Choose cloud backup for automatic phone-photo uploads and access across signed-in devices, a portable HDD for a sizeable computer archive kept mainly at home, or a portable SSD for frequent large transfers and a drive you carry. A USB flash drive is more useful for moving selected files than as your only archive. For photos you cannot replace, keep a separate backup copy, disconnect a local backup between updates, and check device compatibility before choosing a drive.
Where your photos live now, and how often you move them, should shape the backup you choose.
If most photos and videos begin on an iPhone or Android phone, automatic cloud uploads may take less routine effort than copying files manually. Google Photos supports automatic uploads to a signed-in account; for a drive-based alternative, check the phone’s connector, storage format and copying workflow. Keep another copy of important memories.
If a Windows PC or Mac already holds the family library, consider a portable HDD for a capacity-led local backup or an SSD when copying speed and frequent transport matter more. Which? describes HDDs as suited to long-term computer-file backup and SSDs as usually faster. Keep the archive and its backup as separate copies.
Frequent transfers between devices make a portable SSD worth considering. Which? notes the speed and resistance-to-knocks advantages of SSDs over HDDs, but the connection can limit a particular drive’s advertised speed. Check the port and cable on each device you intend to use.
Start with the device holding your photos, then match the destination to your archive size, copying routine and need for a separate recoverable copy.
| Priority | What to check | Your needs |
|---|---|---|
| Recoverable copies | Check that the backup contains the folders you expect and that you can retrieve files from it. The National Cyber Security Centre advises considering both an online backup and a storage device; it has also reported ransomware incidents affecting connected backup drives. | I do not want one failed, lost or affected device to hold the only copy of family photos. A local drive can be disconnected once its backup update is complete. |
| Archive space | Compare drive capacity with the existing library and planned additions. For cloud uploads, check the account’s available storage and quality setting: Google Photos says Original quality retains the captured resolution and counts towards Google Account storage. | My collection is growing, so the destination needs room beyond the files I am copying today. If original resolution matters, I need to check the cloud setting before a bulk upload. |
| Copying and carrying | Decide whether you are making occasional computer backups or frequently moving large videos. Which? says HDDs are typically slower and more susceptible to knocks than SSDs; check the host port and cable before relying on an SSD’s stated maximum speed. | For an archive that stays mostly at home, capacity matters more to me than quick transfers. If I carry files between devices often, copy time and handling become more important. |
| Phone and computer fit | Check the physical connector, power needs and file system against the intended device. Apple says external storage connected to an iPhone must have one data partition and use a supported format; some hard drives may also need additional power. | I want to know that my phone or computer can actually use the drive before choosing it. A matching USB connector alone does not settle the whole copying workflow. |
| Automatic uploads | Check whether the service uploads from your phone automatically, what account storage it uses and how you would retrieve the files. Google Photos supports automatic backup; UK government cloud-storage guidance advises checking service restrictions and access conditions. | Most of my pictures start on my phone, and I am unlikely to remember every manual copy. I still want a separate way to retain photos that would be difficult to replace. |
| Selected transfers | Check a USB stick’s capacity and connector against the files and devices involved. Which? describes USB sticks as a way to move files between computers; moving files is a different task from maintaining a recoverable archive. | I only need to carry a chosen set of photos or clips, not put the whole household collection on one small device. |
Loss, failure or an incident affecting a connected drive could leave no usable backup. The National Cyber Security Centre has reported ransomware incidents involving both original files and connected backup storage.
Keep another genuinely separate copy where practical, such as an online backup alongside a local one. Disconnect the local drive after its update and check that the copies can be retrieved.
An advertised maximum is conditional on the connection. Samsung says the T7 Shield’s stated maximum read and write speeds require a compatible USB 3.2 Gen 2 host and cable, with UASP enabled.
Check the exact drive interface, computer or phone port and cable together. Treat a speed figure as a model-specific specification, not a promise for every device.
A convenient way to carry selected files does not remove the risk of losing the only copy. Which? describes USB sticks as devices for moving files between computers.
Use a stick for limited transfers or an additional copy, while retaining a separate backup of the full collection.
Upload quality affects what is stored and how much account storage is used. Google Photos says Original quality keeps the captured resolution and counts towards Google Account storage; UK government guidance also warns that a suspended or cancelled account can affect access to data.
Choose the quality setting deliberately, check storage and service conditions, and keep a separate copy before depending on an account for irreplaceable media.
Duplicating or moving a large library also takes time, so plan how you would retrieve it before you need to.
These examples illustrate specifications and checks for particular product lines; a brand name alone does not establish that every model has the same features.
Samsung’s T7 Shield is a portable SSD line to consider when transferring large files between compatible devices.
The Expansion Portable 4TB is an example of a capacity-led portable HDD for a computer-based archive.
SanDisk is relevant to shoppers considering a USB stick for selected transfers or a portable SSD for local storage.
These drives cover portable SSDs for local storage and file transfers, a portable HDD for a computer archive, and a USB stick for selected transfers. Whichever you choose, plan a separate copy for important photos and videos.

This 1TB portable SSD is an option for moving photo and video files when that capacity fits your archive. Samsung UK states maximum speeds of 1,050 MB/s read and 1,000 MB/s write for this model, conditional on a USB 3.2 Gen 2 host and cable with UASP enabled. Check the file system and your phone’s copying workflow before relying on direct phone use.

Its stated 512GB capacity and dual connectors make it an option for carrying selected files between devices. The product name specifies USB 3.2 Gen 1 and advertises 570 MB/s read speed; that figure does not establish copying speed in every setup. Check your device’s connector and file-system workflow, and retain another copy of important files.
For photos you cannot replace, keep a separate copy rather than depending only on a cloud account. The National Cyber Security Centre advises considering both online backup and a storage device. Check the service’s storage and retrieval options, and disconnect a local drive when you are not updating it.
An iPhone can use compatible external storage, but the connection and drive format matter. Apple says the storage must have one data partition and use a supported format, including APFS, HFS+, exFAT, FAT32 or FAT. Check the connector or adapter and whether the drive needs additional power before planning a direct-copy routine.
Windows File History can make regular copies to an external drive or network location, according to Microsoft Support. Check that the folders containing your family photos and videos are included, then confirm you can retrieve files from the backup.
Google says its Original quality setting stores photos and videos at the captured resolution, and those uploads count towards Google Account storage. Select the quality setting you intend to use and check available storage before uploading a large archive.
