For a substantial file library that you need to carry to a replacement computer, consider a portable SSD; for a capacity-led local archive, consider an external hard drive. A USB stick suits a limited transfer, while cloud storage offers an off-device copy; an enclosure is relevant only if you need to read a removed drive. Whichever route you use, check capacity and compatibility, open files from the copy, then remove personal data before handing over the old device, as advised by Recycle Your Electricals and the Information Commissioner’s Office.
If photos, videos and documents need to move with you, measure the files you intend to keep and allow enough time to copy them. Which? describes external drives and cloud storage as transfer routes when moving to a new computer.
You need to preserve important files and confirm that the copy opens before removing personal information. Recycle Your Electricals advises backing up files before passing a device on; the Information Commissioner’s Office advises properly deleting personal data before disposal.
If you only need selected folders once, check their size and the ports on both devices before choosing a USB stick. Which? notes that USB sticks commonly use Type-A or Type-C connectors.
Decide whether you need a lasting backup or a one-off transfer, then check space, connections and how you will confirm that the files can be opened.
| Concern | What to check | Who this matters to |
|---|---|---|
| Archive capacity | Measure the folders you will keep and allow headroom; check usable drive capacity or the space available in your cloud account. | If I am keeping a large photo and document library, I need room for the files I cannot leave behind. Around 36% of consumers put archive capacity first. |
| Portable transfer | Check ports and the required cable on both devices; treat advertised transfer speeds as conditional on compatible hardware. | When I have a substantial library to move, I want a reusable drive that is practical to carry between computers. For around 29% of consumers, portable transfer is the primary need. |
| Verified backup and privacy | Open files from the destination before erasing the source; check file-system and encryption requirements where applicable. | Before I donate or recycle a device, I need to know my copy works and my personal data will not go with the old device. That comes first for around 21% of consumers. |
| Limited one-off transfer | Check that a USB stick has room for the selected files and that its connector fits the intended devices. | If I only need to take a few folders to another computer, I would rather choose for that task than for a full archive. Around 14% of consumers primarily need a limited one-off transfer. |
A drive enclosure or adapter serves a different situation: the storage has already been removed from the old computer. Check the removed drive’s interface and form factor, the enclosure’s connection and whether you have any encryption credentials needed to read the files. An enclosure is not a substitute for data-recovery help with a failed drive.
A drive or cloud account may fill before the intended copy is complete. Crucial notes that some labelled drive capacity is used after formatting; cloud-account space is separate from free space on the computer.
Measure the folders you intend to keep, leave headroom and check the space available at the destination.
The connector shape does not establish what the drive, cable and computer port can achieve together. Samsung’s stated maximum speeds for the T7 Shield require compatible USB 3.2 Gen 2 hardware and cables, with UASP enabled.
Check the port and cable specifications on the devices you will use, rather than choosing by a peak speed alone.
Apple says a Windows-formatted disk may need reformatting before use with Time Machine, permanently removing the files already on it.
Keep and open another copy of important files before reformatting a disk or setting up encryption that requires erasing it.
Finishing a transfer does not show that every file you need is present and accessible on the replacement device or service.
Open representative documents, photos and videos from the destination, confirm any account or recovery information you will need, and only then follow the old device’s erase guidance.
Its T7 Shield line is relevant when comparing compact portable SSDs with model-specific protection features.
Its X10 line is relevant when comparing portable SSD capacities for a larger file library.
A brand to consider when comparing external hard drives for a capacity-led local archive.
These portable SSDs and one external hard drive are choices for keeping a local copy or moving files to another device. Check the space you need and compatibility with both devices; you can also consider cloud storage separately if you need an off-device copy.

Consider this portable SSD when your selected files call for a 4 TB local drive. Its title specifies USB Type-C 3.2 Gen 2; check the file system, ports and cable needed for both computers.
No image available
This portable SSD is an option for a local copy when 2 TB accommodates the files you intend to keep. Its title specifies USB Type-C 3.2 Gen 2; confirm the file system and connections required by your devices.
No image available
Consider this 1TB portable SSD for files that fit within its capacity and need to travel between compatible devices. Its title specifies USB Type-C 3.2 Gen 2; check both devices’ connections and file-system requirements before relying on it for transfer.
No image available
This 1TB portable SSD is a local-transfer option if its connections suit your devices. Its title specifies USB 3.2 Gen 2 and claims up to 1,050MB/s read and 1,000MB/s write; check the host, cable and file system rather than assuming those speeds or cross-device compatibility.

Consider this 2TB external hard drive for a local archive rather than choosing solely for transfer speed. Confirm its connection and file system for your computers; if a Mac is involved, check the required setup before copying or reformatting files.
Yes: copy important files and check that you can open them before erasing the old device. Recycle Your Electricals advises backing up before passing a device on, and the Information Commissioner’s Office advises properly deleting personal information before disposal.
It can handle a limited selection if its usable capacity covers those files and its connector works with both devices. For a larger library or an ongoing backup, compare an external drive or cloud route instead; eject removable storage safely after copying.
For file transfer, check whether both computers can read and write the drive’s file system. Time Machine has a separate requirement: Apple says it cannot back up to a Windows-formatted disk, and reformatting that disk for Mac backup permanently removes its existing data.
It may be enough for selected folders, but compare their size with the space in your account. Microsoft Support states that a free Microsoft account includes 5 GB of OneDrive storage, with additional capacity available if needed.
Do not rely on a reset alone without following the instructions for your specific device and checking your backup first. Recycle Your Electricals notes that older Windows devices may need additional deletion steps, while the Information Commissioner’s Office advises properly removing personal information before disposal.
