Cloud Storage vs External Hard Drive: Which to Use?
Compare cloud storage and external hard drives for photos, documents and backups in the UK: cost, security, convenience, reliability and how to combine them.
Where should your photos, documents and backups live? The honest answer is usually "both", but the right balance depends on how much you store, how you work and how comfortable you are with subscriptions and with trusting a company with your files.
How they differ
Cloud storage keeps your files on remote servers, accessible from any device with an internet connection. You pay a subscription for space beyond a small free allowance.
An external hard drive (or SSD) is a physical device you own, plugged into your computer. You pay once and the files stay under your roof.
Comparing them honestly
| Factor | Cloud storage | External drive |
|---|---|---|
| Cost | Ongoing, typically a few pounds a month for larger plans | One-off, often £40 to £120 depending on size |
| Access | Anywhere, any device | Only where the drive is |
| Automatic | Usually, once set up | Needs plugging in and a schedule |
| Fire or theft protection | Yes, files are off-site | No, unless stored away from home |
| Speed for large files | Limited by internet | Fast |
| Privacy | You trust a provider | You control it |
| Failure risk | Provider or account problems | Drives fail, get lost or dropped |
| Sharing | Easy links and shared folders | Hand it over or copy |
When cloud storage is the better fit
- You want files available on phone, tablet and computer.
- You share photos and documents with family or colleagues.
- You do not want to remember to back up.
- You are worried about fire, theft or flooding at home.
- You have modest amounts of data or a decent internet upload speed.
When an external drive is the better fit
- You have large collections of photos or video that would be costly to store online.
- Your internet upload speed is slow.
- You prefer not to pay monthly.
- You want an offline copy that ransomware cannot easily reach if unplugged.
- Privacy is a priority.
Why using both is wise
Neither is perfect alone. A drive can fail or be stolen along with your laptop. A cloud account can be locked, hacked or closed. Combining them follows the 3-2-1 idea explained in how to back up your computer: keep multiple copies, on different kinds of storage, with at least one away from home.
A practical pairing:
- Cloud storage for current documents and phone photos, syncing automatically.
- An external drive for a full periodic copy and the large archive.
Security tips for either
- Protect the cloud account with a strong, unique password and two-factor authentication. See two-factor authentication explained.
- Encrypt the external drive if it holds sensitive files, and keep it somewhere safe.
- Beware of sync, not backup. Deleting a file in a synced folder deletes it everywhere, though recovery windows may exist.
- Check the terms, including where data is stored and what happens if you stop paying.
- Test restores occasionally.
Replacing or retiring storage
Drives wear out, and cloud plans change. When you replace or dispose of old drives, erase them properly. See disposing of old computers and phones safely. If a drive fails, data recovery costs gives context on what to expect.
For small businesses
Cloud storage with proper access controls makes it simple to share files and remove access when staff leave, while a separate backup protects against mistakes and ransomware. See small business IT basics.
Getting help
If you would like help choosing and setting up either, you can search Compito by postcode, compare ID-verified local providers and send a request describing what you want to store. You receive an offer to accept and pay online and can message the provider to agree the plan. See tech support services.
A worked example: sizing it up
Suppose a family has about 60GB of phone photos, 20GB of documents and 400GB of older family videos. The free allowance on most cloud services will not cover that, and a paid plan for 1TB is typically a few pounds a month, so a year or two of fees may approach the cost of a drive. The sensible split is often: the current photos and documents in the cloud, so everything is off-site and on every device, and the 400GB archive on a drive kept in a drawer, with a second copy on a different drive if the videos are irreplaceable.
Questions to ask yourself
- How much data do I have now, and how fast is it growing?
- Would I be upset, or in trouble, if this vanished tomorrow?
- Do I need to open these files away from home?
- Who else, such as a partner or an accountant, needs access?
- Would I remember to plug in a drive every week?
If the honest answer to the last question is "no", automatic cloud syncing is probably better for you than a drive that sits unused.
Common mistakes
- Treating one external drive as the whole plan. It can be dropped, stolen or fail, taking the only copy with it.
- Keeping the drive plugged in permanently next to the computer, where a power surge, fire or ransomware can reach both.
- Assuming cloud sync is a backup. If a file is corrupted or deleted locally, the damage may be mirrored.
- Ignoring the account recovery details. If you lose access to the email or phone behind the cloud account, you may lose the files.
- Never opening the backup. A backup you have not tested is a hope, not a plan.
Slow broadband and large first uploads
The first upload to the cloud can take days on a typical home upload speed, particularly with large photo and video libraries. Let it run overnight, avoid putting the computer to sleep, and consider starting with the most important folders. After the first upload, changes are small and quick.
Older and less confident users
For relatives who are not comfortable with technology, a drive that needs manual action may never get used, while a cloud service that quietly runs in the background gets the job done. Whichever you choose, write down where things are kept and who can help, and consider giving a trusted person the recovery details.
Frequently asked questions
Is cloud storage safe for private documents?
It can be, with a strong password and two-factor authentication. For extremely sensitive files, consider encrypting them before upload.
How long does an external drive last?
It varies with use and quality, but plan for a lifespan of a few years and replace before it fails.
Do I lose my files if I stop paying for cloud storage?
Typically you have a period to download them, but policies differ. Check the terms and keep a local copy.
