Choose a portable HDD when you mainly need a separate, high-capacity copy that can stay in one secure place; choose a portable SSD for frequent large-file transfers or work while travelling. USB flash storage is more suitable for carrying selected files between devices, while cloud storage adds remote access but depends on available account capacity, internet access and continued service access.
You need a copy kept separately from a full laptop or phone, with room for photo libraries, documents and videos. Microsoft Support and the National Cyber Security Centre advise keeping important data in a separate backup location rather than relying only on the original device.
You regularly move large photo or video projects and need portable storage for travel. Samsung UK and SanDisk UK note that claimed SSD performance depends on the host device, cable and supported connection mode.
You transfer files between Windows PCs, Macs, USB-C phones or tablets and older USB-A computers. Connector type, power requirements and file-system formatting can matter as much as capacity.
Start by deciding whether you need a recoverable backup, a portable working drive, a simple transfer device or remote access to files. Then check compatibility before moving important data.
| Priority | What to check | Your needs |
|---|---|---|
| Separate backup copy | Choose a storage location separate from the original device; check whether your computer supports recurring backups; disconnect removable drives when they are not in use. | I want photos and documents to remain recoverable if a device is lost, fails or is infected. A local drive is more useful as a backup when it is stored separately and files can be restored. |
| Transfer speed and drive type | Compare the stated read and write figures; check the USB port, cable and protocol on the computer; treat maximum figures as conditional rather than guaranteed everyday results. | I regularly move large photo or video collections, or work directly from external storage. An HDD can suit stored backups, while an SSD is more relevant for frequent large transfers. |
| Device compatibility | Check the drive connector and supplied cable; decide on the file system before loading files; confirm any adapter, partition and power requirements for phone use. | I need files to move between Windows, macOS and possibly a phone or tablet. Reformatting can erase existing files, so I need another copy before changing a drive format. |
| Cloud capacity and access | Check how much account storage is available, whether it is shared with other services, and whether your connection is practical for initial uploads and restores. | I want photos available from signed-in devices and automatic backup options. Google One Help notes that Google account storage is shared across Gmail, Drive and Photos, so existing use affects available space. |
A drive or USB stick holding the only remaining copy of important files is not a resilient backup plan. A separate copy can help after device failure, loss, deletion or malware.
Keep at least one backup location separate from the original device. For irreplaceable files, consider a local copy alongside cloud backup and check that files can be restored.
Advertised peak speeds can require a specific USB generation, compatible host, suitable cable and transfer mode. A lower-capability port can limit transfer performance.
Check the exact computer port, drive interface and cable conditions before paying extra for a high-speed SSD.
Formatting may be needed for a mixed Windows and macOS setup, but Apple Support warns that erasing or reformatting a disk deletes its files.
Decide which devices need access before loading important files. If a format change is necessary, copy the full contents to another verified location first.
Phone storage workflows can depend on the connector, adapter, file system, partition layout and available power. Apple Support notes that external hard drives may need their own power source or a powered hub when used with iPhone.
Check the exact phone connector, intended app, adapter, drive power needs and supported file system before buying.
Some phone-and-drive combinations may require a compatible adapter or powered USB hub.

Joybuy product options for portable SSD and HDD storage when you need a separate local copy, frequent large-file transfers or a mixed-device setup.
No image available
A portable SSD for large local photo, video and computer-file libraries where compatible devices are used.
Stated 4 TB capacity; USB 3.2 Gen 2; up to 1,050 MB/s read and 1,000 MB/s write; USB-C-to-C and USB-C-to-A cables are listed. Maximum transfer speeds require a compatible USB 3.2 Gen 2 host and cable.
No image available
A portable option for large transfers when the drive is carried regularly and your host supports its interface.
Stated 1 TB capacity; USB 3.2 Gen 2; up to 1,050 MB/s read and 1,000 MB/s write; IP65 protection and up-to-3-metre drop resistance are listed. IP65 is for limited water exposure rather than submersion.
No image available
A mixed-device transfer option for compatible iPhone 15/16, PC and Mac workflows.
Stated 1 TB capacity; USB 3.2 Gen 2; up to 1,050 MB/s read and 1,000 MB/s write; USB-C-to-C and USB-A-to-USB-C cables are listed. Magnetic mounting is stated for iPhone 15/16-series use with the supplied case or ring.
No image available
A portable HDD to consider for regular computer-based local copies of photos and documents.
Stated 2 TB capacity; USB 3.2 Gen 1; USB bus power; 256-bit AES hardware encryption; USB-A-to-Micro-B cable included. It is stated as pre-formatted for Windows, and macOS use requires a downloadable driver.
No image available
A compact portable SSD for carrying photo, video and document libraries as a separate local copy.
Stated 2 TB capacity; up to 800 MB/s read speed; up-to-2-metre drop protection; rubber attachment hook; stated weight of 40 g. Check the supplied connector and cable ends for your intended computer or phone setup.
Yes, if the file system is suitable for both devices. Apple Support documents formatting an external disk for use with Windows and Mac, but warns that formatting erases all files already on the drive, so copy existing files elsewhere first.
It can work with a compatible connector or adapter and supported apps, but the drive must meet Apple’s file-system and single-partition requirements. Apple Support also notes that external hard drives may need their own power source or a powered hub.
No. USB-C describes the connector, not the full transfer capability of the computer, cable and drive combination. Samsung UK states that its T7 Shield maximum specification requires a USB 3.2 Gen 2-capable host and cable, plus UASP support.
Cloud storage can be one backup location for automatic photo backup and remote access, but it is not automatically a complete substitute for another independent copy. Google account capacity is shared across Photos, Drive and Gmail, while National Cyber Security Centre guidance supports using both online and storage-device backups for important data.
Treat it as electrical and electronic equipment rather than general waste, and erase accessible personal data first. GOV.UK guidance on WEEE regulations supports appropriate electrical-equipment recycling or locally available retailer take-back routes.
