Choose a portable HDD if your main task is keeping a growing, longer-term photo archive; choose a portable SSD if you frequently transfer or work with large files and your devices can use its connection. Which? describes HDDs as suited to longer-term backup and SSDs as faster but usually pricier. A NAS can serve several devices at home, while cloud storage can provide an off-site copy, but whichever route you choose, keep irreplaceable files in another separate location.
If family photos, videos and documents are accumulating, you need room for them and a routine that keeps another copy somewhere separate. The National Cyber Security Centre advises storing backups apart from the original files.
If you frequently copy photos or video, transfer speed and the ports and cables on your devices matter alongside capacity. Check those connections before choosing a portable SSD for work away from home.
If phones and computers all need regular backups, consider whether you can manage a shared NAS and its separate backup destination, or a cloud account with suitable storage and restore options.
Start with the job the storage must do, then decide where its second copy will live. A desktop drive can be a backup destination kept at home; a card reader helps move photos from a card but is not a backup destination by itself.
Choose when: A longer-term local archive matters more than frequent fast transfers.
Trade-off: Which? describes SSDs as faster; the HDD still needs a separate backup copy.
Choose when: You regularly move or work with large files away from home.
Trade-off: Which? says SSDs are usually pricier than HDDs, and transfer speed depends on the connection used.
Choose when: Your local backup can stay mainly at home rather than travel with you.
Trade-off: Keeping it beside the computer does not provide an off-site copy.
Choose when: Several household devices need central storage or repeatable local backups.
Trade-off: You must manage the system and another backup destination. Synology warns that RAID failures can still cause data loss.
Choose when: You want an off-site copy that can update without connecting a drive each time.
Trade-off: Check account access, restoration and subscription terms; a connected cloud account is not immune to compromise.
| Concern | What to check | Who this matters to |
|---|---|---|
| Archive capacity | Check the space your files need as they grow and where you will keep a separate copy. | If family photos and videos are accumulating, I need room for a lasting archive more than faster everyday transfers. Roughly 33% of consumers would put archive capacity first. |
| Portable transfers | Check the drive’s stated read and write speeds against your device’s port and cable support. | When I frequently move large photo or video files, waiting for transfers and carrying the drive matter to my choice; around 25% of consumers would prioritise this need. |
| Shared access | Check supported backup applications, how to restore files and where a separate NAS backup will go. | With files on several phones and computers, I want a repeatable way to bring them together. About 17% of consumers would make shared access their primary concern. |
| Off-site recovery | Check automatic backup, account recovery and how you would retrieve files; retain a separately protected copy. | If I might forget to connect a drive, I need a current copy away from my computer that I can restore. Roughly 25% of consumers would put off-site recovery first. |
A lost or failed drive can take its only copy with it. The National Cyber Security Centre also notes that ransomware can affect backups left connected to a computer or network.
Keep another copy in a separate location and, where practical, avoid leaving every backup continuously connected.
The connection can limit SSD transfer speed, while a file system may let one device read a drive without writing to it. Samsung’s stated T7 Shield speeds, for example, require a compatible host, cable and UASP support.
List every device that must read and write your files, then check its ports, cables and file-system requirements before buying.
A NAS can make shared access and local recovery convenient, but Synology warns that RAID crashes and hard-drive failures can still cause data loss.
Plan a backup to a separately kept external drive or suitable cloud destination, and check that you can restore from it.
The separate destination needs its own storage and ongoing upkeep.
Seagate’s UK limited warranty excludes data loss and related recovery costs. Samsung says its T7 Shield liquid, dust and drop claims come from controlled tests and that resulting damage is not covered by its warranty.
Check the warranty for the exact model, but rely on separate copies rather than a warranty or ruggedness claim to protect your photos.
Seagate’s portable HDD range is relevant to a local photo-archive setup.
Samsung’s T7 Shield range is relevant to portable SSD storage for frequent file transfers.
Synology’s NAS guidance is relevant to households planning central storage and backups to another destination.
These portable SSDs suit frequent file transfers, while the portable HDDs offer local storage for a growing archive. Each is one possible backup destination, not a replacement for a second, separate copy; check your devices’ connections and read/write file-system needs before choosing.

Consider this portable SSD if you often move large photo or video files and want a 2 TB local copy. Its listed connection is USB Type-C 3.2 Gen 2; check your device’s port and whether its file system will let each intended device write to the drive.

This 1 TB portable SSD is an option for moving files between compatible devices. The title specifies USB 3.2 Gen 2; check your host and cable before relying on speed claims. Treat any handling-resistance claim as conditional, not as protection against losing files.

If photos start on a phone, this portable SSD’s magnetic set may suit a compatible iPhone 15 or 16 setup; check the attachment requirements for your case. The title lists USB 3.2 Gen 2 and speeds of up to 1,050 MB/s read and 1,000 MB/s write. The magnetic attachment does not provide wireless MagSafe charging.

The 5 TB portable HDD suits a growing local photo and home-file archive when frequent fast transfers are not your main concern. If you will write files from a Mac, check the required file system before filling the drive; keep another copy away from this one.

This 4 TB portable HDD can serve as an additional local archive for photos and documents. Its title lists USB 3.0; confirm the connector and file-system requirements of the computers that will use it, particularly if they run different operating systems.
Choose an HDD if the main task is a longer-term archive; choose an SSD if you frequently move or work with large files and have a suitable connection. Which? describes SSDs as faster but usually pricier. Neither drive should hold the only copy of irreplaceable photos.
No: a NAS can provide shared storage and local recovery, but it still needs a backup to another destination. Synology warns that RAID crashes and hard-drive failures can cause data loss, so plan how you would restore files from a separately kept drive or suitable cloud copy.
Yes, if you choose a file system both computers can write to. Apple identifies ExFAT as Windows-compatible and notes that a Mac may be able to read an NTFS drive without being able to write to it through Disk Utility. Copy existing files elsewhere before reformatting a drive.
It can count as an off-site backup when it holds a separate copy that you can restore. Check the restore process and protect the account: the National Cyber Security Centre notes that connected cloud backup locations can also be affected by ransomware incidents.
Do not assume it will. Seagate’s UK limited warranty excludes data loss and related recovery costs. Check the warranty for your exact model, and keep separate backups regardless of its hardware cover.
