Choose a portable SSD when you regularly move large files, need quick access between locations or work from the drive; choose a portable or desktop HDD when local backup capacity matters more than transfer speed and resistance to knocks. An automatic-backup device or NAS can suit several devices needing routine copies, but requires network setup and ongoing management. Microsoft, Apple and the UK National Cyber Security Centre also stress that a drive needs a configured backup routine and a separate recoverable copy.
A portable SSD can suit fast transfers and portable access between a laptop, desktop and compatible mobile devices. Check the port and cable requirements on every device first. Samsung UK, Crucial UK, Which? and PCMag UK identify interface support and transfer performance as important conditions.
A desktop HDD or another always-available backup destination can suit photos, documents and videos when you set up File History or Time Machine and retain another separate copy. Microsoft Support, Apple Support and Western Digital describe these routes for regular backups.
An automatic-backup device or NAS is more relevant when phone photos, computer backups and shared storage need a regular routine. Allow for router-connected equipment and initial setup; Synology UK describes this type of home-storage route.
Start with the files you need to protect, then check the connection path and backup routine before choosing capacity or headline transfer speeds.
| Priority | What to check | Your needs |
|---|---|---|
| Transfer speed and capacity | Compare the drive capacity with current files, future growth and versioned backups. Check the host port, cable and USB standard before relying on stated read and write figures. | I need enough room for a growing media library, while large imports, copies or editing should not be held back by an incompatible connection. |
| Portable handling | For a drive carried in a bag, compare SSD and HDD construction. Check any stated drop or ingress rating and its test conditions rather than assuming all portable drives offer the same protection. | I want a local copy I can carry between locations without making routine knocks an afterthought. |
| Device compatibility | Confirm the exact USB-A or USB-C connection, adapter needs, filesystem, partition layout and power requirement. For phone use, check the device model and storage or OTG support. | I need the drive to mount and transfer files on my own phone, tablet, Mac or Windows PC before it becomes part of my backup routine. |
| Backup routine | Check whether File History, Time Machine or another backup tool can use the destination. Confirm important folders are included, leave room for backup history and test a sample restore. | I want regular copies rather than occasional manual transfers, plus an independent copy for files that would be difficult to replace. |
Headline sequential speeds are conditional. Samsung UK says T7 Shield maximum speeds require USB 3.2 Gen 2, UASP and a compatible cable and host; Crucial UK similarly specifies USB-C to USB-C and a USB 3.2 Gen 2 host for its highest stated speeds.
Identify the ports on every device you will use, check whether USB-A, USB-C, USB4 or Thunderbolt compatibility is needed, and confirm the cable supplied with the drive.
USB-C is a connector rather than a guarantee of storage compatibility or power delivery. Apple Support specifies a compatible connector or adapter, one data partition and a supported filesystem for iPhone external storage; external HDDs can require external power.
Check the phone model, storage or OTG support where applicable, filesystem and partition requirements, and whether the drive is bus-powered or needs additional power.
A compatible adapter or powered USB hub may be needed.
Manual copying can miss folders, new files and earlier versions. Microsoft File History and Apple Time Machine can automate versioned backups, while the UK National Cyber Security Centre warns that connected backups are not ransomware-resistant by default.
Configure scheduled backup software, confirm photo libraries and document folders are included, restore-test a sample of files and keep another independent copy of important data.
Which? notes that HDDs are typically slower than SSDs and have moving parts that are more susceptible to damage from bumps and knocks. That can be a reasonable trade-off for a stationary archive, but is less suitable for frequent carrying and active editing.
Use a desktop or portable HDD for capacity-led local backup when it will be handled carefully; consider a portable SSD when quick transfers and resistance to routine knocks matter more.

A portable option for a large photo, video and document collection that also needs faster copying between compatible computers.
The listing states 4TB capacity, USB 3.2 Gen 2, up to 1,050MB/s read and 1,000MB/s write, with USB-C-to-C and USB-C-to-A cables included.
Actual speeds depend on the host port and cable path. Check formatting and partition compatibility before using it as the only copy of important files; the listing does not describe water or dust resistance.

This compact SSD suits carrying a sizeable local copy and moving files between compatible computers.
The listing states 2TB capacity, USB 3.2 Gen 2, up to 1,050MB/s read and 1,000MB/s write, plus USB-C-to-C and USB-C-to-A cables.
Slower USB ports reduce achievable speed. The listing says it is not water- or dust-proof, so check that its handling limits and filesystem suit your workflow.
No image available
A portable SSD for travel-heavy photo and video transfers where stated dust, water and drop protection are relevant.
The listing states 1TB capacity, USB Type-C, USB 3.2 Gen 2, up to 1,050MB/s read and 1,000MB/s write, IP65 resistance and up to 3m drop resistance.
IP65 protection is stated for temporary water exposure and not submersion. Compare 1TB with the source data and planned backup history, and check that the host and cable can support the required USB mode.

A compact transfer and local-storage option for files and media shared between compatible computers.
The listing states 1TB capacity, USB 3.2 Gen 2, up to 1,050MB/s read and 1,000MB/s write, with USB-C-to-C and USB-C-to-A cables included.
Check whether 1TB leaves enough room for a growing archive and versioned backups. The listing states that the drive is not water- or dust-proof, and phone use depends on formatting, partitioning and device support.
Yes, if the iPhone, connector or adapter, drive power requirement, partition layout and filesystem are compatible. Apple Support lists APFS, encrypted APFS, Mac OS Extended, exFAT, FAT32 and FAT among supported formats, requires one data partition, and notes that external HDDs often need their own power source.
It can be a practical starting format for a cross-device transfer drive because Apple Support lists exFAT for iPhone external storage and Crucial UK ships the X9 in exFAT. Check every intended device and backup app before reformatting, as formatting erases existing data.
Apple Support recommends a storage device with at least twice the storage capacity of the Mac. A dedicated Time Machine disk leaves room for backup history, although older backups are deleted when the disk becomes full.
Yes. Microsoft Support says File History can make regular copies to an external drive or network location and restore earlier versions. Check that folders holding important files are included in the configured libraries.
No. An external drive can provide a useful local copy, but the UK National Cyber Security Centre says backups are not ransomware-resistant by default. Keep a separate recoverable copy and periodically test that important files can be restored.
