10TB of cloud storage over 5 years costs anywhere from under $1,000 to over $20,000 depending on the provider, and some mainstream consumer services offer 10TB or more, although availability and pricing vary substantially. The consumer cloud market is built around plans up to 2TB. Getting to 10TB requires either a business or object storage account, a family plan arrangement, or buying multiple subscriptions. Each approach has different pricing, different upload constraints, and very different performance on Australian NBN connections.
In short: Single consumer plans above 10TB exist in Australia, including Apple’s 12TB iCloud+ plan, but they are considerably more expensive than mainstream 1TB-2TB tiers. Backblaze Personal Backup covers unlimited data (including 10TB+) for about $145/year AUD equivalent. Object storage services like Wasabi or Backblaze B2 charge per-TB and are cost-effective for archival. Recalculate the upfront and five-year NAS totals using current drive quotes, the selected model's measured power consumption and the buyer's electricity tariff. For 10TB, NAS is cheaper than every cloud option that charges on a per-TB basis after roughly 2-3 years.
Why 10TB Is a Cloud Storage Problem
Most cloud storage comparisons focus on 1TB or 2TB, because that is where the mainstream consumer market sits. But storage needs grow. A household with a modern mirrorless camera, 4K video from smartphones, and accumulated backups from multiple computers can reach 5-10TB quickly. Small businesses with working files, project archives, and surveillance footage can hit 10TB in a single year.
At 10TB, the mainstream consumer cloud services either do not have a plan, require expensive workarounds, or price the storage at a level that makes a NAS look extremely attractive. This article covers the full landscape: what exists, what it costs in AUD over 5 years, and how it compares to a purpose-built NAS.
For context on how upload speed affects cloud storage at this scale, see the section on NBN realities below. Backing up 10TB on a typical Australian NBN connection takes weeks, not hours, and this fundamentally changes how cloud storage can practically be used at this capacity.
Consumer Cloud Storage: The 2TB Ceiling
Dropbox Plus caps individual storage at 2TB, while Apple offers iCloud+ tiers through 12TB and Google offers higher-capacity options for eligible Google One plans. To reach 10TB through these services, you would need either a business account or multiple accounts, neither of which is a clean solution. Microsoft OneDrive via Microsoft 365 caps personal storage at 1TB for the Personal plan and 1TB per user on the Family plan (6 users maximum, totalling 6TB shared). Apple provides a 12TB individual plan, and Google documents a 10TB option for eligible plans; Microsoft 365 Personal and Dropbox Plus remain below 10TB per user.
Consumer Cloud Storage: Plan Caps and Pricing (AUD, 2026)
| Google One | Apple iCloud+ | Microsoft OneDrive (M365) | Dropbox Plus | |
|---|---|---|---|---|
| Maximum plan size | Up to 10TB or more on eligible Google One plans | 12TB individual | 1TB individual (M365 Personal) | 2TB individual |
| Price at maximum tier | 2TB price: $14.99/month ($179.88/yr); higher-capacity pricing depends on plan eligibility | $14.99/month ($179.88/yr) for 2TB; $89.99/month for the 12TB maximum tier | $159/year (M365 Personal) | ~$175/year (approx AUD) |
| 5-year cost at maximum tier | ~$1,019 | ~$1,079 | ~$595 | ~$875 |
| Path to 10TB? | No single-user plan | No single-user plan | No single-user plan | No single-user plan |
| Best for | General files, Google ecosystem | Apple device sync and photos | Microsoft Office users, 1TB included | File sync, collaboration |
The 2TB wall: If you need more than 2TB, Microsoft’s personal plans remain insufficient, while Apple and eligible Google One plans offer larger but substantially more expensive consumer tiers. You need to look at business plans, dedicated backup services, or object storage. Each category has very different pricing and use-case requirements.
Dedicated Backup Services: Unlimited or Near-Unlimited
These services back up computers under different limits and conditions: Backblaze is unlimited per licensed computer, IDrive uses plan capacity limits, and Carbonite external-drive support depends on the selected tier. These services typically charge a flat annual fee rather than per-TB pricing, making them attractive for large data volumes.
Dedicated Backup Services: Cost for 10TB+ (AUD Approximate, 2026)
| Backblaze Personal Backup | IDrive Personal | Carbonite Safe | |
|---|---|---|---|
| Storage limit | Unlimited (1 computer) | 10TB (top personal plan) | Unlimited (1 computer) |
| Annual cost (AUD approx) | ~$145/year (USD $99 converted) | US$125.88 for the promotional first year and US$179.88/year thereafter, converted to AUD at the applicable exchange rate | ~$200-300/year depending on plan |
| 5-year cost | ~$725 | US$845.40 over five years before currency conversion, assuming the current first-year promotion and four renewals at the current standard price | ~$1,000-$1,500 |
| Key limitation | 1 computer only, restore speed slow on NBN | 10TB cap, initial backup of 10TB takes weeks on NBN | File sync and backup, slower restore at 10TB scale |
| AU data centre? | No (US servers) | No (US/EU servers) | No (US servers) |
Backblaze Personal Backup is the most cost-effective unlimited backup service available to Australians, but there are significant practical limitations at 10TB scale. The initial backup of 10TB from Australia to the selected overseas Backblaze data region can take weeks or months, depending on sustained upload speed. Restoration of 10TB would similarly be extremely slow. Backblaze offers Restore by Mail using USB drives of up to 8TB each, so a 10TB restore requires multiple orders; drive fees may be refundable under its return terms, while shipping and import costs can still apply. Note: Backblaze ended its affiliate program in March 2026, but the service itself continues.
IDrive has a strong feature set and competitive pricing, but the 10TB cap requires the highest personal plan tier. It is a solid option for most households that fall under that threshold.
Object Storage: Wasabi, Backblaze B2, Amazon S3, Google Cloud
Object storage services are designed for programmatic access, archival, and developer use cases. They charge per-GB stored per month, plus fees for data transfer. For 10TB of archival data that you write once and rarely access, some of these services are remarkably cheap. For data you access regularly or download frequently, egress fees can make them expensive very quickly.
Object Storage: 10TB Monthly and 5-Year Cost (AUD Approximate, 2026)
| Backblaze B2 | Wasabi | Amazon S3 Standard | Google Cloud Storage | Cloudflare R2 | |
|---|---|---|---|---|---|
| Storage cost (per TB/month) | ~$8 USD (~$12 AUD) | ~$7 USD (~$11 AUD) | ~$23 USD (~$35 AUD) | ~$20 USD (~$30 AUD) | ~$15 USD (~$23 AUD) |
| Monthly cost for 10TB | ~$120 AUD | ~$110 AUD | ~$350 AUD | ~$300 AUD | ~$230 AUD |
| Annual cost for 10TB | ~$1,440 AUD | ~$1,320 AUD | ~$4,200 AUD | ~$3,600 AUD | ~$2,760 AUD |
| 5-year cost for 10TB | ~$7,200 AUD | ~$6,600 AUD | ~$21,000 AUD | ~$18,000 AUD | ~$13,800 AUD |
| Egress fees | Free egress up to 3x average monthly storage, then US$0.01/GB | No itemised egress fee, subject to Wasabi's free-egress policy, minimum-capacity billing and minimum-storage-duration rules | approximately US$114/TB from the Sydney region before applicable free allowances | Varies by source region, destination, volume and network tier; calculate using current Google Cloud Storage pricing | Free (another key differentiator) |
| AU data region available? | No | Yes (Sydney region) | Yes (Sydney region) | Yes (Sydney region) | No AU region yet |
Amazon S3 and Google Cloud Storage egress fees: The storage cost for S3 and Google Cloud looks manageable until you need to retrieve your data. Downloading 10TB from Amazon S3's Sydney region can cost roughly US$1,129 in internet egress after a 100GB free allowance, before request charges and currency conversion. These services are designed for applications that access data in small, targeted operations, not for bulk restores of large datasets. If you are choosing object storage as a backup destination, factor the restoration cost into the total before committing.
Wasabi and Cloudflare R2 have disrupted this market by eliminating egress fees. Wasabi charges a flat per-TB storage rate with no transfer costs, making it predictable for backup use cases. Wasabi does not have an affiliate program available to publishers, but the service is genuinely competitive for this use case. Cloudflare R2 offers similar pricing and a best-effort Oceania location hint, but it does not provide an Australia-specific data-location guarantee.
For context, Using the article's stated five-year NAS totals, Wasabi at roughly $1,320/year is about 3.3 to 4 times the NAS's annualised five-year cost. It is a viable option for specific scenarios, such as storing data that needs to be accessible from multiple locations or integrating with applications that natively support S3-compatible storage. It is not cost-competitive with a NAS for straightforward home or small business backup at 10TB.
Business Cloud Storage Plans at 10TB
Google Workspace, Microsoft 365 Business, and Dropbox Business offer pooled storage for teams, but they are designed for organisations with multiple users, not households that need more than 2TB. Google Workspace Business Standard provides 2TB per user with 5 users minimum, potentially reaching 10TB across the team. Microsoft 365 Business plans offer 1TB per user. These plans carry per-user monthly fees that add up quickly for a household that just wants more storage.
Business Cloud Plans: Reaching 10TB (AUD Approximate, 2026)
| Google Workspace Business Standard | Microsoft 365 Business Basic | Dropbox Business Plus | |
|---|---|---|---|
| Storage | 2TB per user (pooled) | 1TB per user | 15TB pooled for the three-licence minimum, with 5TB added per actively used licence |
| Minimum users to reach 10TB | 5 users (10TB pooled) | 10 users (10TB pooled) | 3 users (15TB pooled) |
| Monthly cost to reach 10TB | ~5 x $19 = ~$95/month AUD | ~10 x $10.50 = ~$105/month AUD excluding GST on an annual commitment | ~2 x $30 = ~$60/month AUD (approx) |
| Annual cost to reach 10TB | ~$1,140/year | ~$1,128/year | ~$720/year (approx) |
| 5-year cost | ~$5,700 | ~$5,640 | ~$3,600 |
| Key trade-off | Paying for 5 user licences you may not fully use | Paying for 10 user licences for personal storage | Business pricing for what may be personal use |
Using business cloud plans to reach 10TB as an individual is technically possible but economically poor. You are paying for user licences you do not need. The 5-year cost of $3,600-$5,700 for business cloud plans at 10TB is substantially higher than the NAS alternative discussed below.
The NAS at 10TB: What It Actually Costs
A purpose-built NAS with 10-12TB of usable storage is a realistic and well-understood solution. The hardware exists, it is available from Australian retailers, and it is a one-time purchase rather than a subscription. The main cost components are the NAS unit, the hard drives, and electricity.
NAS Build Options for 10-12TB Usable Storage (AUD, 2026)
| 4-bay entry: 12TB usable (RAID 5) | 4-bay mid: 18TB decimal RAID-5 capacity before filesystem and system overhead | 5-bay mid: 24TB decimal RAID-5 capacity before filesystem and system overhead | |
|---|---|---|---|
| NAS unit | Synology DS423 from $635 (Scorptec, Mwave) | Synology DS425+ from $848 (Mwave, Scorptec, PLE) | Synology DS1525+ from $1,600 (Mwave, Scorptec) |
| Drives | 4x 4TB NAS HDD ~$200 each = ~$800 | 4x 6TB NAS HDDs priced from current Australian retailer quotes | 5x 6TB NAS HDD ~$240 each = ~$1,200 |
| Upfront total | ~$1,435 | ~$1,808 | ~$2,800 |
| Usable storage (RAID 5) | ~12TB (3x 4TB) | ~16TB (3x 6TB) | ~24TB (4x 6TB) |
| Annual electricity | Calculate from the system's measured average draw and tariff | Calculate from the system's measured average draw and tariff | Calculate from the system's measured average draw and tariff |
| 5-year total cost | ~$1,670 | ~$2,043 | ~$3,075 |
The Synology DS423 and DS425+ are both widely available at Australian retailers including Mwave, Scorptec, and PLE. The DS425+ is the recommended choice for most buyers: it runs a faster processor, supports more simultaneous applications, and delivers better performance for workloads beyond pure file storage. The DS423 suits users who need basic storage and backup only. The DS1525+ is a 5-bay model that provides more headroom for expansion and supports higher total storage capacity, but it carries a significantly higher upfront cost.
QNAP and Asustor offer comparable 4-bay units in a similar price range. The QNAP TS-433 (from~$697 at Mwave Australia, Scorptec, PLE) and the current Asustor DRIVESTOR 4 Pro Gen2 AS3304T v2 are both capable alternatives. The decision between brands comes down to software preference: Synology DSM is widely considered the most user-friendly, while QNAP's QTS offers more advanced features for technical users.
The Full Cost Comparison: Every Option at 10TB Over 5 Years
10TB Storage: All Options, 5-Year Total Cost (AUD Approximate)
| Consumer cloud (max 2TB each) | Backblaze Unlimited Backup | Wasabi Object Storage | B2 Object Storage | Business cloud (10TB) | NAS (12TB usable) | |
|---|---|---|---|---|---|---|
| 5x combined 2TB plans | $5,095 (5x Google One 2TB) | N/A | N/A | N/A | N/A | N/A |
| 5-year total | $5,095 (combined multi-account) | ~$725 (1 computer only) | ~$6,600 | ~$7,200 | Recalculate using the current three-licence Dropbox minimum and current Microsoft and Google per-user prices. | ~$1,663-$1,980 |
| Storage limit | 10TB (5x 2TB accounts) | Unlimited but 1 computer | 10TB | 10TB | 10TB pooled | 12-16TB usable |
| Access speed (AU) | Limited by NBN upload/download | Restore from selected overseas region | Fast (Sydney region available) | Overseas region only | Limited by NBN | LAN-speed (gigabit local) |
| Data sovereignty | US/EU servers | US servers | Sydney region available | US servers | US/EU servers | On-premise in AU |
The numbers make the case plainly. For 10TB of storage over 5 years, a NAS is the cheapest option by a significant margin among services that actually provide 10TB. The only cloud service that comes close in cost is Backblaze Personal Backup, but it backs up only one computer, stores data on US servers, and restores over your NBN download connection, subject to Backblaze and end-to-end throughput limits. Recalculate the NAS five-year total using current hardware prices, model-specific power consumption, the buyer's tariff and any expected drive-replacement allowance.
NBN Upload Speeds: Why 10TB and Cloud Storage Are a Bad Match for Australians
The mathematics of uploading and restoring 10TB on Australian NBN connections are not favourable. At a sustained 20Mbps upload rate, 10TB takes approximately 46 days at theoretical maximum speed; current nbn upload rates vary by access technology and retail plan. Real-world speeds during peak hours are often lower.
| Sustained upload rate: 10Mbps | 10TB initial upload: approximately 92 days |
|---|---|
| Sustained upload rate: 20Mbps | 10TB initial upload: approximately 46 days |
| Sustained upload rate: 25Mbps | 10TB initial upload: approximately 37 days |
| Sustained upload rate: 50Mbps | 10TB initial upload: approximately 18.5 days |
| Local NAS via GbE (gigabit Ethernet) | 10TB data transfer: roughly a day at sustained near-gigabit throughput, and longer with protocol or storage overhead |
| Key takeaway | Initial 10TB cloud backup takes weeks to months on any standard NBN plan. Full restoration can also take days, but its duration depends on download speed and provider throughput and is not generally equal to the upload time. Local NAS transfers the same data in under a day. |
This is not a reason to avoid cloud storage entirely, but it is a critical constraint for Australians considering cloud-first strategies at 10TB scale. Cloud storage is practical for ongoing incremental backups of new files, but the initial bulk upload and any full restoration are major undertakings. Some providers offer physical-media services; Backblaze Restore by Mail addresses restoration, while initial-backup seeding availability must be checked separately with each provider. Use the file transfer speed estimator to calculate realistic upload and download times for your connection and data volume.
CGNAT is a related issue for NAS users. Some Australian NBN providers place residential customers behind Carrier-Grade NAT, which blocks inbound connections to your home network. If you want to access your NAS remotely without going through a cloud relay, check whether your ISP uses CGNAT. Public-IP options vary by ISP: some allow a free CGNAT opt-out, while others charge for a public or static address or impose eligibility conditions.
Australian Buyers: Storage Market Context for 2026
NAS-grade hard drive prices have risen significantly in Australia through 2025-2026. Drives that were available for under $160 for 4TB models in early 2025 are now consistently above $200. This has pushed NAS build costs higher than older buying guides suggest. Prices should be refreshed against dated Australian retailer and provider quotes before publication.
All NAS hardware purchased from Australian retailers is covered by Australian Consumer Law. For an Australian Consumer Law remedy, the seller is responsible and cannot simply direct you to the manufacturer; consumers may also have rights against the manufacturer in some circumstances. Warranty handling and turnaround vary by retailer, distributor, vendor, fault and parts availability; confirm the retailer's process before purchase. For a device storing 10TB of important data, the choice of retailer matters as much as the choice of hardware. Specialist retailers like Scorptec and PLE offer more reliable pre-sales and after-sales support than purchasing from Amazon AU.
UGREEN NAS units are available in Australia direct through UGREEN's own official UGREEN AU store rather than through a third-party distributor. Warranty claims go to UGREEN AU; warranty length varies by model, with two years for DH, DX and most DXP units and three years for specified DXP6800 and DXP8800 models, alongside the stated return and price-protection terms.

Common Mistakes When Evaluating 10TB Cloud Storage
Mistake 1: Looking only at storage price, ignoring egress fees. Amazon S3 and Google Cloud Storage are competitively priced for storage, but retrieving 10TB of data costs hundreds of dollars in egress fees alone. Always calculate the restoration cost as part of the total cost of any object storage service.
Mistake 2: Treating Backblaze Personal Backup as a 10TB cloud storage solution. Backblaze Personal Backup is a backup service for one computer. It does not function as general-purpose storage, has mobile apps for browsing and downloading backed-up files, but is not a general-purpose sync drive, and restoring 10TB from US servers to an Australian address on NBN is a weeks-long process. It is excellent for its intended purpose, but that purpose is narrower than the name implies.
Mistake 3: Calculating cloud costs based on current pricing without considering future increases. Google One and Microsoft 365 have raised Australian prices in recent years; do not assume any provider's current price will remain fixed. Object storage providers have also adjusted pricing. A 5-year cloud cost calculation is conservative: actual costs over 5 years are likely higher. NAS hardware is a fixed upfront cost that does not increase.

Is there a cloud storage service that provides 10TB for a reasonable monthly fee?
Not at the consumer price point. The closest options are Backblaze Personal Backup (unlimited backup for one computer at roughly $145/year AUD equivalent) and Wasabi object storage (approximately $110/month AUD for 10TB). Neither is a general-purpose cloud drive in the way Google One or iCloud is. Apple offers a direct 12TB consumer iCloud+ plan in Australia, but its price is substantially above mainstream 1TB-2TB plans. A NAS is the most practical and cost-effective solution at this capacity.
How long does it take to upload 10TB to cloud storage from Australia?
On a standard NBN 100 plan with 20Mbps upload, uploading 10TB takes approximately 46 days at theoretical maximum speed. Actual time will exceed the theoretical minimum when bandwidth is shared, throttled or interrupted; estimate it using the connection's measured sustained upload rate. At 50Mbps upload the theoretical time is roughly 18.5 days; at the current eligible Home Ultrafast upload rate of approximately 100Mbps it is roughly 9.3 days, subject to retail-plan and access-technology limits. This upload time constraint is one of the primary reasons a NAS is more practical than cloud-only storage for Australians with large data volumes. The same data transferred over a local gigabit network to a NAS takes under 24 hours.
Which cloud storage provider is cheapest for 10TB in Australia?
For ongoing archival storage of 10TB, Wasabi is among the cheapest object storage options with an Australian region available (Sydney). At roughly $110/month AUD for 10TB with no egress fees, it costs approximately $1,320/year. Backblaze B2 is similarly priced but charges for downloads beyond a free daily threshold. Both are significantly more expensive per year than a NAS, which carries only electricity costs (roughly $47/year) after the upfront hardware purchase.
What NAS is best for 10-12TB of storage in Australia?
The Synology DS425+ (from $848 at Mwave, Scorptec, and PLE) paired with 4x 6TB NAS-grade hard drives provides approximately 16TB of usable storage in RAID 5, at a total build cost of roughly $1,745. It runs Synology's DSM software, which is the most user-friendly NAS operating system available, and supports automated cloud sync to Google Drive, OneDrive, and Synology C2 for offsite backup. For users who want more technical depth or specific connectivity, the QNAP TS-433 (from $639) or QNAP TS-464 (from $989) are solid alternatives. Buy from a specialist retailer like Scorptec or PLE for proper pre-sales and after-sales support.
Does cloud storage make sense at all for 10TB, or should I just buy a NAS?
For primary storage, a NAS is the practical choice at 10TB. Cloud storage at this scale is either unavailable in consumer form or expensive and slow on Australian NBN connections. However, cloud storage still serves an important role as offsite protection for your NAS data. The recommended approach for serious data at 10TB is a NAS for primary local storage, with automated cloud backup of your most critical data to a smaller, cheaper cloud plan. This hybrid approach provides speed, capacity, and offsite protection at a lower total cost than cloud-only storage at this volume.
Are there any Australian cloud storage providers with local data centres?
Several object storage providers have Sydney region data centres, including Wasabi, Amazon S3, and Google Cloud Storage. , and Microsoft has Azure data centres in Australia that host some Microsoft 365 data. Synology C2 does not offer a Sydney region; current C2 OneStorage choices are Frankfurt and Seattle, while eligible existing APAC customers may retain Taiwan. Having data stored locally in Australia reduces latency for uploads and downloads and addresses some data sovereignty concerns, but it does not change the fundamental bandwidth constraints of Australian NBN upload speeds for large initial backups.
