Home archive builders
If your full photo and video export will stay mainly at home, allow for a growing library and a repeatable copying routine. The National Cyber Security Centre also advises keeping a backup disconnected when it is not needed.
Who needs this storage?
Multi-device photo keepers
If you need to read the copy on more than one computer or another compatible device, check its connector and file system before loading files. Apple identifies exFAT as a Windows-compatible option for a data drive used with a Mac.
People who carry their backup
If the copy travels with you, a compact drive may be easier to handle than a desktop model. Check any physical-protection claim for the exact model, and keep another copy separate from the drive you carry.
What matters when choosing?
For a substantial photo library, establish the size of the local export before comparing drives. Then decide whether capacity, carrying the copy, access from your devices or recovery after a loss is your main constraint.
Portable SSD
Consider it when: You regularly carry or transfer a large copy between compatible devices.
Trade-off: Quoted speeds depend on the host, cable and supported USB mode; physical protection varies by model.
Desktop hard drive
Consider it when: Your priority is a large archive kept beside a home computer.
Trade-off: It needs a suitable place and external power, and a permanently connected copy is less isolated from a computer incident.
Portable hard drive
Consider it when: You want to carry an archive drive but do not need the quoted speeds of a particular SSD.
Trade-off: Check the chosen model’s capacity, connection and power requirements rather than applying desktop-drive specifications to it.
USB flash drive
Consider it when: You need a selected album, a hand-off copy or storage for a smaller library.
Trade-off: Check whether the exact drive can hold and reopen the files you intend to copy, especially large videos.
Separate cloud copy
Consider it when: You want an off-site copy alongside a local backup you can inspect.
Trade-off: You still need to understand the service’s export process and check that files can be recovered.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable capacity | Measure the downloaded export, including videos, and allow space for growth and a fresh copy. Check the capacity of the exact variant. | If my whole library must fit on one archive drive, I need room beyond today’s export. Around 36% of consumers would put capacity first. |
| Portable transfers | Check the drive connection, supplied cable and host USB capability before relying on a quoted maximum speed. | When I regularly move the copy between places, carrying it and completing transfers conveniently matter most; around 29% of consumers would make portable transfers their primary concern. |
| Device compatibility | List the devices that must access the drive and check their ports, file-system requirements and backup software before formatting. | I need to open the same files on my intended devices, not merely plug the drive in. For around 21% of consumers, compatibility would be the deciding concern. |
| Recovery after loss | Keep a separate copy, disconnect a local backup when appropriate, and try opening backed-up photos and videos. | If my computer or connected drive is affected, I want another copy I can actually use; recovery would come first for around 14% of consumers. |
Backup mistakes to avoid
-
Treating one drive as the entire backup plan
The National Cyber Security Centre describes incidents in which ransomware affected both original files and connected backups. One drive can also be lost or fail.
Maintain another separate copy, disconnect a local backup after updating it when practical, and periodically open files from the backup.
-
Matching drive capacity to the cloud-library figure
The downloaded copy may include videos and other exported files, while formatting leaves less usable space than the labelled capacity.
Measure the local export where possible and leave room for additions and a replacement copy.
-
Reformatting after loading the archive
Apple warns that formatting a disk erases its files. Changing the file system of a drive holding the only local copy puts that copy at risk.
Decide which devices and backup tools must use the drive before copying files. If a format change is necessary, secure another usable copy first.

Assuming a portable SSD meets every headline claim
Samsung says the T7 Shield’s quoted speed depends on compatible host hardware and cables. Its physical-protection claims have specific test conditions and warranty exclusions.
Check the precise model, connection, included cable and warranty terms; do not use a ruggedness claim in place of a second copy.
Brands to consider for photo backup storage
Samsung
The T7 Shield line is a portable SSD option when a compact additional copy needs to travel.
- Samsung lists USB 3.2 Gen 2 and 1TB, 2TB and 4TB T7 Shield variants, with quoted sequential speeds up to 1,050MB/s read and 1,000MB/s write.
- Those speeds depend on the host setup. Samsung’s IP65 and drop-resistance claims use controlled tests, and liquid, dust and drop damage are excluded from its stated warranty coverage.
Crucial
The X10 Pro is a portable SSD line worth checking if format and USB-C host compatibility will determine your workflow.
- Crucial says the X10 Pro ships formatted as exFAT and lists other file systems to which it can be reformatted.
- Crucial warns that reformatting loses data; its full USB 3.2 Gen 2x2 performance requires a compatible USB-C host.
Seagate
Its desktop drive lines are relevant to a large archive kept mainly at home.
- Seagate describes scheduled backup and file mirroring for One Touch Hub, and lists external power and capacities from 4TB to 28TB for Expansion Desktop.
- Seagate says Expansion Desktop needs reformatting for Time Machine compatibility. Check software and power requirements for the specific line rather than assuming they are shared.
WD
My Book is a desktop storage line to consider when archive capacity matters more than carrying the drive.
- Western Digital lists My Book family capacities reaching up to 26TB.
- Capacity alone does not protect the archive: keep another separate copy and check that backed-up files can be opened.
Joybuy storage choices for an additional local copy
These portable SSDs, portable hard drives and desktop hard drives are options for keeping a local copy of a photo library. Match the capacity to your downloaded files, then check the intended devices and keep another copy separate.

Common questions
How much capacity does a large photo library need?
Choose capacity from the size of the downloaded library, including videos, and leave room for additions and a fresh copy. The labelled drive capacity will not all be usable after formatting, as Crucial notes in its storage guidance.
Can I use one photo backup drive with both Mac and Windows?
Yes, if the drive’s format and your intended backup workflow support both computers. Apple identifies exFAT as a Windows-compatible format on Mac; check your backup software before choosing it, because formatting a drive erases its files.
How do I get photos out of a cloud service before backing them up?
Use the export or download options for your particular service, then inspect the local files before sizing a drive. Google Account Help describes downloadable data exports, Apple Support explains downloading iCloud originals, and Amazon Customer Service documents browser downloads of selected photos and videos; check your account’s current options rather than assuming a whole library can be downloaded in one step.
Is one external drive enough to protect my photos?
No: one drive provides an additional copy, but not protection against every loss affecting that drive. The National Cyber Security Centre advises separation between copies, including keeping a backup offline or disconnected when it is not in use; test that you can open files from it too.
Can I back up a Mac Photos library to an external drive?
Yes. Apple Support recommends a local backup even if you use iCloud Photos, and describes Time Machine or manually copying the library to external storage. Back up referenced files stored outside the Photos library separately, and do not use the drive holding the library as its Time Machine backup destination.
