Choose cloud storage if access across several devices matters most; choose an external hard drive for a large local library, or a portable SSD if you frequently carry and copy large files. For photos and documents you cannot replace, keep separate local and offsite copies rather than relying on any one drive or account, and test that you can restore a file.
If photos, videos and documents keep accumulating, an external hard drive gives you a local place for a complete copy. Keep that copy separate from the computer when it is not being updated; the National Cyber Security Centre advises storing important backups in a separate safe location.
If you need current files on a computer, phone or tablet, cloud storage may fit your daily use. Check which folders and photos the service actually includes, as described in Microsoft Support's OneDrive guidance and Apple's iCloud information.
If you regularly move large photo or video libraries between devices, a portable SSD is worth considering. Check the connection and capacity as carefully as the advertised speed; carrying one drive does not create a second backup copy.
Choose it when: You want a large local copy and are willing to connect the drive for backups.
Accept that: A drive kept beside or attached to the computer remains exposed to the same local incident.
Choose it when: You often carry a library or copy large files between devices.
Accept that: Transfer claims depend on the particular SSD and host connection, and one portable drive is still one copy.
Choose it when: You need files available across devices and have dependable internet access.
Accept that: Capacity depends on the plan, while access depends on the account and its recovery options.
Choose it when: Losing irreplaceable photos or documents would be especially disruptive.
Accept that: You must maintain and check both copies. The National Cyber Security Centre advises keeping copies on separate devices, with one offsite.
| Concern | What to check | Who this matters to |
|---|---|---|
| Room for a growing library | Measure your files and allow for growth; include other backups or files that share a cloud allowance. | If my photo library keeps growing, I need the complete copy to fit without repeatedly changing storage arrangements. Around 29% of consumers put capacity and the choice of local storage over a continuing subscription first. |
| Access across devices | Check supported devices and which folders or photo libraries are included; consider internet access. | I want current files on my computer and phone without connecting a drive each time. For around 29% of consumers, cross-device access is the primary need. |
| Portable file transfers | Match the SSD connection and capacity to your devices and complete library; read speed claims under their stated conditions. | Moving large photo or video folders between devices is a regular task for me, and I need a copy I can carry. Around 21% of consumers place portable transfers first. |
| Recovery after a loss | Keep copies separate, check backup coverage and account recovery options, and test a file restore. | If a device or account becomes unavailable, I need another copy I can actually retrieve. Recoverability is the main concern for around 21% of consumers. |
A connected drive can be affected by an incident involving the computer. Cloud synchronisation also needs its folder selection and file-recovery settings checked; access to the account is part of being able to recover files.
Keep important copies in separate places, confirm what is included and restore a test file. For irreplaceable data, retain both a local and an offsite copy.
Videos, documents and device backups may need room too. Google One says its storage is shared across Google Drive, Gmail and Google Photos, so a photo library need not be the only use of that allowance.
Measure everything you intend to store, allow for growth and check which services draw on the same cloud allowance.
A transfer-rate claim depends on the model and connection. Even a fast SSD cannot hold a complete local backup if its capacity is too small for the library.
Check the computer connection, cable and stated speed conditions, then compare the drive capacity with the files you intend to copy.
Cloud files can be difficult to reach without working recovery details. Apple Support says its account recovery process can take several days or longer.
Keep recovery contacts current and secure, and retain a separate copy of irreplaceable files that does not depend on access to that account.

These portable SSDs and an external hard drive are options for keeping a local copy of a growing file library. Choose capacity against the size of your own files, check the connection to your devices, and keep a separate offsite copy if the files are irreplaceable.

Consider this for a portable local copy of photos and files. Check that 1 TB accommodates your library and that your device connection suits the drive's USB 3.2 Gen 2 interface. Keep another copy of irreplaceable files elsewhere.

This portable local-storage option may suit files moved between compatible devices. Its title specifies USB 3.2 Gen 2 and iPhone 15/16 compatibility; check your exact phone and case if you intend to use the magnetic attachment. Confirm that 1 TB fits the full library you plan to copy.

Consider this 2 TB portable SSD if you want a local copy with more room than a 1 TB option. Measure the library and check the drive's connector against your device before buying. Maintain another copy separately if the files cannot be replaced.

This 4 TB portable SSD is an option for a larger local library. Its title specifies USB Type-C and USB 3.2 Gen 2; check your computer's connection before relying on transfer-speed claims. Do not treat this single drive as an offsite backup.

This 5 TB portable hard drive is a local-copy option for a growing library on a Mac. Check the backup format before setting it up; if you also need Windows access, confirm the required driver arrangement. Confirm the applicable warranty terms before buying, and store a separate backup elsewhere.
Do not assume that cloud storage covers every photo, folder or file version. Check what is selected, what recovery features are available and whether you can restore a test file. For irreplaceable photos, keep a separate local copy as well; the National Cyber Security Centre recommends keeping important backup copies in a separate safe location.
Start with the size of your existing photos, videos and documents, then allow for growth and any device backups sharing the space. For a cloud plan, check the full account allowance rather than the photo library alone; Apple's iCloud information and Microsoft's Microsoft 365 information describe plans with different capacities.
Possibly, but check the backup software and file-system requirements before formatting the drive. Western Digital Support notes that macOS Time Machine uses an APFS-formatted external drive, while Windows File History can save copies to an external drive or network location. Verify the setup for both systems before putting important files on the drive.
Set up recovery options while you still have access to the account, and keep another copy of irreplaceable files. Google Account Help advises keeping recovery information current; Microsoft Support describes the need for an accessible contact email during account recovery, and Apple Support warns its recovery process may take several days or longer.
Check that recent files are included and restore a test file rather than assuming a completed copy is usable. Repeat the check as your library and devices change, and keep at least one important copy separate from the live device, in line with National Cyber Security Centre backup guidance.
