People protecting irreplaceable photos
You want a copy you can restore if a device fails or a file disappears, not just somewhere to move it. The UK National Cyber Security Centre describes a backup as a copy kept in a separate safe location.
Who this guide is for
People with a growing full-device library
You need enough room for your actual photo and video collection, and need to distinguish moving files from keeping a backup. Which? addresses both full-device storage and photo backups in its consumer guidance.
People moving files between devices
You carry selected files between a phone and computers, or between home and work, so connector and file-format compatibility matter. Apple Support, Kingston Technology and Files by Google each outline checks for their supported devices or formats.
What to consider
Portable SSD
Consider it when: you regularly carry and transfer a substantial local library.
Bear in mind: the host port and cable affect whether the connection suits your needs, and a portable drive is not a separate backup if it travels with the only original copy.
Portable hard drive
Consider it when: you want a larger local copy and repeated fast transfers are not your main priority.
Bear in mind: check the exact connector and backup-software requirements; Apple says a disk may need reformatting for Time Machine, which can erase existing files.
USB flash drive
Consider it when: you need to hand over or carry selected files between compatible devices.
Bear in mind: a transfer stick is not automatically a maintained backup of your whole library; check its usable capacity, connector and supported file formats.
Cloud storage
Consider it when: online access or automatic copying suits your devices and connection.
Bear in mind: extra storage can involve a continuing subscription, and Apple says iCloud Photos deletions are reflected across devices using that library.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Recoverable copy | Keep a separate copy and open or restore sample files; the UK National Cyber Security Centre advises keeping important data in a separate safe location. | I want to recover valued photos if the original device is lost or files disappear. Around 28% of consumers put recoverability first. |
| Device and format fit | Match the connector, power and file format to each device; check the requirements of the intended backup software before formatting. | I use a phone as well as computers, or need a drive for a particular backup workflow. Around 22% of consumers prioritise compatibility across devices. |
| Capacity for the library | Compare the exact drive capacity with the files you plan to copy; Kingston notes that usable flash storage can be less than the stated capacity. | I need room for my full photo and video collection, not just a small selection of files. Around 22% of consumers put capacity first. |
| Carrying and transfers | When transfer time matters, check the drive, host port and cable together. Samsung says the T7 Shield’s resistance rating is based on controlled testing and that resistance can vary with conditions. | I regularly carry files between locations and want the connection to suit my devices. Around 17% of consumers prioritise portability and transfers. |
| Payment and access | Compare the storage you need with a local device or a cloud plan’s ongoing billing; check what the service copies and how you can retrieve it. | I am deciding between managing local hardware and paying for continuing online storage. Around 11% of consumers put the payment model first. |
Common buying pitfalls
-
Calling the only surviving copy a backup
Moving files can free device space without leaving a separate copy you can restore. The UK National Cyber Security Centre describes a backup as data kept in a separate safe location.
Check what was copied, try opening or restoring sample files, and keep another copy of important items separately.
-
Assuming photo synchronisation is an independent backup
Apple says a deletion in iCloud Photos is reflected on other devices using that library.
Keep another copy of valued photos and check how the service handles backup and deletion before clearing space on your device.
-
Formatting a drive that already contains files
Apple says a disk may need reformatting for Time Machine, and reformatting can permanently remove existing data.
Copy existing files elsewhere first, then choose the drive’s purpose and check the required format before formatting it.
-
Choosing by plug shape or headline speed alone
A matching connector does not establish that a phone can power and read a drive, or that a host can use its stated interface speed.
Check the exact device, port, cable, format and power requirements. Apple Support notes that an external hard drive connected to an iPhone may need additional power.
Relevant brands and product lines
Samsung
The T7 Shield is one example of a portable SSD for carried files and frequent transfers.
- Samsung specifies USB 3.2 Gen 2 and an IP65 rating based on controlled testing for the T7 Shield.
- Samsung says resistance can vary with conditions and liquid or dust damage is not covered by its warranty; the rating is not a guarantee against damage.
Western Digital
WD Elements Portable variants are an example of local storage for photos and files.
- Western Digital lists a 2TB Elements Portable variant with USB 3.2 Gen 1/USB 3.0 connectivity.
- Check the exact capacity and connector for the variant you are considering; specifications should not be assumed to apply to every WD drive.
Seagate
Expansion Portable is a USB-powered hard-drive line for local files.
- Seagate’s datasheet identifies a 2TB STKM2000400 variant and a USB 3.0 cable.
- The datasheet says reformatting is required for Time Machine and that its Rescue service is not available in all countries; check the current package terms.
Kingston
DataTraveler Exodia M illustrates a USB-A stick for transferring selected files.
- Kingston lists a 128GB USB-A version of the DataTraveler Exodia M.
- Kingston notes that usable file capacity is less than the stated capacity; a transfer stick should not be mistaken for a maintained full-library backup.
Apple
iCloud+ is a cloud-storage option for supported Apple photo and device workflows, rather than a portable drive.
- Apple lists paid storage plans and access to photos across devices.
- Apple says iCloud Photos deletions propagate across devices using the library and recommends keeping backup copies of the photo library.

Frequently asked questions
If I move my photos to a drive and delete them from my phone, are they backed up?
Not if that drive then holds the only remaining copy. Keep another copy separately and check that you can open or restore sample files before deleting the originals. The UK National Cyber Security Centre describes a backup as a copy kept in a separate safe location.
Can I use the same exFAT drive for manual Windows–Mac transfers and Mac Time Machine?
Do not assume that a format used for manual file transfers will also suit Time Machine. Apple specifies its requirements for Time Machine disks and says reformatting a Windows-formatted disk may permanently remove its data, so decide the drive’s purpose and copy existing files elsewhere before formatting.
Will an external USB drive connect directly to my phone?
That depends on the phone and drive. Apple lists supported connection, partition and format requirements for iPhone storage, and notes that an external hard drive may need additional power. Files by Google documents USB storage access for devices running Android 7.0 or later; check the specific phone and drive before buying.
Does iCloud Photos protect pictures from accidental deletion?
It is not an independent copy: Apple says a deletion in iCloud Photos is reflected on other devices using that library. Keep another copy of valued photos and check the service’s recovery and deletion behaviour.
How do I choose a capacity for photo backups?
Compare the capacity of the exact drive or cloud plan with the files you intend to keep, and allow for the space used by the device or service itself. A selected-file transfer and a full-library backup need not require the same amount of storage.
