Choose a portable HDD for a growing local archive and routine backups, or a portable SSD if you regularly move large files and value faster transfers. Cloud storage provides an off-device route, but check its allowance and account access; for photos and files you cannot replace, keep a separate local copy as well, and disconnect the drive when it is not in use. Moving files off a full laptop frees space only if the copies you intend to keep have been checked before you delete the originals.
If photos, videos and documents are filling the laptop, decide which files need to remain on it and where a separate, recoverable copy will live. Archive capacity and access away from home may call for different storage routes.
If you frequently copy large photo or video folders or carry storage between locations, an SSD is worth considering for its faster transfers. The laptop port and cable still matter to the speed you can use.
If you would rather schedule backups than remember each copy, check the backup method, included folders and required drive format for your operating system before choosing storage.
Start with the files that need a second copy, then choose a storage route and capacity that fit how you will back them up and restore them.
| Priority | What to check | Your needs |
|---|---|---|
| Separate copies | Check where each copy lives and whether the backup can be opened. The National Cyber Security Centre advises disconnecting a backup device when it is not in use because malware can affect connected devices. | I want to clear space without leaving my photos only on one drive. I need to check the backup before deleting the laptop originals. |
| Drive capacity | Measure the folders to protect and allow for growth and backup history. For Time Machine, Apple Support recommends a disk with at least twice the Mac’s storage capacity. A computer may report a lower capacity than the manufacturer’s decimal figure, as Seagate explains. | My photo and video collection is growing, so the drive needs room for more than today’s files. |
| HDD or SSD | Match the drive to the routine: Which? describes HDDs as suited to long-term file backup and SSDs as faster but usually pricier. For an SSD, check the stated speed conditions rather than assuming its maximum applies to every laptop. | For occasional archive backups, I can focus on the space I need. If I copy large folders often, transfer speed matters more to my routine. |
| Cloud allowance | Count both the selected backup files and storage already used by the account. Google says its standard allowance is shared across Drive, Gmail and Photos, and reaching the limit can stop new photo or video backups. | I want an off-device copy, but I need to know which folders are backed up and whether the account has room for them. |
| Mac and Windows use | Check the backup workflow before formatting. Apple lists ExFAT for Windows-compatible volumes over 32 GB, but says Time Machine cannot back up to a Windows-formatted disk; reformatting that disk permanently removes its data. | If I share files between a Mac and Windows laptop, I need to distinguish ordinary file exchange from a dedicated Time Machine backup. |
| Ports and cables | Identify the laptop’s port specification and the cable required by the exact drive. Samsung says the T7 Shield’s stated maximum read and write speeds require a USB 3.2 Gen 2 host, compatible cable and UASP. | A USB-C connector alone does not tell me what transfer speed my laptop setup can deliver. |
| Recovery access | Check how drive encryption is unlocked and store recovery details separately. Microsoft warns that its support team cannot recreate a lost BitLocker recovery key. | I want private family files protected if a drive is lost, while still being able to restore them myself. |
Moving photos from the laptop to a USB drive can free space, but it leaves those photos on just one device. A drive left connected may also be affected by malware on the computer, as the National Cyber Security Centre warns.
Before deleting originals, check that the copy completed and open a sample of photos and documents. Keep another separate copy and disconnect the local backup drive when it is not in use.
Backup history needs space alongside current files. Cloud storage may also be shared with other services, while the capacity displayed by a computer can differ from a drive’s advertised decimal capacity.
Measure the folders you will protect and allow for growth. For Time Machine, Apple Support recommends a disk with at least twice the Mac’s storage capacity; for cloud storage, check existing account use as well.
The connector shape does not establish the host, cable and protocol conditions behind a speed figure. Samsung says the T7 Shield’s maximum figures require USB 3.2 Gen 2, a compatible cable and UASP.
Check the laptop port and the exact drive’s connection requirements before choosing an SSD for frequent large-file transfers.
Encryption can protect files on a lost drive, but losing the means to unlock it can also prevent a restore. Microsoft says its support team cannot recreate a lost BitLocker recovery key.
Keep the password or recovery key securely and separately from the laptop and drive, and check that the person responsible for restores can retrieve it.
Seagate’s One Touch range includes HDD and SSD options, so choose the type according to the backup routine rather than the brand name alone.
Western Digital’s My Passport USB-C line is relevant if portable HDD capacity and the connection type are central to your choice.
Samsung’s T7 Shield is a portable SSD option for repeated file transfers and carrying a local copy.
These portable HDD and SSD options address local photo and file storage. Choose one alongside a backup routine that keeps a separate copy; cloud storage is another route to consider for an off-device copy.

A 4 TB portable HDD to consider for a local photo and file archive. Measure the files you intend to back up and check the required format and backup method for your laptop before using it as a separate copy.

A 2 TB portable HDD for a local copy of photos and documents if that capacity fits your files and planned backup history. Check the intended Windows or Mac backup workflow before formatting or moving files.

A 4 TB portable SSD to consider when you frequently move large files as well as keep a local copy. Check the laptop port and cable before relying on a particular transfer speed, and confirm the format needed for your backup method.

A 1 TB portable SSD to consider for regular file transfers if that capacity covers your backup set. Samsung states maximum read and write speeds of 1,050 and 1,000 MB/s for this T7 Shield model; reaching them requires a USB 3.2 Gen 2 host, compatible cable and UASP. Keep another copy of files you cannot replace.

A 2 TB portable SSD for carrying a local photo and file copy. Check its connection, the format required by your laptop and how you will run repeatable backups before moving originals off the computer.
Measure the folders you will protect, then leave room for new files and backup history. For Time Machine, Apple Support recommends a disk with at least twice the Mac’s storage capacity and advises using it only for those backups where possible. The capacity your computer displays may be lower than the manufacturer’s decimal figure, as Seagate explains.
For ordinary file exchange, choose a format supported by the intended workflow; Apple lists ExFAT for Windows-compatible volumes over 32 GB. A Windows-formatted disk cannot serve directly as a Time Machine backup disk: Apple says it must be reformatted to a Mac file-system format, permanently removing existing data from that disk.
Choose an HDD for a mainly long-term local archive, or consider an SSD if you frequently copy large folders and faster transfers matter to you. Which? describes HDDs as suited to long-term backup and SSDs as faster but usually pricier. Either way, a drive holding the only remaining copy is not a backup.
Not automatically: making a remote copy does not itself remove local files. Check the provider’s file-management settings before changing what stays on the laptop. Also check the account allowance; Google says storage is shared across Drive, Gmail and Photos, and a full account can stop new photo or video backups.
Consider encryption, keep its password or recovery key somewhere secure and separate, and make sure you can retrieve it. Microsoft says BitLocker protects against offline access without the key, but its support team cannot recreate a lost recovery key. Disconnect a local backup drive when it is not in use, as the National Cyber Security Centre advises.
