Pros
- Budget-friendly at $409
- 4-bay NAS with 2.5GbE
- Best entry point for NAS beginners
- Good for basic home file storage
- Time Machine and NetBak Replicator support
Cons
- ARM processor less powerful than Intel/AMD
- No M.2 NVMe slots
- Only 2-year warranty
- No hardware transcoding support
The QNAP TS-433-4G-US earns my Budget Pick designation as the most accessible entry point into the world of QNAP 4-bay NAS storage at just $409. While the ARM Cortex-A55 quad-core processor and 4GB of DDR4 RAM represent more modest specifications compared to Intel and AMD alternatives, this NAS still provides all the essential features most home users need. In testing, the TS-433-4G-US handled basic file sharing, automated backups, and single-user media streaming without any issues.
One limitation worth noting is the absence of M.2 SSD slots, which means you cannot add caching acceleration or create SSD storage pools. For users with large media libraries requiring frequent random access to many small files, this could impact performance. However, for primary use cases like storing and streaming complete video files, music collections, or photo archives, the traditional hard drive configuration works perfectly well. The 2.5GbE port still provides meaningfully faster network speeds compared to traditional Gigabit Ethernet, ensuring smooth transfers within your local network.
The inclusion of both 2.5GbE and Gigabit Ethernet ports is generous at this price point. Even without M.2 caching, sequential file transfers reached 280 MB per second over 2.5GbE in testing. For first-time NAS buyers or families needing central photo storage, this budget-friendly option accomplishes everything needed without overwhelming complexity.
Who Should Buy This NAS?
This NAS is perfect for first-time NAS buyers or households with basic storage requirements. If your primary goals involve centralizing family files, setting up automated backups from computers and mobile devices, and streaming multimedia content to a single location, the TS-433-4G-US accomplishes all of this at an attractive price point. The ARM processor’s lower power consumption also makes this model more energy-efficient for users who plan to run their NAS continuously. Just keep in mind that if you eventually outgrow its capabilities, you will need to migrate to a more powerful model rather than upgrading components.
Key Specifications
- ARM Cortex-A55 Quad-core 2.0GHz
- 4GB DDR4 RAM
- 4-bay configuration
- 2.5GbE + 1GbE dual network ports
- USB 3.2 Gen 2 (up to 10Gb/s)

Buying Guide: How to Choose the Best QNAP 4-Bay NAS in 2026?
Selecting the right QNAP 4-bay NAS requires careful consideration of several factors that will impact your storage experience for years to come. Below, I break down the key decision points to help you match your requirements with the ideal model.
Processor Architecture: Intel, AMD, or ARM?
The processor determines how quickly your NAS can handle simultaneous requests, transcode media files, run applications, and manage data transfers. Intel Celeron processors found in models like the TS-464 and TS-453E offer an excellent balance of performance and power efficiency, with quad-core configurations handling most home and small business workloads admirably. The AMD Ryzen V1500B in the TS-473A provides superior CPU performance for demanding applications like virtual machines and intensive transcoding. ARM-based processors like the Cortex-A55 in the TS-433 sacrifice some computational power for lower cost and energy consumption, making them suitable for basic storage tasks.
Memory and Expandability
RAM capacity directly impacts how many applications and services your NAS can run simultaneously. The TS-464, TS-453E, and TS-473A all ship with 8GB, which handles simultaneous file sharing, Plex streaming, Docker containers, and surveillance stations without breaking a sweat. If you plan to run virtual machines or memory-intensive applications, consider the TS-473A with its 64GB maximum expansion capacity. The TS-433’s 4GB suffices for basic operations but may limit your ability to run multiple advanced features concurrently.
Storage Configuration and M.2 SSD Slots
Dual M.2 PCIe SSD slots on the TS-464, TS-453E, TS-473A, and TVS-h474 enable several advanced configurations. SSD caching stores frequently accessed data on fast solid-state drives for near-instantaneous retrieval while maintaining the large capacity of traditional hard drives for archival storage. Alternatively, you can create a dedicated SSD storage pool for applications requiring high IOPS performance. The TS-433 lacks this expansion capability, so all storage must rely on traditional hard disk drives.
Network Connectivity
All five QNAP 4-bay NAS systems in this guide feature at least one 2.5GbE port, providing 2.5 times the bandwidth of standard Gigabit Ethernet. This proves essential for users transferring large media files, running multiple simultaneous streams, or accessing the NAS from multiple devices at once. The TS-464, TS-453E, TS-473A, and TVS-h474 all include dual 2.5GbE ports that can be aggregated for 5Gbps throughput or used for separate network segments. If you have a modern router and compatible client devices, these faster network ports will noticeably improve your experience.
RAID Configurations and Data Protection
With four drive bays, you can configure various RAID levels to balance capacity and redundancy. RAID 5 provides the best balance, offering usable capacity equal to three drives while protecting against a single drive failure. RAID 6 adds a second parity drive, allowing survival of two simultaneous drive failures at the cost of two drives’ worth of capacity. RAID 10 combines performance and protection but requires half your total capacity. QNAP’s QTS operating system makes RAID configuration straightforward through its web-based interface, and features like snapshot backup and HBS 3 hybrid backup provide additional data protection options.
Special Features to Consider
The TVS-h474-PT-8G-US stands out with its HDMI output, allowing direct connection to a television or monitor for 4K media playback without network streaming. This makes it an excellent choice for home theater enthusiasts who want a dedicated media player alongside their storage. The TS-473A’s support for Google Workspace and Microsoft 365 backup addresses business users’ needs for SaaS data protection. Consider which features align with your specific use case before making your final decision.
