Verdict
The QNAP TS-233 earns a solid 3 stars. Competent at its stated purpose, constrained by design choices that limit longevity. The QNAP TS-233 has a market price of about $402 and is a legitimate budget 2-bay NAS for straightforward file sharing and backup. The TS-233 uses a 2.0GHz ARM Cortex-A55 processor, whereas the DS223 and DS223j use a 1.7GHz Realtek RTD1619B and the DS225+ uses an Intel Celeron J4125; the TS-233 also has 1GbE networking and non-upgradeable RAM.
For most Australian households, spending more for the Synology DS225+, which has a market price of about $599, is the better long-term decision. The 2.5GbE network, RAM upgrade path, and Synology Photos ecosystem justify the premium. The TS-233 is the right choice when budget is genuinely the binding constraint and the use case is strictly file storage and backup with no interest in photos or Docker.

Compare all current QNAP NAS models available in Australia, from entry-level to enterprise, with AU pricing.
The QNAP TS-233 is a capable entry-level 2-bay NAS for file sharing and backup, but its ARM processor and 1GbE networking mean you’ll outgrow it quickly if your needs extend to Docker, Plex transcoding, or fast local transfers. The QNAP TS-233 has a market price of about $402; compare current Australian retailer prices before purchasing. And the comparison matters, because which brand you choose at this level shapes your ecosystem for years.

What the TS-233 Does Well
At its price point, the TS-233 does the basics reliably. The TS-233 supports SMB and AFP file sharing; actual performance depends on the drives, workload, network and concurrent activity. QTS, QNAP’s operating system, is available in full, including the same web interface as higher-end QNAP units. You get QNAP’s myQNAPcloud for remote access, snapshot support, and all standard NAS protocols at a price that undercuts many competitors.
The TS-233 supports the following use cases:
- File server for a home or small office with 1-2 concurrent users
- Time Machine destination for Mac backups (AFP)
- Personal cloud with QNAP’s myQNAPcloud relay
- USB backup to an attached external drive
- Basic photo management via QNAP’s QuMagie (limited compared to Synology Photos)
- Scheduled backup jobs via Hybrid Backup Sync
The Limitations You Need to Know
The TS-233’s constraints are more significant than its spec sheet suggests. Three stand out for Australian buyers:
ARM architecture limits Docker. Like Synology’s entry ARM units, the TS-233 can run Docker containers via Container Station, but only ARM-compatible images. Some Docker Hub images may not provide an ARM64 variant, so check each image’s supported architectures. If Docker is on your list, the TS-264’s x86 N5095 processor is a meaningful step up.
1GbE is the ceiling. The TS-233 has a single Gigabit Ethernet port. That’s 125 MB/s theoretical throughput, more like 100-115 MB/s in practice. For a single drive sequential read, you’ll saturate the network before you saturate the drive. This is fine for most backup and cloud-sync workflows, but video editors, photographers, and anyone moving large files regularly will feel the constraint. The TS-264 has two 2.5GbE ports, providing up to five times the TS-233’s raw aggregate link capacity when both links are used with port trunking and suitable network infrastructure.
RAM is capped at 2GB. The TS-233 ships with 2GB and has no user-accessible RAM slot for expansion. The TS-233 has 2GB of non-expandable RAM; performance while running apps or containers alongside file serving depends on their memory and CPU demands. Synology’s DS225+ also ships with 2GB but supports a user-installed upgrade to 6GB total.
TS-233 vs DS225+. Which Entry-Level 2-Bay Should You Buy?
QNAP TS-233 vs Synology DS225+. Entry 2-Bay Comparison (AU)
| QNAP TS-233 | Synology DS225+ | |
|---|---|---|
| AU market price | about $402 | about $599 |
| Cheapest AU listing | $369 (Computer & Parts Land) | $565 (CCPU Computers) |
| CPU | ARM Cortex-A55 2.0 GHz processor | Intel Celeron J4125 (4-core) |
| RAM (base) | 2GB (non-upgradeable) | 2GB (upgradeable to 6GB) |
| Network | 1x 1GbE | 1x 2.5GbE + 1x 1GbE |
| M.2 slots | Not included | Not included |
| Operating system | QTS | DSM 7 |
| Docker | ARM only (Container Station) | x86-64/amd64 (Container Manager) |
| Photo app | QuMagie (basic) | Synology Photos (excellent) |
The Synology DS225+ has a market price of about $599. The QNAP TS-233 has a market price of about $402. What that premium buys you: 2.5GbE networking (2.5x the nominal link rate of 1GbE; actual transfer speeds vary), a RAM upgrade path to 6GB, and Synology’s significantly better first-party app ecosystem. Particularly Synology Photos, which is far more polished than QNAP’s QuMagie at this level.
If budget is genuinely tight and you need a 2-bay NAS for file sharing and backup only, the QNAP TS-233 at a market price of about $402 is a legitimate option. If you have even a moderate chance of wanting photo management, 2.5GbE, or better software integration, the DS225+ is the better investment. See our DS225+ vs TS-264 comparison if you’re considering stepping up to x86.
Australian Pricing and CGNAT
The QNAP TS-233 has a market price of about $394, and the cheapest TS-233 listing is $369 (Computer & Parts Land). Compare current Australian retailer prices before purchasing. The TS-233 has a two-year standard QNAP warranty. QNAP lists both Bluechip Infotech and Dicker Data as Australian distributors; confirm warranty handling with the retailer. See our full guide on where to buy NAS in Australia.
For remote access on CGNAT (used by Aussie Broadband and some other NBN providers), the TS-233 supports myQNAPcloud relay, QNAP’s cloud relay service that works without port forwarding. It’s functional, though QNAP notes that the relay may be slow during peak usage. For households on CGNAT who want low-friction remote access, the DSM ecosystem has a slight edge here. Our CGNAT and NAS remote access guide covers workarounds for both platforms.
Pros

How much does the QNAP TS-233 cost in Australia?
The QNAP TS-233 has a market price of about $394, and the cheapest TS-233 listing is $369 (Computer & Parts Land). Retailer pricing and promotions vary, so compare current Australian listings before purchasing. The TS-233 is sold diskless, so hard drives need to be purchased separately.
Can the QNAP TS-233 run Docker containers?
Yes, via Container Station, but with limitations. The TS-233 uses an ARM Cortex-A55 processor, meaning only ARM-compatible Docker images will run. Some Docker Hub images do not provide an ARM64 variant; verify the supported architectures for each required image. For broader x86-64 Docker image compatibility, the QNAP TS-264 has a market price of about $999. The QNAP TS-233 has a market price of about $402.
Is the QNAP TS-233 better than the Synology DS220+?
The DS220+ has been superseded by the DS225+ in Synology’s lineup. Comparing the current models, the QNAP TS-233 has a market price of about $399. The Synology DS225+ has a market price of about $599 and offers 2.5GbE rather than 1GbE, an upgradeable RAM path, and a more polished photo management app. For most households, the DS225+ is the better value despite its higher price.
Does the QNAP TS-233 work on CGNAT in Australia?
Yes. The TS-233 supports QNAP’s myQNAPcloud relay, which routes remote access through QNAP’s servers and does not require port forwarding. This works on CGNAT connections, including default residential Aussie Broadband services; CGNAT use varies by provider and service type. The relay is functional but less consistent than Synology’s QuickConnect equivalent.
Is the QNAP TS-233 suitable for Plex Media Server?
For Plex, the TS-233 supports direct play and software transcoding of SD and 720p content; Plex rates 1080p software transcoding as partial and 4K transcoding as unsupported. Plex hardware-accelerated transcoding is not supported on this model. For a Plex NAS, the QNAP TS-264 with Intel Quick Sync is the minimum recommendation.
