Choose a portable HDD or desktop drive when a growing local archive is the main priority; consider a portable SSD when you regularly move large files and carry the drive. Cloud storage can provide another location and access across devices, but check your storage allowance and keep a separate backup: no single drive or account should be your only copy.
If family photos, documents and computer files are taking up more space, you need a local backup destination with room for the collection to grow. Microsoft Support identifies large files and large numbers of files as reasons to consider external or network storage.
If you often carry a drive or transfer large media files, check its connection requirements and the protection specified for the exact model. Samsung notes that its T7 Shield's stated maximum speeds depend on a compatible host, cable and USB mode.
If you would rather back up routinely than remember to copy folders, start with the devices and software you use. Microsoft Support describes regular backups through File History, while Apple Support explains how to use external storage with Time Machine.
Decide where each copy will live, then check that the capacity and connection suit the devices you actually use.
Choose when: You want a carryable local destination for a growing photo and document archive.
Bear in mind: A drive left connected can be affected alongside an infected computer; disconnect a backup when it is not in use, as the National Cyber Security Centre advises.
Choose when: You frequently transfer large files or carry your local backup between locations.
Bear in mind: A quoted maximum speed is conditional on the connection. Samsung says its T7 Shield speed rating requires a compatible host, cable and UASP mode.
Choose when: The archive will stay at a desk and capacity matters more than carrying the drive.
Bear in mind: Check the exact model's power and connection requirements before planning a place for it.
Choose when: You need a copy away from the home computer or access from signed-in devices.
Bear in mind: Uploads need an internet connection, and Google Photos says original-quality backups count towards Google Account storage.
| Concern | What to check | Who this matters to |
|---|---|---|
| Room to grow | Compare the space already used by your files with the drive capacity and the backup history you want to retain. For Time Machine, Apple Support advises a disk with at least twice your Mac's storage capacity. | If my family's photo and document collection keeps growing, I need room for complete backups rather than just today's files. Around 37% of consumers would put capacity first. |
| Device and software fit | Check ports, cable ends, drive format and your intended backup application. Test direct USB access on the actual phone or tablet before making it your routine. | I want backups to run reliably on the computers and devices I own, without discovering a setup conflict later. For around 27% of consumers, that workflow would be the primary concern. |
| Transfers and carrying | Match the drive's stated connection requirements to your computer and cable. Check the exact model's protection claims and warranty exclusions. | When I move large photo or video collections between places, I care about the connection and what happens while the drive is being carried. Around 27% of consumers would prioritise those needs. |
| A separate location | Check what counts towards cloud storage, protect account access and keep a local backup disconnected when it is not in use. | If something happens to the computer and the drive beside it, I still want another copy I can reach. That would be the leading concern for around 9% of consumers. |
A connected drive can be affected alongside an infected computer, while a drive kept beside the computer does not protect against every incident at home, according to the National Cyber Security Centre.
Keep more than one copy, disconnect a backup drive when it is not in use and consider a securely protected copy in another location.
Samsung says the T7 Shield's stated maximum speeds require a compatible USB 3.2 Gen 2 host and cable, with UASP enabled. A different connection may not deliver that figure.
Check the computer port, the supplied cable and the exact drive's requirements before making transfer speed the deciding factor.
Apple Support says a Photos library cannot be stored on a storage device used for Time Machine backups. Moving the library there would create a setup conflict, not an independent backup.
Plan a separate destination for the Photos library and retain the original until the new arrangement is working.
Google Photos says original-quality photos and videos count towards Google Account storage. An online copy also needs protected account access.
Check your available storage and account-recovery settings, and retain a separate local copy.
Western Digital presents portable My Passport-style drives and other home-backup storage for people planning local computer backups.
Seagate's One Touch support materials address portable computer backups, while its Expansion desktop range addresses desk-based archiving.
Samsung's portable T7 Shield SSD is relevant when carrying the drive and transferring large files are priorities.

Apple Support advises a backup disk with at least twice your Mac's storage capacity. It also says to use the Time Machine disk for backups rather than ordinary file storage.
Yes. Microsoft Support says File History can make regular backups to an external drive or network location; check that the folders you want are included.
Files by Google supports copying and moving files on recognised USB storage with Android 7.0 and later. Check recognition on your actual phone or tablet, including its cable, adapter and drive, before depending on direct backup.
No, not in the arrangement described by Apple Support: it says a Photos library cannot be stored on a device used for Time Machine backups. Plan a separate destination for the library.
Disconnect a backup drive when it is not in use. The National Cyber Security Centre warns that connected backup storage can be affected alongside an infected computer; store the disconnected copy securely.
