For a growing archive copied mainly from a computer, consider a portable HDD; if you move large folders frequently, an SSD offers faster transfers, though Which? says SSDs are usually more expensive. A USB stick is more suited to selected file transfers than a growing archive, while automatic cloud backup can sit alongside a separate local copy. Before buying a drive for phone transfers, check the connector, format, power requirements and transfer route for your particular device.
If photos, videos and documents are accumulating on a computer, you may want enough space for a separate, current copy rather than prioritising rapid transfers. Which? identifies portable HDDs as a route for long-term computer-file backup; the National Cyber Security Centre advises keeping important data in a separate safe location.
If the immediate task is clearing space on an iPhone or Android phone, establish how files will reach the drive before choosing a capacity. Apple sets requirements for direct iPhone storage access, while Google documents an Android-to-computer transfer using a data-capable USB cable.
If remembering to copy new photos is the difficulty, automatic cloud photo backup may help keep recent files available across devices. Google Photos describes automatic saving to a Google Account; the National Cyber Security Centre also recognises removable media as a place for a separate backup copy.
Decide whether the priority is a growing local archive, frequent transfers, a workable phone connection or automatic copies; each points to a different check before purchase.
| Concern | What to check | Who this matters to |
|---|---|---|
| Space for an archive | Check the drive capacity against the files you intend to copy, and whether it connects to the computer used for backups. | When family photos, videos and documents keep accumulating, I need room for a separate local copy. About 33% of consumers put archive capacity first. |
| Frequent transfers | Check the drive and computer connections together; a quoted SSD speed depends on the host, port, cable and configuration. | If I regularly move large photo or video folders, waiting for each copy matters more to me than it would for an occasional backup. Faster transfers are the primary need for about 25% of consumers. |
| Device compatibility | For direct iPhone access, check the connector, single-partition format and power setup. For Android-to-computer transfer, use a data-capable cable. | A drive is little use to me if I cannot move files from the phone or computer I already own. About 25% of consumers chiefly need a workable device-to-drive route. |
| Automatic copies | Check that photo backup is enabled on the intended account and that a separate copy exists for important files. | With new photos arriving often, I want copies made without a manual transfer each time. Keeping backup current automatically comes first for about 17% of consumers. |
An external drive can itself be lost, damaged or unavailable. The National Cyber Security Centre describes a backup as a copy of important data kept in a separate safe location.
Keep another separate, current copy of irreplaceable files and check that you can open the copies you have made.
Apple requires a single data partition and a supported format for iPhone external-storage access. It also notes that external hard drives often need their own power when connected to an iPhone.
Identify your iPhone connector, then check the intended drive, adapter, format and power arrangement before ordering.
A compatible adapter, powered hub or power adapter may be needed for the chosen setup.
Google notes that not every USB cable transfers files, so a cable can interrupt an otherwise workable phone-to-computer route.
Use a data-capable cable, unlock the phone and select File transfer before moving or deleting the original photos.
Apple specifies APFS or Mac OS Extended (Journaled) for an external Mac Photos library. That requirement is distinct from choosing a format for general files shared between devices.
Decide what the drive will hold before formatting it, and copy existing files elsewhere first if they must be kept.
Reformatting can erase files already on the drive.
The Portable SSD T7 line is relevant when compact local storage and frequent transfers are priorities.
Its portable SSD lines offer local photo and file storage in a carryable format.
The Ultra Touch portable HDD line is positioned for local photo, video and file storage.
My Passport models are relevant to computer-first portable backups, but their format depends on the particular version.
These portable SSDs and HDDs are options for keeping local copies of household photos and files. Choose a computer-based or direct-phone transfer route only after checking that it works with your devices.

Consider this local-copy option if you want SSD storage for a growing collection of files. Its product name specifies 4 TB, USB Type-C and USB 3.2 Gen 2; check the transfer route and format for your particular phone before relying on direct connection.

This portable HDD is a Mac-oriented option for a sizeable local file archive. Check the intended format and software requirements if the same drive must also work with Windows, and confirm the setup separately before connecting it directly to a phone.

Consider this smaller-capacity portable option if frequent file transfers matter more to you than keeping a larger local archive. Its product name specifies 1 TB and USB Type-C 3.2 Gen 2; confirm the required format, adapter and power setup before planning a direct-phone workflow.

This portable HDD offers a local-copy option for a computer-based household archive. The product name specifies 4 TB and USB 3.0; check the format needed for a Mac or other device before use, and confirm compatibility before buying it for direct phone transfers.

Consider this SSD if you want a 2 TB local copy that you can carry between file-transfer locations. Check its connector, format and compatibility with your particular phone or computer before choosing a direct-device setup.
Yes, if the iPhone, connector or adapter, app and drive setup work together. Apple says external storage accessed by iPhone must have a single data partition in a supported format; some external HDDs also need their own power. Check those requirements for the drive and iPhone you plan to use.
Transfer the files to a computer with a USB data cable, then copy them from the computer to the external drive. Google advises unlocking the phone and selecting File transfer, and notes that not all USB cables carry data. If you want to connect a drive straight to the phone instead, check your phone manufacturer's device-specific requirements first.
Check the two tasks separately rather than assuming any iPhone-readable format suits a Photos library. Apple lists APFS, APFS (encrypted), Mac OS Extended (HFS+), exFAT, FAT32 and FAT for iPhone external-storage access, with a single data partition. For an external Mac Photos library, Apple specifies APFS or Mac OS Extended (Journaled).
