I have been running the TS-464 in my home lab for eight months now, and it has become my go-to recommendation for anyone stepping into the NAS world. The Intel Celeron N5105 processor delivers enough muscle for file sharing, backups, and light media duties without the premium price of higher-end units.
The dual 2.5GbE ports were the first thing I tested. Moving from a gigabit NAS to this felt like upgrading from a country road to a highway. File transfers that used to crawl at 110 MB/s now blast at 280 MB/s with link aggregation enabled. For anyone working with large video files or RAW photo libraries, this speed difference changes everything.
What impressed me most was the M.2 NVMe slots. I popped in two 1TB SSDs and configured them as a read cache. My frequently accessed files now load instantly, while the spinning drives handle bulk storage. It is the best of both worlds without breaking the bank.
The QTS operating system deserves special mention. Yes, it has a learning curve compared to Synology DSM, but once you understand the layout, it offers more granular control. I spent about two hours on initial setup including RAID 5 configuration and user permissions. The included apps for backup, sync, and media management cover 95% of what home users need.
There are limitations. When I tried streaming 4K HDR content to three devices simultaneously, the CPU started choking. For serious Plex media streaming with transcoding, you will want a more powerful unit. But for direct-play scenarios or single-stream transcoding, it handles itself well.
Who Should Buy This
The TS-464 hits the sweet spot for home users and small offices that need reliable storage with room to grow. If you want 2.5GbE networking, NVMe caching, and a processor that handles everyday tasks without breaking a sweat, this is your unit.
Photographers and content creators working with large file sets will appreciate the speed. Small business owners get enterprise-grade backup features without enterprise pricing. Just do not expect it to transcode multiple 4K streams simultaneously.
Who Should Skip This
Power users planning heavy virtualization workloads or multi-user 4K transcoding should look at the TS-473A or TVS-h474 instead. The Celeron processor has limits. If you need 10GbE networking out of the box, you will need to add an expansion card via the PCIe slot.
Budget-conscious buyers might prefer the TS-433 for pure storage tasks. The TS-464 sits in a middle ground that suits most people but not everyone.

How to Choose the Right QNAP 4-Bay NAS
Selecting the right NAS comes down to matching your actual needs against hardware capabilities. After helping dozens of readers choose their first NAS, I have identified the key decision points that matter most.
Processor Selection: Intel vs ARM
The processor determines what your NAS can actually do. Intel Celeron and Pentium processors found in the TS-464, TS-453E, and TVS-h474 run full QTS applications, support hardware transcoding, and handle virtualization. The ARM processor in the TS-433 works fine for file storage but struggles with demanding apps.
For basic backups and file sharing, the ARM-based TS-433 suffices and saves money. For media streaming, Docker containers, or anything beyond storage, choose Intel. Power users needing virtualization should consider the AMD Ryzen in the TS-473A or the Pentium Gold in the TVS-h474.
Network Speed: Gigabit vs 2.5GbE
All models in this guide except the TR-004 include 2.5GbE networking. If your router and computers still run gigabit, the upgrade benefits remain theoretical. However, 2.5GbE equipment costs nearly the same as gigabit now, making future-proofing sensible.
Link aggregation lets you combine both 2.5GbE ports for up to 5 Gbps with compatible switches. This matters for multi-user environments where several people access the NAS simultaneously. Single users will not see benefits beyond a single 2.5GbE connection.
RAID Configuration Guidance
Four drive bays unlock serious RAID configurations for data protection. RAID 5 uses one drive for parity, giving you the capacity of three drives with single-drive failure protection. RAID 6 uses two parity drives, allowing dual-drive failure protection with the capacity of two drives.
For most home users, RAID 5 offers the best balance. You get protection against a single drive failure without sacrificing too much capacity. Business users or those storing irreplaceable data should consider RAID 6 for the extra safety margin. Never run RAID 0 on important data; one failure loses everything.
RAM and Upgrade Path
Base RAM configurations range from 4GB to 8GB across these models. For pure storage, 4GB works. For running apps, containers, or media servers, 8GB provides breathing room. The TS-464, TVS-h474, and TS-473A allow RAM upgrades to 16GB or 64GB for demanding workloads.
Consider your five-year needs, not just today. A NAS should last through multiple upgrade cycles. Paying slightly more for expandable RAM often saves money long-term versus replacing an entire unit.
Use Case Matching
Match your primary use case to the right hardware. Pure storage and backups suit the TS-433. Media streaming with occasional transcoding works on the TS-464. Heavy virtualization and business applications need the TVS-h474 or TS-473A. Silent operation demands the TBS-464. Choose appropriate drives to match your NAS investment.
