The Storage Question Every Small Business Eventually Asks

"Should we buy a NAS or just use cloud storage?" is one of the most-asked small-business IT questions. The answer is: it depends on what you’re actually trying to solve, and the honest answer for most small businesses in 2026 is "cloud storage plus a NAS," not either/or. This guide walks through when each wins on its own, when you need both, and the specific decision points.

What Each Solves

NAS (Network Attached Storage) is a dedicated storage appliance sitting on your office network. Files live on the NAS; users on the same network access them at LAN speed. Modern NAS boxes (Synology, QNAP, TerraMaster) also offer cloud-sync capabilities, remote access, and their own SaaS-style apps.

Cloud storage (OneDrive, Google Drive, Dropbox Business, Box) puts files on someone else’s infrastructure, accessed over the internet from anywhere. Backup and versioning are typically included. Access controls are managed through the platform’s admin console.

They solve overlapping but not identical problems. NAS is optimized for high-speed local file access and lots of storage at low per-TB cost. Cloud is optimized for anywhere-access, always-current, and no infrastructure to maintain.

Where Cloud Storage Wins on Its Own

Fully remote or hybrid teams. If everyone works from home some or all of the time, cloud storage is essential and NAS becomes marginal. Users don’t want to VPN in to reach a file server; cloud storage is native to their workflow.

Under 1 TB of active business data. Cloud storage tiers under 1 TB cost $10–$30/user/month for OneDrive/Google Workspace/Dropbox. NAS becomes worth the hardware investment above ~2–5 TB for cost-per-TB reasons.

Simple use cases. If your business runs on Word docs, spreadsheets, and PDFs — the SaaS-native world — cloud storage is more than sufficient. No specialized workflow.

Teams that need real-time collaboration. Microsoft 365 and Google Workspace’s real-time co-editing works only on files stored in their cloud. Files on a NAS don’t get real-time collaboration.

Where NAS Wins on Its Own

Large files, local team. Video editing, CAD, RAW photo processing, engineering data. Cloud storage upload/download speeds are the bottleneck; LAN-speed NAS access is 10-100x faster.

Above 10 TB of storage needed. Cloud storage becomes expensive above ~5 TB/user. NAS storage is roughly $30–$60/TB after hardware amortization vs $10–$50/TB/month for cloud at scale.

Regulated data requiring on-prem control. Some compliance regimes (defense contracting, healthcare, financial services) require or strongly favor on-prem storage for certain data classes. NAS gives you the physical control.

Bandwidth-constrained offices. If your office internet is slow, moving lots of data around via cloud is painful. NAS keeps the bulk data local.

Where You Need Both

Most growing small businesses eventually run both. NAS for bulk local storage (video archives, project files, backup targets); cloud for active collaboration files (documents, spreadsheets, presentations). The NAS becomes a backup destination for the cloud-stored files AND a local repository for the large-file workflows the cloud doesn’t handle well.

Best-of-both patterns:

• NAS as the primary backup destination for cloud-stored M365/Google Workspace data (using a third-party M365 backup vendor).
• NAS for large-file workflows; sync selected folders to cloud for external access.
• Cloud for day-to-day work; NAS for archive of completed projects.

Cost Comparison (Realistic Numbers)

Cloud storage at 15 users, 200 GB average per user (3 TB total active): Microsoft 365 Business Standard at $12.50/user/month = $2,250/year. OneDrive gives you 1 TB per user, plenty of headroom.

NAS at 15 users, 3 TB active storage: Entry Synology 2-bay ($500) + 2× 8TB drives ($400) + admin time = ~$1,200 initial, near-zero ongoing (electricity, occasional support). Amortized over 5 years = $240/year plus your time.

Cloud storage at 15 users, 200 GB average per user, above M365 tier: Dropbox Business Standard at $15/user/month = $2,700/year. Adds features beyond OneDrive but at added cost.

NAS is dramatically cheaper for raw storage at scale. Cloud is dramatically better for collaboration and mobility. That’s the honest tradeoff.

NAS Buying Considerations

For small business, Synology is the most-recommended brand for good reason — the admin interface, community support, and third-party app ecosystem are best-in-class. Entry models like the DS223j (2-bay) or DS423 (4-bay) are appropriate for offices under 15 users. Growing offices should look at the DS923+ or DS1522+.

QNAP is Synology’s main competitor, similar quality, sometimes better price, slightly more technical admin experience. TerraMaster is budget-friendly with acceptable quality if you’re comfortable with more DIY.

To browse current models: Synology NAS options and QNAP alternatives. For hard drives, buy NAS-rated drives (WD Red Plus or Seagate IronWolf) — regular desktop drives can fail early under NAS workloads.

Cloud Storage Buying Considerations

Microsoft 365 or Google Workspace bundle it in. If you already pay for either, the 1 TB/user OneDrive or Google Drive quota is usually all you need. Don’t add Dropbox on top unless you have a specific reason.

Dropbox Business is worth considering for teams heavily reliant on Dropbox’s collaboration model (Paper docs, external sharing UX) — often marketing agencies, creative shops, and consultancies.

Box is worth considering for regulated industries with heavier compliance requirements.

Common Mistakes

Using consumer Google Drive/Dropbox for business. Consumer accounts lack admin controls, audit logs, retention policies, and offboarding capabilities. Business tier is required.

Buying NAS without a backup strategy for it. The NAS itself needs backing up. RAID protects against drive failure, not against ransomware, deletion, or fire. Follow the 3-2-1-1-0 rule (see our backup guide).

Assuming cloud sync is backup. Cloud file sync mirrors deletions and corruptions in real time. If ransomware encrypts a file locally, the cloud has the encrypted version. Real backup requires versioning + separate third-party backup service.

Overprovisioning storage "just in case." Cloud storage is easy to scale up. NAS is easy to expand within the box (add drives) but painful to migrate to a bigger box. Buy for 18-month horizon, plan the growth path, don’t pay for storage you won’t use.

Key Takeaways

• NAS wins for: large files, local team, above 10 TB, regulated data, bandwidth-constrained office.
• Cloud wins for: remote/hybrid teams, under 1 TB per user, simple document workflows, real-time collaboration.
• Most growing businesses need both — cloud for active work, NAS for bulk local storage and backup.
• Cost: NAS dramatically cheaper for raw storage at scale; cloud better for collaboration and mobility.
• Synology is the go-to small-business NAS brand; QNAP is close competitor; use NAS-rated drives.
• Cloud storage bundled with Microsoft 365 or Google Workspace is often sufficient — don’t stack Dropbox unless you have specific reason.

FAQ

Is a NAS worth it if we already pay for Microsoft 365? Depends on your storage needs. If under 1 TB per user, M365’s included storage is usually enough. Above that, a NAS becomes worth the hardware investment.

Can a NAS replace cloud storage entirely? Only for teams that are 100% in-office and don’t need collaboration on the go. Most modern teams need at least some cloud storage even if the bulk is on NAS.

What’s the best NAS for a small business under 15 users? Synology DS223j or DS423+ for basic file sharing; DS923+ for growing offices with more demanding workflows.
