Choose an external hard disk drive (HDD) for a large family archive that will mostly stay at home; consider a portable solid-state drive (SSD) if you carry the copy regularly or transfer large photo and video folders often. Add cloud storage when you want a copy away from your computer and home drive, rather than assuming either location alone protects every file. Before moving photos, check capacity, device connections and file format, and make sure freeing computer space will not leave you with just one copy.
If photos and videos are filling a computer, allow room for both the files you have now and future copies. Which? identifies full computer storage and photo backup as reasons to consider an external drive; moving files off the computer still calls for another separate copy.
A drive carried between a Windows PC, Mac, tablet or phone needs more than a connector that fits. Check the cable, file format, device support and power requirements before relying on it across your devices. Apple Support sets additional format and partition conditions for external storage connected to an iPhone.
For family documents and photos you could not readily recreate, the location of each copy matters as much as the drive choice. The National Cyber Security Centre describes a backup as a copy kept in a separate safe location; a local drive and a cloud copy can serve different locations.
Start with the size of the archive and how often you will move it, then check where the other copy will live and which devices must open it.
| Concern | What to check | Who this matters to |
|---|---|---|
| Room for a growing archive | Measure the folders you plan to copy, including videos, and leave room for future files and retained backups. Compare that need with the drive capacity and the usable space shown by your device. | If family photos keep accumulating, I need space for the collection without repeatedly moving parts of it elsewhere. About 33% of consumers put archive capacity first. |
| Separate, recoverable copies | Check which folders are copied, how often copies are made and whether you can restore a file. Keep another copy in a separate safe location; the National Cyber Security Centre cautions that cloud and local backups are not ransomware-resistant by default. | When documents or photos would be difficult to replace, I want to know that losing access to my computer would not mean losing every copy. For about 27% of consumers, a separate, recoverable copy is the primary need. |
| Carrying and transferring files | Compare the drive format and its stated protection conditions with how you will carry it. Check the host port and cable before relying on an SSD’s maximum rated speed. | If I move a backup between places or regularly copy large folders, carrying the drive and completing transfers conveniently matter most. That is the main concern for about 20% of consumers. |
| Device compatibility | Confirm connectors, cables, file format and power needs for each intended device. Apple Support notes that formatting erases files and sets specific format and partition requirements for iPhone external storage. | To use one drive across a computer and mobile devices, I need to be sure each can read it before loading my files. Compatibility comes first for about 20% of consumers. |
If the files are moved and the originals deleted, the drive may hold the only copy. The National Cyber Security Centre defines a backup as a copy stored in a separate safe location.
Keep another copy apart from the working files, and occasionally open or restore a few photos and documents to check it.
A file format chosen for sharing between Windows and Mac may require changing how a drive is formatted. Apple Support warns that formatting a disk or volume erases its files.
Decide which devices need access before loading the archive. Save any files already on the drive to another verified location before reformatting.
The connector shape does not establish the host’s interface speed or mobile-device support. Samsung says the T7 Shield’s maximum rated speeds require a compatible USB 3.2 Gen 2 host and cable, with UASP mode enabled.
Check the intended device’s port specification, the cable and external-storage support before choosing a drive for its rated speed.
Samsung’s IP65 and drop claims for the T7 Shield relate to stated tests; Samsung also says liquid, dust and drop damage are not covered by its warranty.
Consider those conditions when carrying the drive, but keep another copy of files you cannot replace.
Seagate’s Backup Plus Portable line is relevant to a household considering a higher-capacity portable HDD for scheduled local copies.
Samsung’s T7 Shield line is relevant when a portable SSD’s stated transfer speed and transport protection affect the choice.
Kingston’s XS1000 and Dual Portable SSD lines are relevant when compact storage must connect to equipment using USB-A or USB-C.
These portable SSDs and HDDs are options for keeping a local copy of family files and photos. Choose capacity for your own archive, and plan where a separate copy will be kept.

Consider this portable SSD if you regularly carry a local copy or move photo and video folders between computers. Its listed capacity is 2 TB and its interface is USB 3.2 Gen 2; check the intended devices, cable and file format before copying your archive.

This portable SSD suits a local-copy routine where the drive will be carried regularly, provided 1 TB covers the files selected for backup. Samsung states IP65 and a 3 m drop-test claim for this model under specified conditions, but says liquid, dust and drop damage are not covered by the warranty. Keep another copy and check the file format needed by your devices.

The 4 TB capacity makes this portable SSD an option when a family photo and video archive needs more local space. Its stated interface is USB 3.2 Gen 2x2; check whether your computer supports that interface before relying on the listed maximum transfer rate, and confirm the file format for each intended device.

This portable HDD is an option for a larger local archive that will mostly be backed up at home. It has 5 TB stated capacity. If you intend to use it with both Windows and Mac, confirm the file format before loading photos; Apple Support warns that reformatting erases files.

Consider this 5 TB portable HDD for a Mac-centred local archive. If the same files must also be opened on Windows, check the file format and any driver requirements for your intended setup before relying on cross-platform access. Keep a separate copy of important files.
An HDD suits a large local archive backed up mainly at home, while an SSD is worth considering when you frequently carry the drive or copy large folders. Which? describes HDDs as suited to long-term computer-file backup and SSDs as generally faster; neither drive type removes the need for another separate copy.
Yes, if its connection and file format suit both computers. Apple Support identifies ExFAT as a Windows-compatible format for volumes over 32 GB, but warns that formatting erases files. Check the format before placing your only copy on the drive.
Sometimes, provided the drive and connection meet the iPhone’s requirements. Apple Support says external storage must have one data partition and a supported format; an adapter or additional power may also be needed, particularly for an external HDD.
Cloud storage can hold a copy away from your computer, but it need not replace a local copy of important family files. The National Cyber Security Centre identifies both cloud storage and removable media as backup locations and cautions that neither cloud nor on-premises backups are ransomware-resistant by default. Check that the copies you rely on are recent and can be restored.
