**A 2-bay NAS (network-attached storage device) is a popular form factor for Australian home users and small offices for good reason: it hits the sweet spot of price, redundancy, and physical size for home users and small offices.** Two drive bays give you RAID 1 (a way of mirroring data across drives so it survives a single drive failure) mirroring for data protection, raw capacity that depends on the drives you install and the NAS's compatibility list, and a compact footprint that sits comfortably on a desk or shelf. In 2026, the Synology DS124 has a market price of about $255. The Synology DS225+ has a market price of about $599. The right choice depends entirely on what you plan to do with it. And whether you value software polish, raw performance, or the lowest possible price.

> **Note:** **In short:** The **Synology** (one of the leading NAS brands) **DS225+** (about $599) is the best 2-bay NAS in Australia for most buyers. Proven software and 2.5GbE networking. For budget buyers, the **QNAP TS-233** (about $402) delivers solid file storage at a low price. The **Asustor AS5402T** (about $545) is the pick for Plex (a popular media server app) and media enthusiasts thanks to its HDMI output and dual 2.5GbE ports. And if you just need basic backup on a tight budget, the **Synology DS124** starts at $239 (Computer & Parts Land, Computer Alliance, MSY, UMart). Though it is a 1-bay unit and cannot run RAID.

## Why a 2-Bay NAS?

A 2-bay NAS is the entry point for proper data redundancy. With two drives configured in [RAID 1 (mirroring)](/blog/nas-raid-explained/), your data survives a single drive failure. Something that is impossible with a 1-bay unit. For most home users storing photos, documents, and media files, a 2-bay NAS provides more than enough capacity. Two 8TB drives in RAID 1 give you 8TB of usable, protected storage. And if that sounds small, consider how much data your own household currently stores and expects to add.

The 2-bay form factor also keeps the total cost of ownership down. You are buying two drives instead of four, the NAS enclosure itself costs less than a 4-bay, and power consumption stays low. Vendor power figures for the 2-bay models in this guide run from 10.69 W (Synology DS124, drive access) to 22.9 W (Asustor AS5402T, operation). For a device that runs 24/7, that power difference adds up over years. If you are exploring whether a NAS makes sense for your setup, our [best NAS for home guide](/blog/best-nas-for-home-australia/) covers the broader decision in detail.

That said, a 2-bay NAS has a hard ceiling on expandability. You cannot add more drives later without replacing the unit entirely (unless you buy an expansion unit, which only some models support and at significant cost). If you think you might need more than two bays in the next 3-5 years, a 4-bay NAS is the better starting point. Even if you only populate two bays initially. Our [main NAS buying guide](/blog/best-nas-australia/) compares across all form factors.

All prices are in AUD and are Australian market prices unless a retailer is named. These are diskless prices. You will need to budget separately for [NAS-rated hard drives](/blog/best-nas-hard-drive-australia/), and drive prices have risen noticeably from early 2025 levels, so check current capacity-specific pricing before budgeting.

## Synology DS225+. Best Overall 2-Bay NAS

The Synology DS225+ is the clear pick for most Australian buyers looking for a 2-bay NAS in 2026. It replaces the DS224+ and adds a 2.5GbE port alongside the standard 1GbE port. The DS225+ has no M.2 slots, so SSD caching requires compatible SATA SSDs in its two main drive bays. The J4125 includes Intel Quick Sync, but Plex hardware transcoding is not officially supported on the DS225+. The DS225+ runs DiskStation Manager (DSM), which remains the most polished NAS operating system available: intuitive enough for first-time users while deep enough for advanced deployments.

The Synology DS225+ has a market price of about $599 and sits at a premium over budget 2-bay options. That premium buys you the [Synology ecosystem](/blog/synology-nas-australia/). Synology Photos for Google Photos-style photo management, Synology Drive for Dropbox-like file sync, Active Backup for Business for PC and server backup, and Hyper Backup for versioned offsite backup. Availability varies by model: Photos, Drive, and Hyper Backup support the DS124, while Active Backup for Business requires a compatible x64 Btrfs model such as the DS225+.

The 2.5GbE port is a genuine upgrade over the discontinued DS224+. If your router or switch supports 2.5GbE, you will see real-world file transfer speeds around 280MB/s. Roughly 2.5 times faster than gigabit. Even without 2.5GbE infrastructure today, it future-proofs the unit for when you upgrade your network.

For Australian buyers on NBN, the DS225+ also handles remote access well through Synology's QuickConnect relay service. Particularly useful if your NBN connection uses CGNAT (depending on your ISP and service configuration), which blocks traditional port forwarding. Remote access performance is constrained by your NBN upload speed regardless of the NAS. Upload speed depends on access technology and plan: current examples include up to 20Mbps on Home Fast I or Fixed Wireless Plus and 50Mbps on eligible FTTP/HFC Home Fast II services, which means remote access to large files will be slow. But for syncing documents and viewing photos remotely, QuickConnect works well enough.

- **AU market price:** about $599
- **Cheapest AU listing:** $565 (CCPU Computers)
- **Maximum raw capacity:** Up to 48TB

**Pros**
- DSM is the best NAS operating system available. Intuitive, reliable, regularly updated
- Intel J4125 runs a Plex server for direct play (Plex hardware transcoding is not officially supported on the DS225+)
- 2.5GbE port. Genuine speed upgrade and future-proofing
- Up to 48TB of raw capacity across its two bays
- Strong app ecosystem: Synology Photos, Drive, Active Backup, Surveillance Station
- QuickConnect bypasses CGNAT for remote access on difficult NBN connections

**Cons**
- 2GB RAM is tight. Upgrade to 6GB recommended for Docker or heavy multitasking
- No HDMI output. Cannot connect directly to a TV
- Premium price compared to ARM-based 2-bay alternatives
- No M.2 slots. SSD caching uses one of the two drive bays
- RAM upgrade requires opening the unit. Not user-friendly for beginners

## Synology DS224+: Discontinued, Buy the DS225+

The Synology DS224+ is discontinued and no longer listed by Australian retailers. The DS225+ replaces it with the same Intel Celeron J4125 processor and DSM software, plus a 2.5GbE port, so it is the model to buy instead.

*Synology DiskStation DS225+ on Amazon AU*

## QNAP TS-233. Best Budget 2-Bay NAS

The QNAP TS-233 is the go-to budget 2-bay NAS in Australia for buyers who want reliable networked storage without paying Plus-series prices. The QNAP TS-233 has a market price of about $402. The Synology DS225+ has a market price of about $599, so the QNAP costs less and leaves more of the budget for hard drives. The trade-off is clear: The TS-233 includes QNAP-supported hardware-accelerated transcoding, but Plex lists no Plex hardware transcoding for it and software transcoding only up to 720p (some 1080p), and you get QNAP's QTS operating system instead of Synology's DSM.

For file storage, backup, and basic media streaming (direct play, not transcoding), the TS-233 handles the workload without issue. The ARM Cortex-A55 quad-core CPU and 2GB RAM are adequate for SMB file sharing across a home network, running QNAP's own backup applications, and serving media files to devices that can play them natively. It will not transcode 4K video on the fly for Plex. If that matters, look at the Asustor AS5402T or another model on Plex's supported NAS list.

QTS is a capable operating system, but it has a steeper learning curve than DSM. QNAP's interface has more options exposed to the user, which is powerful for experienced users but can be overwhelming for beginners. QNAP also has a more troubled security history than Synology. There have been several high-profile ransomware incidents targeting QNAP devices. This does not mean the TS-233 is unsafe, but it does mean staying on top of firmware updates and following [QNAP's security best practices](/blog/qnap-nas-australia/) is essential. For a broader look at the brand and its strengths, see our [QNAP NAS Australia guide](/blog/qnap-nas-australia/).

*QNAP TS-233 on Amazon AU*

- **CPU:** ARM Cortex-A55 Quad-Core, 2.0GHz
- **RAM:** 2GB DDR4 (not expandable)
- **Drive Bays:** 2x 3.5"/2.5" SATA
- **M.2 Slots:** Not included
- **Network:** 1x 1GbE RJ45
- **USB:** 1x USB 3.2 Gen 1, 2x USB 2.0
- **Hardware Transcode:** No
- **Power Consumption:** 10.81 W (Operating Mode, Typical, per QNAP; tested with drives fully populated)
- **Warranty:** 2 years
- **AU market price:** about $402
- **Cheapest AU listing:** $369 (Computer & Parts Land)
- **Expansion:** QNAP TR-002 / TR-004 USB expansion units

**Pros**
- A relatively inexpensive major-vendor option, but not currently the lowest-priced name-brand two-bay NAS in Australia.
- Solid for file storage, backup, and direct-play media streaming
- Low power consumption. QNAP rates typical operation at 10.81 W, tested with drives fully populated
- QNAP's app ecosystem includes Hybrid Backup Sync, QuMagie photo management, and Container Station
- Compact form factor

**Cons**
- ARM CPU. No hardware transcoding for Plex or video apps
- Only 1GbE networking. Capped at ~115MB/s file transfers
- RAM is fixed at 2GB and cannot be upgraded
- QTS has a steeper learning curve than Synology DSM
- QNAP has a more troubled security history. Firmware updates are essential
- Only 2-year warranty (compared to 3 years for Synology)

## Asustor AS5402T. Best for Media and Plex

The Asustor AS5402T (Nimbustor 2 Gen2) is the 2-bay NAS to buy if media playback and Plex are your primary use cases. It packs an Intel Celeron N5105 quad-core processor with Intel UHD graphics, 4GB of DDR4 RAM, dual 2.5GbE ports, four M.2 NVMe 2280 slots and, critically, an HDMI 2.0b output that can drive a 4K display directly. No other 2-bay NAS in this price range offers that combination.

The N5105 supports hardware-accelerated 4K transcoding, but Plex performance depends on the source format, bitrate, subtitles, client and an active Plex Pass. The 4GB of RAM (upgradeable to 16GB) gives significantly more headroom for Docker containers, virtual machines, and multitasking than the 2GB found in the Synology Plus series. The dual 2.5GbE ports support link aggregation for up to 5Gbps aggregate throughput, or can be used independently for traffic separation.

The trade-off is software. Asustor's ADM (ASUSTOR Data Master) is functional but does not match DSM's polish or app ecosystem depth. Asustor has a smaller community, fewer third-party guides, and less mature mobile apps. If you are a first-time NAS buyer, the learning curve is steeper than Synology. But if you know what you want, a powerful media server with HDMI output and strong hardware, the AS5402T delivers more hardware per dollar than anything Synology offers at this bay count. For more on the brand, see our [Asustor NAS Australia guide](/blog/asustor-nas-australia/).

Pricing varies significantly across Australian retailers. The AS5402T sells for about $545. The size of the spread changes with live retailer pricing. Well worth shopping around. If you are considering the AS5402T for Plex specifically, our [best NAS for Plex guide](/blog/best-nas-for-plex-australia/) includes detailed transcoding benchmarks and comparisons.

*[Asustor Nimbustor 2 AS5402T on Amazon AU](https://www.amazon.com.au/dp/B0C5MB5MTS?tag=ntkit-22)*

- **CPU:** Intel Celeron N5105, 4-core, 2.0GHz (burst 2.9GHz)

- **Drive Bays:** 2x 3.5"/2.5" SATA
- **M.2 Slots:** 4x NVMe (2280)
- **Network:** 2x 2.5GbE RJ45
- **USB:** 3x USB 3.2 Gen 2 Type-A
- **HDMI:** 1x HDMI 2.0b (4K@60Hz)
- **Hardware Transcode:** Yes (Intel UHD Graphics)
- **Power Consumption:** 22.9 W (Operation, per ASUSTOR)
- **Warranty:** 3 years
- **AU market price:** about $545
- **Cheapest AU listing:** Check current listings
- **Expansion:** Asustor AS6004U / AS5004U expansion units (up to 3)

**Pros**
- HDMI 2.0b output. Connect directly to a TV for 4K media playback
- Intel N5105 handles Plex hardware transcoding including 4K HEVC
- 4GB RAM, expandable to 16GB; the DXP2800 GT starts with 8GB and supports up to 64GB.
- Dual 2.5GbE ports with link aggregation support
- Four M.2 NVMe slots for SSD caching or storage

**Cons**
- ADM software is less polished than Synology DSM
- Smaller community and fewer third-party guides than Synology
- Mobile apps are less refined than Synology's
- Higher power consumption than ARM-based alternatives
- Asustor's market share is small. Fewer accessories and ecosystem integrations
- Retailer prices vary widely, so compare before buying

## Synology DS124. Best Ultra-Budget Entry Point

The Synology DS124 is technically a 1-bay NAS, not a 2-bay. But it earns a place in this guide because it is the cheapest way into the Synology ecosystem and is often the starting point for buyers exploring NAS for the first time. The Synology DS124 has a market price of about $266 and costs less than many external hard drives while offering networked access, automated backup, and Synology's full DSM software suite.

**Still deciding?: Synology DS225+**
Our top pick: Synology DS225+.
[Check price](https://www.amazon.com.au/dp/B0FC2888KF?tag=ntkit-22)

The critical limitation: with one drive bay, there is no RAID redundancy. If the single drive fails, your data is gone unless you have another backup. This makes the DS124 unsuitable as a primary storage device unless it is part of a broader backup strategy. Use it as a backup target for laptops and phones (via Synology Drive), a remote-accessible file store, or a low-cost cloud replacement for document sync. But do not treat it as your only copy of anything important.

The Realtek RTD1619B processor and 1GB RAM are enough for file operations, Synology Photos with a modest library, and basic cloud sync. It will not run Docker, Plex transcoding, or heavy surveillance workloads. If you find yourself wanting more, the DS124 is a good stepping stone. Learn DSM on the cheap, then upgrade to a DS225+ when your needs grow and repurpose the DS124 as an offsite backup unit.

*[Synology DiskStation DS124 on Amazon AU](https://www.amazon.com.au/dp/B0CBZ11HVD?tag=ntkit-22)*

- **CPU:** Realtek RTD1619B, 4-core, 1.7GHz
- **RAM:** 1GB DDR4 (not expandable)
- **Drive Bays:** 1x 3.5"/2.5" SATA
- **M.2 Slots:** Not included
- **Network:** 1x 1GbE RJ45
- **USB:** 2x USB 3.2 Gen 1
- **Hardware Transcode:** No
- **Power Consumption:** 10.69 W (Access, per Synology)
- **Warranty:** 2 years
- **AU market price:** about $255
- **Cheapest AU listing:** $239 (Computer Alliance, MSY, UMart)
- **Operating system:** DSM (DiskStation Manager)

**Pros**
- Cheapest way into the Synology DSM ecosystem
- Full DSM feature set including Synology Photos, Drive, and Hyper Backup
- Very low power consumption. Synology rates it at 10.69 W in Access mode
- Compact single-bay form factor
- Good as a backup target or offsite backup unit

**Cons**
- Single bay. No RAID redundancy, no data protection from drive failure
- 1GB RAM is very limited. Not suitable for heavy multitasking
- No hardware transcoding. No Plex, no video processing
- Cannot run Docker or virtual machines
- Only 1GbE networking
- 2-year warranty instead of 3 years (value series)

## UGREEN DXP2800 GT. The Newcomer to Watch

The [UGREEN NASync DXP2800 GT](https://ugreen.pxf.io/VOK1Ra) represents something genuinely new in the Australian NAS market. A well-funded hardware brand entering a space that has been dominated by Synology, QNAP, and Asustor for over a decade. UGREEN has built the DXP2800 GT around an AMD Ryzen Embedded R2514 processor with 8GB of DDR4 RAM, one 10GbE LAN port, and HDMI output. On paper, that is significantly more hardware than the Synology DS225+, which has a market price of about $599 against about $680 for the DXP2800 GT.

The hardware is genuinely impressive for a 2-bay NAS. The AMD Ryzen Embedded R2514 has four cores and the DXP2800 GT adds a 10GbE port, and its 8GB of DDR4 RAM may suit Docker containers or photo indexing, although memory sufficiency varies with workload and the number of concurrent services. The HDMI output adds direct-play capability that Synology does not offer. For buyers who prioritise raw hardware specifications, the DXP2800 GT offers strong hardware specifications, but its value depends on current Australian pricing and availability.

The concerns are real, though. UGREEN's NAS operating system (UGOS) is new and still maturing. It lacks the depth of DSM's app ecosystem, the years of community-built packages, and the battle-tested reliability of software that has been running on millions of devices worldwide. UGREEN sells direct through its own official store, UGREEN AU ([UGREEN AU](https://ugreen.pxf.io/0G54XP)), with warranty claims going straight to UGREEN AU and a 2-year warranty, 30-day returns, and 30-day price match included. The bigger factor to weigh against an established brand is software maturity, not warranty support. For a detailed look at UGREEN's NAS range and where it fits, see our [UGREEN NAS Australia guide](/blog/ugreen-nas-australia/).

> **Warning:** **Availability note:** This section covers the DXP2800 GT. The original UGREEN DXP2800 (Intel N100) is no longer listed by UGREEN AU or any tracked Australian retailer; UGREEN AU sells the DXP2800 GT in its place. UGREEN sells direct through its own official store, UGREEN AU, with warranty claims going straight to UGREEN AU and a 2-year warranty, 30-day returns, and 30-day price match included.

- **Hardware Transcode:** Possible via AMD GPU, per UGREEN; not tested by us
- **Operating System:** UGOS (UGREEN OS)
- **Warranty:** 2 years
- **AU Price (approx.):** about $719

**Pros**
- Strong hardware specs for a 2-bay NAS
- 8GB DDR4 RAM. Significantly more than competitors
- AMD Ryzen Embedded R2514 with 4 cores and a 10GbE port
- 10GbE and HDMI output
- Two M.2 SSD slots

**Cons**
- UGOS software is new and still maturing. Not in the same league as DSM or QTS yet
- Fewer Australian retailers stock it than Synology or QNAP models
- Limited app ecosystem compared to Synology and QNAP
- Smaller user community. Fewer guides, forums, and troubleshooting resources
- Long-term software support and update commitment is unproven
- Availability in Australia is inconsistent through traditional retail channels

## Buying a 2-Bay NAS in Australia: What You Need to Know

### Budget Beyond the NAS

Every NAS in this guide is sold diskless. You supply your own hard drives. Budget for the drives up front: a pair of NAS drives often costs as much as the NAS itself. NAS-grade HDDs like the Seagate IronWolf or WD Red Plus are designed for 24/7 operation and the vibration profile of a multi-drive enclosure. NAS-rated drives are designed and tested for 24/7 multi-drive operation and vibration; desktop-drive reliability and suitability vary by model and workload. Our [best NAS hard drive guide](/blog/best-nas-hard-drive-australia/) covers the options and current AU pricing in detail.

Factor in hard drive costs when budgeting for a 2-bay NAS system in 2026. The QNAP TS-233 has a market price of about $402. The Synology DS225+ has a market price of about $599. Add the price of your chosen enclosure to the current price of two NAS drives to estimate the total, which varies substantially with the enclosure and drive capacity; the [NAS Sizing Wizard](/tools/nas-sizing-wizard/) helps you choose drive capacity and shows current drive prices. At the entry level, that is comparable to a few years of cloud storage subscriptions. And you keep the data on your own hardware, on your own network.

### Where to Buy

Australian NAS prices can differ noticeably between retailers on the same model, so compare before buying. Beyond price, the meaningful difference between retailers is what happens when something goes wrong. For a product that stores your data, buying from a specialist retailer who can guide you through warranty claims and offer genuine pre-sales advice is worth a small premium over the cheapest price online.

Scorptec, PLE, and DeviceDeal list the widest NAS range in Australia. When buying through Amazon AU, pre-sales and after-sales support and the remedy offered for a faulty NAS can vary by seller, stock availability, and the circumstances of the fault, subject to Australian Consumer Law. For first-time NAS buyers, buying from a specialist is strongly recommended. For a comprehensive comparison of Australian NAS retailers, see our [where to buy NAS in Australia guide](/blog/where-to-buy-nas-australia/).

### Warranty and Australian Consumer Law

> **Tip:** **ACL protection:** Australian Consumer Law protections apply when purchasing from Australian retailers. For an ACL consumer-guarantee remedy, the retailer that sold the product must assist and cannot send you away to the manufacturer; a separate manufacturer's warranty follows the warranty provider's published claim process. Synology, QNAP, and Asustor do not have service centres in Australia. Warranty handling routes and turnaround times vary by retailer, distributor, vendor, and the circumstances of the claim. Before buying, ask your retailer: "If this fails, what is your warranty process? Is an advanced replacement available?" The answer tells you more about the value of buying from that retailer than the price on the website.

Warranty periods vary: Synology Plus-series models (DS225+) come with 3 years extendable to 5. Synology Value series (DS124) and QNAP entry models (TS-233) typically offer 2-3 years. Asustor provides 3 years across most of its range. UGREEN's official Australian NAS store advertises a two-year product warranty, 30-day returns and an Australian return process for purchases made through that store. For any NAS purchase, consider a [proper RAID configuration](/blog/nas-raid-explained/) and offsite backup strategy. A NAS is not a backup on its own, and hardware failure is a matter of when, not if.

## Which 2-Bay NAS Should You Buy?

The decision tree is straightforward once you know your priorities:

**Best overall for most buyers:** Synology DS225+ (about $599). The combination of DSM software and 2.5GbE networking makes it the most capable and user-friendly 2-bay NAS available. If you can only buy one NAS and want it to just work, this is the one.

**Best for budget file storage:** QNAP TS-233 (about $402). If you need networked storage and backup without Plex transcoding or advanced features, the TS-233 costs well under the Synology DS225+ (about $599) while delivering reliable file serving. Accept the 1GbE limitation and QTS learning curve in exchange for genuine savings.

**Best for Plex and media:** Asustor AS5402T (about $545). The HDMI output, powerful N5105 CPU, 4GB expandable RAM, and dual 2.5GbE make this the clear media-focused pick. It handles everything Plex can throw at it and connects directly to your TV. Accept that ADM software is less polished than DSM.

**Best ultra-budget entry:** Synology DS124 (about $255). The cheapest way into the Synology ecosystem. Use it as a backup target, cloud replacement, or stepping stone. But understand the single-bay limitation means no RAID protection.

**Worth watching:** UGREEN DXP2800 GT. Impressive hardware for a 2-bay NAS; the original DXP2800 it replaces is no longer listed in Australia. Suitable for technically confident buyers willing to accept the early-adopter trade-offs. Not recommended for first-time NAS users who value support and community resources.

Whichever model you choose, remember that the NAS enclosure is only part of the investment. Budget for quality [NAS-rated drives](/blog/best-nas-hard-drive-australia/), set up a proper backup strategy (a NAS alone is not a backup), and buy from an Australian retailer who can support you if something goes wrong. For a broader view of the Australian NAS market across all bay counts, see our comprehensive [best NAS Australia 2026 guide](/blog/best-nas-australia/).

**Q: Is a 2-bay NAS enough for home use?**

For most Australian households, yes. Two 8TB drives in RAID 1 provide 8TB of redundant storage, which comfortably handles photo libraries, documents, music, and a moderate video collection. If you are storing 4K Blu-ray rips or managing large video editing projects, you may need more capacity. But for typical home use including Synology Photos, Time Machine backups, and file sharing, a 2-bay NAS is more than sufficient. The main limitation is expandability: you cannot add more bays later without replacing the unit.

**Q: Should I get a 2-bay or 4-bay NAS?**

If you are confident that two bays will meet your storage needs for the next 3-5 years, a 2-bay NAS saves money on both the enclosure and drive costs. If there is any chance you will need more storage, a 4-bay NAS is the safer long-term choice. You can start with two drives and add more later. The Synology DS225+ has a market price of about $599. The Synology DS425+ has a market price of about $899. The 4-bay model costs noticeably more, but the extra is worth paying if it avoids buying a whole new NAS in two years.

**Q: Can I use a 2-bay NAS as a Plex server?**

It depends on the model. Intel models with hardware transcoding, such as the Asustor AS5402T, handle Plex well, including 4K to 1080p transcoding for remote streaming. The Synology DS225+ has an Intel CPU, but Plex hardware transcoding is not officially supported on it. ARM-based models like the QNAP TS-233 and Synology DS124 have no Plex hardware transcoding and Plex rates their software transcoding only up to 720p (some 1080p), so plan on direct play for larger files (the client device must support the original file format). If Plex is a priority, choose a model on Plex's supported NAS list with hardware transcoding. For detailed comparisons, see our [best NAS for Plex guide](/blog/best-nas-for-plex-australia/).

**Q: What hard drives should I use in a 2-bay NAS?**

Use NAS-rated drives designed for 24/7 operation: Seagate IronWolf, WD Red Plus, or WD Red Pro. Standard desktop drives are not designed for the vibration and always-on workload of a NAS and will fail sooner. For a 2-bay NAS, 4TB to 8TB drives hit the sweet spot between capacity and cost in Australia. NAS drive prices have risen from early 2025 levels, so check current prices before you budget. Our [NAS hard drive guide](/blog/best-nas-hard-drive-australia/) has detailed recommendations and current AU pricing.

**Q: Can I access my 2-bay NAS remotely over the internet?**

Yes, all major NAS brands offer remote access solutions. Synology's QuickConnect is the easiest. It creates a relay connection that bypasses CGNAT and does not require port forwarding. QNAP offers myQNAPcloud with similar functionality. Asustor uses EZ-Connect. Be aware that remote access speed is limited by your NBN upload speed, not your NAS. On a typical NBN 100 plan, expect 20-40Mbps upload, which is fine for documents and photos but slow for large video files. If your connection uses CGNAT (common on fixed wireless and some FTTN connections), relay services such as QuickConnect are a practical option without a VPN or third-party tunnel; depending on your ISP and network, you may instead be able to obtain a public IPv4 address or use supported IPv6 connectivity.

**Q: Is the Synology DS225+ worth the extra money over the QNAP TS-233?**

If your use case goes beyond basic file storage, yes. The DS225+ offers 2.5GbE networking (2.5x faster file transfers) and DSM's significantly more polished software. Plex hardware transcoding is not officially supported on the DS225+, so do not pay the premium for it. The DS225+'s premium over the TS-233 also buys you Synology's stronger security track record and a larger community for troubleshooting. If all you need is a networked file store for documents and backups with no media transcoding, the TS-233 does the job adequately and saves you money that could go toward better drives.

**Q: Should I buy the UGREEN DXP2800 GT or a Synology now?**

If you need a NAS now, buy the Synology DS225+. It runs proven software with a decade of refinement, has full Australian warranty support through established retailers and distributors, and an enormous community for help. The UGREEN DXP2800 GT offers more hardware, and UGREEN AU lists it, but UGOS is a new operating system that is still maturing. If you are technically confident, comfortable troubleshooting software issues, and willing to accept early-adopter trade-offs, the DXP2800 GT is worth considering. For everyone else, the established brands are the safer bet in 2026.

**Q: Do I need 2.5GbE networking on my NAS?**

Not immediately, but it is a worthwhile feature to have. If your current router and devices are all gigabit, a 2.5GbE NAS port will not make a difference today. But when you upgrade your router or add a 2.5GbE switch, you will get roughly 280MB/s file transfer speeds. A noticeable improvement for moving large files, photo libraries, or video projects. Given that a 2-bay NAS should last 3-5 years, buying one with 2.5GbE now avoids regret later as faster networking becomes standard in home equipment.

**Q: What RAID should I use in a 2-bay NAS?**

Common two-bay options include separate Basic volumes, JBOD, RAID 0 and RAID 1; Synology models also support SHR. For almost every user, [RAID 1 is the correct choice](/blog/nas-raid-explained/). RAID 1 mirrors your data across both drives. If one drive fails, the other contains a complete copy. You lose half your raw capacity (two 8TB drives give 8TB usable), but you gain protection against a single drive failure. RAID 0 stripes data across both drives for maximum capacity and speed but offers zero redundancy. One drive failure means total data loss. On a two-drive pool, SHR provides mirroring and one-drive fault tolerance equivalent to RAID 1, while retaining SHR's automated management behavior.
