For a large local photo archive, consider a portable hard disk drive (HDD) if you need to carry it, or a desktop drive if it will stay at one desk. A portable solid-state drive (SSD) is worth considering for frequent transfers between devices, but its advertised speed depends on the computer port and connection. Whichever drive you choose, set up a backup you can restore and keep another copy separate from the computer; cloud storage can serve as that complementary copy.
An external drive can hold files outside the laptop and provide a destination for regular backups. Microsoft Support describes File History backups to an external drive or network location; Mac owners can check whether their chosen drive works with Time Machine.
Allow for the photos you already have and future backups, then choose a routine you can restore from. The UK National Cyber Security Centre advises backing up important files, including photos and documents, and checking that restoration works.
A portable SSD may suit frequent transfers of large photo or video files. Check the ports on every device you intend to use: the maximum speeds claimed for models such as Samsung’s T7 Shield and Crucial’s X10 Pro depend on compatible connections.
Start with where the files will live and how much space the backup needs, then check the connection, backup method and separate-copy plan.
| Priority | What to check | Your needs |
|---|---|---|
| Portable HDD | Compare capacity with your archive and planned backups. Check the drive’s format and backup-software compatibility for your computer. | I want to carry a local copy of photos and documents, but repeated large-file transfers are not my main task. |
| Portable SSD | Check the laptop’s USB mode and cable against the exact drive’s speed requirements. Compare capacity with the files you need to carry. | I regularly move large photo or video folders between devices, so connection compatibility matters as much as the advertised speed. |
| Desktop drive | Check the exact model’s capacity, connection, power requirements and backup setup. Seagate UK lists One Touch Hub capacities including 4TB, 12TB, 16TB and 20TB. | Most of my household archive will stay at one desk, and portability matters less than having room for the files. |
| Cloud copy | Check which folders are backed up, the available account storage and whether you can restore the files. Google says its standard account allowance is up to 15GB shared across Drive, Gmail and Photos. | I want another copy that is not left attached to my computer, alongside a local backup I can check. |
| Backup capacity | Count current files and allow for future copies. For Time Machine specifically, Apple Support recommends a backup disk with at least twice the Mac’s storage capacity. | My photo collection is growing, and I do not want the backup disk to fill as soon as I start using it. |
| Backup method | Confirm which folders are copied and practise restoring a file. Microsoft Support describes regular File History copies; check the chosen drive and format for your intended Mac or Windows backup method. | I would rather use a repeatable backup routine than rely on remembering to copy folders manually. |
| File protection | Keep another recoverable copy and disconnect a local backup when it is not in use. The National Cyber Security Centre advises against leaving a backup device permanently connected. | These photos and documents would be difficult to replace, so moving them off the laptop alone is not enough. |
A drive permanently connected to the computer may also be exposed if ransomware affects that computer.
Follow the National Cyber Security Centre’s advice to make regular backups, check that files can be restored and avoid leaving the backup device permanently connected.
Samsung says its T7 Shield’s stated maximum speed needs USB 3.2 Gen 2, a compatible cable and UASP. Crucial says the X10 Pro needs a compatible USB-C host for full USB 3.2 Gen 2x2 performance.
Check the computer port’s specification, not just its connector shape, along with the cable needed for the exact drive.
A format suitable for moving files between computers may not be suitable for a Time Machine backup. Apple Support warns that erasing a storage device deletes its contents.
Copy existing files elsewhere before changing the format, and decide whether the drive is for Time Machine, Windows backups or general file transfers.
A model’s stated resistance applies under its test conditions; it does not make the files recoverable if the drive is lost or damaged beyond those conditions.
Read the exact model’s protection and warranty terms, and keep a separate backup of important files.
Samsung’s T7 portable SSD range is relevant when a compact drive and frequent file transfers matter; the T7 Shield adds stated physical-protection features.
The One Touch family covers portable drives and desktop hubs for storing photos, videos and documents.
The Extreme Portable SSD range is relevant to people carrying files or moving them between devices.
Crucial’s X10 Pro is a portable SSD option for large-file transfers when the computer has a suitable USB-C host.
These portable HDDs and SSDs are options for keeping a local photo archive or moving files between devices. Choose the capacity and connection for your own backup setup, and keep a separate recoverable copy of important files.

Consider this portable HDD for a Mac-focused local archive. Its title specifies 5TB; check the exact file format and Time Machine setup you intend to use before making it your backup drive.

This portable HDD is an option for a 5TB local file archive. If you plan to use it for Mac backups or share it between operating systems, confirm the required format and backup method first.

The 4 TB portable SSD is worth considering when you regularly carry or transfer large file collections. Its title specifies USB 3.2 Gen 2; check your computer port and cable against the exact model’s performance requirements.

This 2TB portable HDD may suit a smaller local file collection. Compare that capacity with the files you need to back up, and confirm compatibility with your operating system and backup method.

Consider this portable SSD for a 4 TB collection you need to move between devices. Its title specifies USB 3.2 Gen 2x2; confirm that your computer supports that mode rather than relying on the USB-C connector shape alone.
Apple Support recommends a backup disk with at least twice the Mac’s storage capacity. That is guidance for planning a Time Machine backup, not a capacity rule for every external drive or file-transfer task.
Yes, for general file transfers if the drive has a suitable format, but do not assume the same setup will work for Time Machine. Apple Support identifies exFAT as a Windows-compatible format for volumes over 32GB and says Time Machine cannot back up to a disk formatted for Windows; APFS or APFS Encrypted is preferred for a Time Machine disk.
Not necessarily: Microsoft Support describes regular backups through Windows File History, and Mac users can use Time Machine with compatible storage. Check that your chosen method copies the folders you care about, then try restoring a file.
No. The National Cyber Security Centre advises checking that backups can be restored and not leaving the backup device permanently connected to the computer, where ransomware could reach it.
Cloud storage can provide a separate copy, but check which files are backed up, your available capacity and how to restore them before relying on it. Google says its standard account includes up to 15GB shared across Drive, Gmail and Photos; a local drive remains an option when you also want a copy under your direct control.
