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. At $399 (PLE) to $487 (Mwave), it competes directly with Synology’s entry lineup on price. 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. File sharing via SMB and AFP works well for small households with 1-2 simultaneous users. 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 handles the following use cases without issues:
- 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. Many Docker Hub images are x86-only. Popular self-hosted tools like some monitoring stacks, certain media management apps, and various developer tools publish ARM images that lag behind in updates. 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 anyone moving large files regularly. Video editors, photographers. Will feel the constraint. The TS-264’s dual 2.5GbE is five times the bandwidth.
RAM is capped at 2GB. The TS-233 ships with 2GB and has no user-accessible RAM slot for expansion. QTS runs on 2GB without issues for basic NAS tasks, but running multiple apps or containers alongside file serving will cause slowdowns. 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+ | |
|---|---|---|
| None | $399-$487 | $585-$599 |
| None | Arm Cortex-A55 (4-core) | Arm Cortex-A55 (4-core) |
| None | 2GB (non-upgradeable) | 2GB (upgradeable to 6GB) |
| None | 1x 1GbE | 1x 2.5GbE |
| None | None | None |
| None | QTS | DSM 7 |
| None | ARM only (Container Station) | ARM only (Container Manager) |
| None | QuMagie (basic) | Synology Photos (excellent) |
| None | $186-$200 cheaper | - |
The DS225+ costs $186-$200 more than the TS-233 at PLE. What that premium buys you: 2.5GbE networking (2.5x faster), 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 TS-233 at $399 from PLE 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 TS-233 shows unusual price variation between retailers: $399 at PLE, $439 at Scorptec, and $486.95 at Mwave. Always check PLE Computers first for QNAP in Australia. They consistently carry the most competitive QNAP pricing. QNAP is distributed through Dicker Data in Australia, so warranty support is the same regardless of which AU retailer you purchase from. See our full guide on where to buy NAS in Australia.
For remote access on CGNAT (common on Aussie Broadband, TPG, and other NBN resellers), the TS-233 supports myQNAPcloud relay. QNAP’s cloud relay service that works without port forwarding. It’s functional but less reliable than Synology’s QuickConnect. 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
- Lowest price for a QNAP 2-bay in Australia. $399 at PLE
- Full QTS operating system. Same interface as pricier QNAP units
- Hot-swappable drive bays at this price point
- myQNAPcloud relay for remote access (works on CGNAT)
- Low power draw. ~12W operating, quiet operation
- 2-year warranty via Dicker Data AU
Cons
- ARM processor. Docker compatibility limited to ARM images
- 1GbE only. No 2.5GbE, no upgrade path
- 2GB RAM non-upgradeable. Hard ceiling
- No M.2 slots for SSD cache
- QuMagie photo app is basic compared to Synology Photos
- Significant price variation between retailers (check PLE first)
Verdict
The QNAP TS-233 earns a solid 3 stars. Competent at its stated purpose, constrained by design choices that limit longevity. At $399 from PLE it’s a legitimate budget 2-bay NAS for straightforward file sharing and backup. The same CPU as Synology’s entry units but with 1GbE networking and a non-upgradeable RAM cap means you’re trading network performance and flexibility for a lower entry price.
For most Australian households, spending the extra $186-$200 for the Synology DS225+ 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.

How much does the QNAP TS-233 cost in Australia?
The QNAP TS-233 is priced at $399 at PLE Computers, $439 at Scorptec, and $486.95 at Mwave. PLE consistently has the best QNAP pricing in Australia. It is sold diskless. You need to add hard drives separately. Two 4TB Seagate IronWolf drives add approximately $260, bringing the fully-equipped cost to around $659-$749.
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. Many popular Docker Hub images are x86-only. For full Docker compatibility without architecture restrictions, the QNAP TS-264 (Intel x86) is a better choice, though it costs approximately $420-$518 more in Australia.
Is the QNAP TS-233 better than the Synology DS220+?
The DS220+ has been superseded by the DS225+ in Synology’s lineup. Comparing the TS-233 to the current DS225+: the TS-233 is $186-$200 cheaper at PLE but has 1GbE networking versus the DS225+’s 2.5GbE, a non-upgradeable RAM cap, and a less 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 (common on Aussie Broadband, TPG, and other NBN resellers). The relay is functional but less consistent than Synology’s QuickConnect equivalent.
Is the QNAP TS-233 suitable for Plex Media Server?
Only for direct play. The TS-233’s ARM processor has no hardware transcoding capability and is too slow for software transcoding of 1080p or 4K content. It can serve media files to Plex clients that natively support the codec (direct play), but any client requiring transcoding will result in buffering or playback failure. For a Plex NAS, the QNAP TS-264 with Intel Quick Sync is the minimum recommendation.
