Synology Drive vs Dropbox — NAS File Sync Comparison

Synology Drive running on a local NAS delivers faster file sync, unlimited storage with no monthly fees, and complete data sovereignty, while Dropbox charges Australian users $17.99/month or more for convenience that comes at the cost of ongoing subscription fees and third-party data hosting. Dropbox is polished, widely understood, and works out of the box. But for Australian households and small businesses with growing file libraries, the maths increasingly favours a NAS. A Synology DS225+ ($549 at Scorptec, $585 at Mwave) with Synology Drive Server installed gives you selective sync, file versioning, real-time collaboration, mobile apps, and desktop clients across Windows, macOS, and Linux. All running on hardware you own, on your local network, with no recurring costs. This guide compares the two platforms feature by feature, breaks down the real costs in Australian dollars, and helps you decide which setup fits your workflow.

Why This Comparison Matters in 2026

Dropbox has steadily increased its Australian pricing while reducing the generosity of its free tier. The free plan now offers just 2GB. Barely enough for a handful of project folders. Meanwhile, Synology has invested heavily in Synology Drive, turning it from a basic file station replacement into a genuine Dropbox competitor with desktop sync clients, a web portal, mobile apps, on-demand file streaming, and team collaboration features. The gap between cloud file sync and local NAS file sync has never been smaller. If you already own or are considering a Synology NAS for your Australian home or office, Synology Drive comes free with DSM. No licence fees, no per-user charges, no storage caps. The question is whether Dropbox’s polish and ecosystem are worth the ongoing cost, or whether Synology Drive on a NAS delivers enough to replace it entirely.

Feature-by-Feature Comparison

Synology Drive Server and Client. What You Get

Synology Drive is a free package available in DSM’s Package Center. It consists of two components: Synology Drive Server, which runs on the NAS and manages files, versioning, sharing, and user permissions; and Synology Drive Client, the desktop application that syncs files between your computer and the NAS. There is also a mobile app for iOS and Android, and a web portal accessible from any browser.

The desktop client works much like Dropbox’s sync client. You designate folders on your computer to sync with the NAS, and changes propagate automatically. The on-demand sync feature lets you see all your NAS files in Finder or Explorer without downloading them. Files are fetched only when you open them, saving local disk space on laptops with smaller SSDs. This is functionally equivalent to Dropbox’s Smart Sync.

File versioning is configurable: you can retain up to 32 previous versions of each file with no time-based expiry. For comparison, Dropbox Plus keeps versions for 30 days, and you need the Professional or Business plan for 180-day version history. On a NAS with ample storage, keeping 32 versions indefinitely is a meaningful advantage for anyone working on documents, designs, or code that evolves over time.

Team folders allow multiple NAS users to share a common workspace with granular read/write permissions. Synology Office. Bundled free with DSM. Adds collaborative document editing, spreadsheets, and slides directly within the Drive web portal. It is not as polished as Google Docs or Microsoft 365, but for internal document collaboration it is serviceable and keeps everything on your own hardware. If you need a full step-by-step setup walkthrough, the process takes roughly 30 to 60 minutes from unboxing to syncing your first folder.

Dropbox Plans and AU Pricing

Dropbox’s Australian pricing as of early 2026 breaks down across four main tiers. The free plan is essentially a trial at 2GB. The Plus plan at $17.99/month (billed annually) provides 2TB of storage for a single user. The Professional plan at approximately $32/month adds 3TB, Smart Sync, watermarking, and 180-day version history. For teams, Dropbox Business starts at roughly $35/user/month with 5TB pooled storage, admin controls, and audit logs.

Those monthly fees compound quickly. A single Dropbox Plus user pays $215.88 per year. Over five years, that is $1,079.40. More than the cost of a Synology DS225+ ($549-$585) with a pair of 4TB NAS drives ($299 each at Scorptec for Synology HAT3300-4T). A small team of three on Dropbox Business at $35/user/month spends $1,260 per year, or $6,300 over five years. A Synology DS425+ ($819-$899) with four 8TB drives and Synology Drive Server serves the same team for a one-time cost under $3,000 with no per-user licensing.

Sync Speed. LAN vs Cloud

This is where the NAS advantage is most dramatic and least discussed. Synology Drive syncing to a NAS on your local gigabit Ethernet network transfers files at 100-115MB/s in practice. Wi-Fi 6 connections typically achieve 30-60MB/s depending on signal strength and congestion. Either way, syncing a 10GB folder of project files takes seconds to a few minutes.

Dropbox, by contrast, is limited by your internet upload speed. On a typical Australian NBN 100 connection, real-world upload speeds sit around 5-6MB/s (roughly 40-50Mbps). That same 10GB folder takes 25-35 minutes to sync to Dropbox. On NBN 50 plans, upload is even slower. For users working with large files. Video editors, photographers, CAD users, or anyone managing project archives. The difference between local NAS sync and cloud sync is the difference between waiting seconds and waiting the better part of an hour. Even Dropbox’s LAN Sync feature (which detects other Dropbox clients on the same network) only helps with syncing between computers, not with the initial upload to Dropbox’s servers.

Remote Access. Synology Drive Away from Home

Dropbox works identically whether you are at home, in a café, or overseas. Synology Drive requires slightly more setup for remote access. There are three main approaches:

QuickConnect is the easiest option. It is Synology’s relay service that routes your connection through Synology’s servers when a direct connection is not possible. It works behind most routers and even behind CGNAT (Carrier-Grade NAT), which affects some Australian NBN connections. Particularly those on fixed wireless or certain RSPs. QuickConnect is free, requires no port forwarding, and works with the Synology Drive desktop and mobile apps. The trade-off is speed: because traffic is relayed, transfer rates are slower than a direct connection, typically limited by your home upload speed.

DDNS with port forwarding gives you a direct connection to your NAS, which is faster but requires a public IP address (CGNAT blocks this) and opening ports on your router. This is a viable approach for users with a standard NBN connection and basic networking knowledge.

VPN (Tailscale, WireGuard, or Synology VPN Server) is the most secure option. It creates an encrypted tunnel to your home network, letting you access the NAS as if you were on your local LAN. Tailscale in particular works behind CGNAT and requires almost no configuration. For anyone serious about remote NAS access, a VPN is the recommended approach.

None of these options match Dropbox’s effortless anywhere-access. But for users who primarily work from home or the office and only occasionally need remote access, the setup investment is minimal and the ongoing cost savings are substantial.

Sharing and Collaboration

Dropbox has a clear edge in external sharing and third-party collaboration. Sending a Dropbox link to a client or colleague is universally understood. Dropbox integrates natively with Slack, Zoom, Trello, Microsoft 365, and dozens of other productivity tools. Dropbox Paper and the new Dropbox Dash further extend its collaboration features. For teams that rely on a broad SaaS ecosystem, Dropbox slots in seamlessly.

Synology Drive’s sharing is functional but more limited. You can generate password-protected share links with expiry dates, which is sufficient for sending files to external parties. Team folders with per-user permissions handle internal collaboration well. Synology Office provides basic real-time document editing. But there are no native integrations with Slack, Zoom, or other third-party tools. If your workflow depends on tight integration between your file sync platform and your broader software stack, Dropbox is genuinely better suited.

For internal teams that primarily share files amongst themselves and occasionally send links externally, Synology Drive covers the requirements. For teams that live in a SaaS-heavy workflow with frequent external collaboration, Dropbox’s integration ecosystem is a meaningful advantage that is difficult to replicate with a NAS.

Data Sovereignty and Privacy

This is increasingly a deciding factor for Australian businesses and privacy-conscious individuals. When you store files on Dropbox, your data resides on servers primarily located in the United States and is subject to US jurisdiction, including potential access under US law enforcement requests. Dropbox’s privacy policy permits them to access file metadata, and while file contents are encrypted at rest, Dropbox holds the encryption keys. Meaning they can decrypt your files if compelled to do so.

With Synology Drive on a NAS, your files never leave your premises unless you explicitly configure remote access. The data sits on drives you own, in a device you control, on your local network. There is no third party involved, no terms of service governing your data, and no foreign jurisdiction to worry about. For Australian businesses handling client data, medical records, legal documents, or financial information, keeping data on-premises on a NAS can simplify compliance with Australian Privacy Principles (APPs) and industry-specific data handling requirements.

This matters beyond compliance. If Dropbox changes its terms, raises prices, suffers a breach, or discontinues a feature, you are at the mercy of their decisions. With a NAS, your files are standard files on a standard file system. There is no vendor lock-in, no proprietary format, and no dependency on a third party’s continued existence. If Synology disappeared tomorrow, your files would still be accessible on the drives.

Total Cost of Ownership. NAS vs Dropbox Over Five Years

The cost comparison favours the NAS increasingly over time, because NAS hardware is a one-time purchase while Dropbox is a perpetual subscription. Here is a realistic five-year breakdown for two common scenarios.

Scenario 1: Single User / Home Office

For a single user with modest storage needs, Dropbox Plus is slightly cheaper over five years. But the NAS provides four times the usable storage (8TB raw, ~4TB in RAID 1 mirror), supports unlimited users at no extra cost, keeps all data local, and continues working beyond year five with no ongoing fees. If you need more than 2TB, or if a second household member also needs sync, the NAS wins on cost immediately.

Scenario 2: Small Team (3 Users)

For small teams, the NAS advantage is decisive. The NAS vs cloud storage calculation tips heavily in favour of local hardware once you have more than one user. The NAS serves all three users from a single device with no per-user fees, provides 16TB of usable storage in RAID 5, and saves over $3,000 compared to Dropbox Business over five years. Even factoring in a drive replacement during that period, the NAS still comes out well ahead.

Pros and Cons. Synology Drive

Pros and Cons. Dropbox

Who Synology Drive Suits Best

Synology Drive on a NAS suits users who work primarily from a single location (home office, small office) and want fast, reliable file sync without ongoing costs. It is particularly strong for:

Home offices and freelancers who generate large files. Photographers, videographers, designers, and developers. The LAN speed advantage alone justifies the NAS for anyone regularly syncing gigabytes of working files. A DS225+ at $549-$585 handles this effortlessly.

Small businesses (2-10 people) who primarily collaborate internally. Team folders with permissions, shared drives, and Synology Office cover the core collaboration needs without per-user subscription fees. A DS425+ ($819-$899) or DS925+ ($995-$1,029) provides the storage and performance for a growing team.

Privacy-conscious users and businesses handling sensitive data. Medical practices, legal firms, accountants, and anyone subject to Australian Privacy Principles benefits from keeping data on-premises rather than on US-hosted cloud servers.

Households that want a central file repository for the family. Multiple family members can sync documents, photos, and media through Synology Drive without each needing a separate Dropbox subscription.

Who Dropbox Suits Best

Dropbox suits users who prioritise effortless access from anywhere and rely heavily on third-party SaaS integrations. It is the stronger choice for:

Distributed teams and remote workers who need identical access from multiple locations, cities, or countries. If your team is not co-located and every member needs seamless cloud access without VPN configuration, Dropbox delivers this out of the box.

SaaS-heavy workflows that depend on integrations with Slack, Zoom, Trello, Asana, Microsoft 365, or Google Workspace. Synology Drive cannot replicate this integration depth. If your productivity stack revolves around these tools, Dropbox’s native connectors save time daily.

Users who want zero maintenance. Dropbox handles all infrastructure, redundancy, and updates. There are no drives to replace, no firmware to update, and no hardware to manage. For people who do not want to think about storage infrastructure at all, this convenience has real value.

Frequent travellers who need reliable file access from hotel Wi-Fi, airport lounges, and mobile connections. While Synology Drive’s QuickConnect works remotely, it cannot match the consistency of a purpose-built cloud platform with global CDN infrastructure.

Can You Use Both Together?

Yes, and many users do. A practical hybrid approach uses Dropbox for external sharing and collaboration with clients and contractors, while Synology Drive handles internal file sync and long-term storage. Synology’s Cloud Sync package (separate from Synology Drive) can connect your NAS to Dropbox, Google Drive, OneDrive, and other cloud services, automatically syncing designated folders between the NAS and the cloud. This gives you a local copy of everything on Dropbox, effectively using the NAS as a backup of your cloud storage. Or vice versa.

This hybrid approach lets you keep a small Dropbox plan for external-facing collaboration while using Synology Drive for everything internal. You get the best of both platforms without paying for a large Dropbox storage tier.

Buying a NAS in Australia. What to Know

If the NAS route makes sense for your situation, here are the key considerations for Australian buyers. Synology’s smaller product catalogue means most models are held in stock by major Australian retailers. Unlike some competitors where you may need to wait for stock to arrive from distributors. Both BlueChip and MMT distribute Synology in Australia with strong stock levels and dedicated product managers, which translates to reliable availability at retail.

For file sync workloads, the DS225+ ($549 at Scorptec, $585 at Mwave, $599 at PLE) is the sweet spot for home offices and single users. The DS425+ ($819 at Scorptec, $899 at Mwave, $999 at PLE) suits small teams needing more storage capacity and RAID 5 redundancy. Both models support Synology Drive Server with full functionality. Most Australian NAS retailers operate on 3-5% margins, so pricing is fairly uniform across stores. The real difference between retailers is what happens when something goes wrong. Buy from a specialist like Scorptec or PLE where you can get genuine pre-sales guidance.

Synology Drive's remote sync depends on your NBN connection. Our NBN Remote Access Reality Checker checks whether your ISP and plan support direct access or whether you'll need a relay.

Can Synology Drive fully replace Dropbox?

For internal file sync, versioning, selective sync, and mobile access. Yes, Synology Drive covers all the core features. Where it falls short is third-party integrations (Slack, Zoom, Microsoft 365) and effortless remote access from anywhere. If your workflow depends heavily on SaaS integrations or you need seamless access from multiple cities without VPN setup, Dropbox is still the more practical option. For home offices and small teams working primarily from one location, Synology Drive is a complete Dropbox replacement.

Does Synology Drive work over the internet when away from home?

Yes. QuickConnect provides remote access without port forwarding and works behind most routers, including those with CGNAT. Alternatively, you can configure DDNS with port forwarding (requires a public IP) or use a VPN like Tailscale or WireGuard for a secure, direct connection. Remote sync speeds are limited by your home NBN upload speed. Typically 5-6MB/s on an NBN 100 plan. Which is comparable to Dropbox’s speeds in the same scenario. For more detail, see our NAS remote access guide.

How much does a Synology NAS cost in Australia for file sync?

A capable file sync setup starts with the Synology DS225+ at $549-$599 depending on the retailer. Add two 4TB Synology Plus drives at $299 each ($598 total) for a RAID 1 mirror with 4TB usable storage. Total: approximately $1,150. For a small team, the DS425+ at $819-$999 with four 8TB drives ($499 each at Scorptec for HAT3320-8T) totals around $2,815 with 24TB usable in RAID 5. These are one-time costs with no ongoing subscription fees.

Is Synology Drive as fast as Dropbox for syncing files?

On your local network, Synology Drive is dramatically faster. Gigabit Ethernet delivers 100-115MB/s, while Dropbox is limited by your internet upload speed (typically 5-6MB/s on Australian NBN 100). That means a 1GB file syncs to a local NAS in about 9 seconds but takes nearly 3 minutes to upload to Dropbox. Over the internet (remote access), both are limited by your home upload speed, making them roughly equivalent for remote use.

What happens to my files if the Synology NAS fails?

If the NAS hardware fails, your files are still on the hard drives (assuming RAID is intact). A replacement NAS can typically reattach the existing drives and recover data. However, if multiple drives fail simultaneously or the NAS and drives are damaged (fire, theft, power surge), data could be lost. This is why a NAS should never be your only copy. Use Synology’s Hyper Backup to maintain an offsite backup. To a USB drive, a second NAS, or even a small cloud backup for critical files. Australian Consumer Law covers the hardware replacement but not your data.

Can I use Synology Drive and Dropbox at the same time?

Yes. Synology’s Cloud Sync package can connect your NAS to Dropbox, automatically syncing designated folders between the two. This lets you maintain a local NAS copy of your Dropbox files (or sync specific NAS folders to Dropbox for external sharing). Many users keep a basic Dropbox plan for external collaboration while using Synology Drive for day-to-day internal sync. Getting the best of both platforms without paying for a large Dropbox storage tier.

Does Synology Drive support selective sync like Dropbox Smart Sync?

Yes. Synology Drive Client supports on-demand sync, which shows all your NAS files in Finder (macOS) or Explorer (Windows) without downloading them. Files are fetched only when you open them, saving local storage on laptops with smaller SSDs. This is functionally equivalent to Dropbox’s Smart Sync feature. You can also configure traditional selective sync to choose which folders sync locally and which stay on the NAS only.
