Choose a portable SSD when you regularly move large project folders and need quick transfers in a device suited to travel. A high-performance USB flash drive is a compact alternative for transfers that fit its capacity, while a portable hard drive suits capacity-led use when protected carrying is practical; cloud transfer works when the connection, service limits and workplace rules fit the files.
People carrying video, design, photo, software or other large work folders between computers and looking to reduce copying time. A portable SSD is worth assessing when both machines support the required USB connection; Samsung UK documents USB 3.2 Gen 2 specifications for its T7 range.
People moving moderate amounts of data often who value a small drive that plugs in directly. Check that both computers have the selected connector, or that a suitable adapter is allowed; Kingston's cited DataTraveler Max version uses Type-C.
People transporting a substantial archive or media library who prioritise capacity and can protect a mechanical drive while travelling. Seagate UK positions its One Touch portable-drive range for high-capacity storage and USB 3.0 connectivity.
Start with the largest transfer you expect to carry, then check the ports, cables and protection requirements at both locations.
| Priority | What to check | Your needs |
|---|---|---|
| Transfer time | Compare read and write figures for the exact model. Check USB version, cable capability and UASP support where required for stated maximum speeds. | I need large project folders copied without a long wait. A portable SSD or high-performance flash drive may suit this route when both computers support the connection. |
| Usable space | Choose capacity for the largest regular transfer with headroom. Check cloud storage allowance and any per-file limit separately. | I want room for the files I carry now and temporary working copies. Headline flash capacity is not all available for files after formatting and device functions. |
| Compatibility | Match Type-C or Type-A connections to both computers. Confirm cable, operating-system and file-system compatibility before a large transfer. | My home and work computers need to use the same drive without an unexpected connector or formatting problem. |
| Travel protection | Check the stated encryption or password options and the conditions behind any IP or drop-test claim. Carry small drives securely. | I carry personal or confidential files and want to reduce the risk if the device is lost, stolen or knocked in transit. |
| Cloud practicality | Check the approved service, account limits, largest individual file and actual upload conditions at both addresses. Microsoft states that OneDrive web uploads can be up to 250GB per file. | I want access without carrying a drive, but only if upload time and workplace approval make repeated transfers practical. |
A USB 3.2 Gen 2 SSD will not automatically reach its published maximum rate on an older port or an unsuitable cable. Samsung states that its T7 and T7 Shield maximum figures require compatible USB 3.2 Gen 2 hardware, cable support and UASP.
Check the ports on both computers and the cable specification before paying extra for a faster drive.
Cloud transfer can be limited by account capacity, per-file limits, workplace policy and the upload connection at each location. Ofcom's January 2026 UK snapshot reported broad full-fibre availability, but this does not establish the speed at a particular address.
Confirm the approved service, available storage, largest file and upload conditions at home and work before relying on cloud-only transfer.
A portable device can be lost or stolen while travelling. The Information Commissioner's Office says encryption of personal information on USB and other removable media provides effective protection against unauthorised or unlawful processing.
Use employer-approved encryption and access controls for confidential files, and keep passwords or recovery information separate from the device.
Usable capacity is lower than the figure on the label, and the file system can affect whether an individual very large file can be handled.
Leave capacity headroom and check the file system and cross-platform compatibility before moving the only copy of an important file.
Relevant for repeated large-file transfers using a portable SSD. Samsung UK publishes exact-model connection, cable, speed and travel-protection information for the T7 and T7 Shield ranges.
Relevant when a direct-plug-in, high-performance Type-C flash drive is preferable to carrying a cable-connected SSD.
Relevant for people carrying archives, media libraries or other larger collections where capacity is more important than SSD-class transfer speed.

A 1TB portable SSD route for regular project-folder transfers and commuting.
Stated USB 3.2 Gen 2 connection and up to 1,050MB/s read and 1,000MB/s write figures; IP65 and a 3-metre drop claim are listed.
Check USB 3.2 Gen 2, cable and UASP support before expecting maximum speeds. IP65 is for temporary water exposure, not submersion; confirm file-system handling before work transfers.
No image available
A higher-capacity option for recurring transfer sets or large media libraries.
Stated 4TB capacity, USB 3.2 Gen 2, claimed up to 1,050MB/s read and 1,000MB/s write, plus Type-C-to-C and Type-C-to-A cables.
Maximum speed depends on a compatible host and cable. The stated model is not IP-rated for water resistance, so protect it from liquids during travel.
No image available
A 2TB option for carrying large work folders between computers with different USB socket types.
Stated USB 3.2 Gen 2 connection, up to 1,050MB/s read and 1,000MB/s write, and included Type-C-to-C and Type-C-to-A cables.
Maximum speed is conditional on a compatible USB 3.2 Gen 2 connection. The stated model is not waterproof or dustproof, so use protected transport.
No image available
A compact SSD option for frequent large-file transfers without carrying a mechanical drive.
Stated 1TB capacity, USB 3.2 Gen 2, claimed up to 1,050MB/s read and 1,000MB/s write, with optional AES-256 hardware encryption.
Check both computers' USB support before relying on the top speed. The stated model is not water- or dust-resistant; verify its file system and approved encryption setup for sensitive files.

A 1TB portable SSD option for transfers between Type-C and USB-A computers.
Stated USB 3.2 Gen 2 connection, up to 1,050MB/s read and 1,000MB/s write, with USB-C-to-C and USB-A-to-C cables listed in the package.
Confirm the exact security implementation if carrying sensitive files. Check host USB capability, cable support and the required file system before copying very large files.
Choose capacity for your largest normal transfer set, with room for files you need to keep temporarily on the drive. Do not assume all labelled capacity is available: Kingston states that formatting and other functions use part of flash storage. For cloud transfer, check both account storage and the per-file limit; Microsoft states that OneDrive web uploads can be up to 250GB per file.
No. Samsung states that the maximum read and write figures for its T7 and T7 Shield require a host device and cable supporting USB 3.2 Gen 2, with UASP enabled. Check both computers' ports and the included or replacement cable before treating an advertised speed as achievable.
It can when both locations have reliable internet, the service is approved for the files, and its storage and per-file limits fit the job. It is less dependable for time-critical repeated transfers when upload capacity is weak or variable; Ofcom's UK availability data does not guarantee the speed at either address.
For organisations handling personal information, Information Commissioner's Office guidance says encryption of data on USB and other removable media provides effective protection against unauthorised or unlawful processing, especially after loss or theft. Follow your employer's approved encryption and file-transfer policy, and keep credentials separate from the device.
Yes. Verify the drive's current file system and compatibility with both computers before transfer, particularly for individual multi-gigabyte files. Microsoft documentation describes a FAT32 issue involving files of 4,294,967,295 bytes, so removable drives should not be assumed to handle every file in the same way.
