choice for the homelabber who wants raw power and accepts testing a less polished OS.

QNAP TS-264

The QNAP TS-264 positions itself as the Swiss Army knife of the homelab. It is powered by an Intel Celeron N5105 quad-core processor, accompanied by 4 GB of DDR4 RAM expandable up to 16 GB via two slots. This RAM expandability is a decisive asset for advanced users. The QTS operating system is powerful but can seem cluttered and less intuitive than DSM for a beginner. However, it offers advanced virtualization features with QNAP Virtualization Station, allowing you to run virtual machines (Proxmox, Ubuntu) directly on the NAS, which is out of reach for the other models in this range. For Docker, QNAP supports Container Station, which is functional but sometimes less smooth than the Synology offering. Hardware transcoding is also very good thanks to Intel Quick Sync. The TS-264 features 2.5GbE ports and several USB 3.2 ports, facilitating the addition of external drives or license keys. It is the ideal choice for the intermediate user who wants to extend their homelab towards lightweight virtualization while keeping direct access to the file system.

Use cases

For the Absolute Beginner profile who just wants to back up photos and watch movies without touching the console, the Synology DS224+ is the safest choice. The user experience is unmatched, and the learning curve is virtually non-existent. If you have a tight budget but need power, the UGREEN DXP2800 offers a better price/performance ratio thanks to its N100, provided you accept an OS in development. For the Intermediate Homelabber profile who wants to run Home Assistant, a file server, and perhaps a lightweight VM, the QNAP TS-264 is the most versatile thanks to its expandable RAM and virtualization capabilities. The UGREEN remains a serious candidate if you prefer the x86 architecture for software compatibility, but the soldered RAM may limit future evolution.

Traps to avoid

The most common trap is underestimating RAM. Buying a NAS with 2 GB of RAM to install Plex and Docker is a mistake. The system will use swap on the disk, slowing everything down and prematurely wearing out the storage. Always plan for a RAM upgrade if possible. Another trap is neglecting network connectivity. If your ISP offers more than 100 Mbps, Gigabit Ethernet will be a bottleneck. Prioritize 2.5GbE models. Finally, beware of "kits" sold with cheap hard drives. NAS drives (such as WD Red Plus or Seagate IronWolf) are designed to run 24/7 and are more reliable than standard PC drives. Also check the warranty and technical support, especially for less established brands like UGREEN, whose after-sales service may be slower than that of Synology or QNAP.

Verdict

There is no "best" universal NAS, but rather the best NAS for your skill level and future needs. The Synology DS224+ wins on reliability and ecosystem, perfect for those who want a tool that disappears behind its function. The QNAP TS-264 is the king of hardware and software flexibility, ideal for those who want to learn and expand their infrastructure. The UGREEN DXP2800 is the surprise of the year, offering modern x86 performance at a price that defies competition, but at the cost of software that is still imperfect. For most homelab beginners in 2026, Synology remains the default choice for peace of mind, while more technical users will turn to QNAP or UGREEN for raw power. Whatever your choice, make sure to set up RAID 1 from the start and plan off-site backups, because a NAS is not a backup; it is storage.
