Choose an external hard drive for a large local archive, or a portable SSD if you regularly move large files and your devices support the connection it needs. Cloud storage suits files you want to reach across devices, provided you check which folders are included, the storage allowance, recurring billing and account recovery. For files that would be difficult to replace, keeping both a local copy and a separate cloud copy avoids relying on either route alone.
If photos, videos and documents take up substantial space, an external drive gives you a local backup destination. Microsoft Support describes external-drive backup with File History; Apple Support describes compatible disks for Time Machine. Check the drive's capacity and format against the computer you use.
If you need selected files on computers and mobile devices, consider a cloud account alongside the backup arrangement. Microsoft Support describes OneDrive folder backup across devices; check each service's included folders, storage allowance and account-recovery options.
A portable SSD may suit frequent copying of photo or video libraries. Samsung's stated T7 transfer speeds require a compatible USB 3.2 Gen 2 host and cable, so check the computers it will connect to before buying for speed.
For household photos and computer files, decide how you would recover a file after losing the original device. Then weigh the size of your archive, the devices that need access and how often you move large files.
| Concern | What to check | Who this matters to |
|---|---|---|
| Recovering files | Confirm how to restore a file or earlier version, and test a small restore. Decide where a separate copy will live. | If losing a computer would leave me without important photos or documents, I need a copy I can actually restore. About 27% of consumers put recoverability ahead of the other concerns here. |
| Capacity and ongoing commitment | Measure the files to be backed up and allow for growth. Compare drive capacity with cloud allowances and renewal terms. | A growing household photo library makes available space my deciding factor, while a cloud plan also means keeping track of recurring billing. Capacity and that commitment come first for about 27% of consumers. |
| Access across devices | Check supported devices, the drive connector and format, or which cloud folders are included. | When I switch between a computer and other devices, I need the files I use to be accessible on each one. About 20% of consumers primarily need that cross-device access. |
| Portable transfers | Check the SSD's interface and the computer's port and cable before relying on a stated maximum speed. | Regularly copying a large photo or video library makes transfer time and a drive I can carry especially important. Those are the primary needs of about 26% of consumers. |
OneDrive folder backup covers folders selected in its settings, not necessarily every place you keep photos or documents.
Check Desktop, Documents, Pictures and any separate photo libraries individually. Restore a test file before relying on the setup.
Apple Support says a Windows-formatted disk needs reformatting for Time Machine; erasing it removes the files already on it.
Copy existing files elsewhere first, then confirm the disk format and backup arrangement you intend to use.
Samsung says the T7's maximum transfer figures require a USB 3.2 Gen 2 host and cable with UASP support. A different connection may limit transfer speed.
Check the ports on each computer you will use and whether you have the appropriate cable.
Losing access to the account can prevent you from reaching its copy of your files. Google, Apple and Microsoft each describe recovery methods or limitations that depend on account setup.
Review your recovery email, trusted devices or numbers and any available recovery contact before treating a cloud account as your only separate copy.
The Expansion portable hard-drive line is a local-storage option for a household archive.
The My Passport USB-C family is relevant if you are considering an external-drive backup for Windows or Mac.
The portable T7 SSD line is relevant to people who repeatedly transfer large files.
OneDrive is a cloud route for selected PC folders that you also want to reach on other devices.
iCloud+ is a cloud-storage route for households using Apple devices.
These portable SSDs and hard drives are options for keeping a local copy of household files. Choose the capacity and connection for your computers; use a separate cloud copy as well if you do not want to rely on the local drive alone.

Consider this 2TB portable SSD for a local copy you need to carry between compatible devices. Confirm the connector and operating-system support for your computers, and check write performance if frequent backup transfers are a deciding factor.

This 4TB portable hard drive is an option for a local household-file archive. The title specifies USB 3.0; check your computer's connector and the disk format needed by your backup software, particularly if you will use it with a Mac.
Yes, if the drive is prepared as a compatible Time Machine backup disk. Apple Support says a Windows-formatted disk must be reformatted first, which erases its existing files; APFS or APFS Encrypted is its preferred format.
Yes. Microsoft Support says File History lets you select an external drive or network location for backups and restore saved file versions. Connect and configure the destination before relying on it.
Compare the space available for the files you will keep there, which folders or services use that space, the billing terms and account recovery. Microsoft lists a 100GB Microsoft 365 Basic allowance, while Google says an account includes up to 15GB shared across Drive, Gmail and Photos; check the plan that applies to your account.
If you lose account access, you may be unable to reach the cloud copy when you need it. Google advises keeping a recovery email current, Apple offers recovery contacts, and Microsoft describes limits when two-step verification methods are unavailable.
Consider encryption if the drive could be lost or stolen or holds sensitive files, while checking how the chosen drive or software handles recovery. The Information Commissioner's Office notes that losing a private key can make encrypted information inaccessible, so keep any required recovery material safely available.
