For a growing home archive that mainly stays in one place, a portable external hard drive is a straightforward route for a high-capacity local copy. Choose a portable SSD when frequent large transfers, compact carrying and a compatible faster USB connection matter more; use a USB flash drive for a limited file set, and consider NAS when several devices need shared, scheduled storage. A local drive works well alongside cloud storage when you keep backups current, test restoration and avoid leaving removable media permanently connected.
A straightforward local second copy can protect photos and documents that would be difficult or upsetting to lose after device failure, loss, theft, deletion or malware. Capacity planning and a repeatable backup-and-restore routine matter more here than maximum transfer speed. The National Cyber Security Centre advises keeping a backup in a separate safe location.
A portable SSD can suit frequent transfers and carrying, provided the computer has compatible faster USB hardware. Samsung notes that advertised transfer performance can vary with the system environment and UASP support.
NAS may suit homes where several devices need shared, scheduled or versioned storage. It requires more setup than a directly attached drive and should have a separate backup destination.
Start by measuring the files you want to protect, then check how the storage will connect and how often it will be used. A backup is only useful when you can restore the files you need.
| Priority | What to check | Your needs |
|---|---|---|
| Capacity | Measure the folders to be backed up; allow room for future files and retained versions. Check usable capacity and file-system compatibility for the exact drive. | I want space for my current photos, documents and videos without filling the backup destination immediately. |
| Compatibility and routine | Match the supplied cable and connector to USB-A, USB-C, Thunderbolt or any adapter required. Check operating-system, formatting and backup-software support. | I need storage that connects to the computers or devices I already use and fits a backup routine I can maintain. |
| Transfer speed and portability | Check the drive, cable, port and host support together. Compare stated read and write figures only for the same measurement basis and exact model. | Frequent large photo or video copies make faster transfers and an easy-to-carry drive more relevant than occasional home backups do. |
| Recovery resilience | Keep a copy in a separate location where practical. Disconnect removable media after backup, and periodically restore a non-critical file to confirm the process works. | I want a recent copy that remains useful if the main computer fails, is lost or is affected by malware. The National Cyber Security Centre advises against keeping backup devices permanently connected. |
A copy that is overwritten, deleted or affected alongside the original may not provide the recovery option you expect. Apple distinguishes syncing and storage from keeping additional copies.
For files that are difficult to replace, keep an independent local or cloud copy in addition to the working files, and check the restore process rather than assuming sync is a backup.
Ransomware or another computer problem can also affect a connected backup, reducing the protection it offers.
Once a backup is complete, safely disconnect the removable drive and store it securely. Reconnect it for the next scheduled or manual backup, then test restoration from time to time.
Transfer performance depends on the drive, cable, port and host support together. A drive may also need reformatting or an adapter for the devices you use.
Identify the ports on every intended device, check the supplied cable and any adapter requirement, and confirm operating-system and file-system support for the exact model.
An unsuitable connector or format can mean needing an adapter, replacement cable or a different drive.
A NAS can provide shared and versioned storage, but one kept in the same home and network may still be exposed to local loss or connected-device incidents.
If you choose NAS, plan a second backup destination from the outset instead of treating the NAS as the final backup layer.
A NAS setup can involve disks, network equipment, electricity and a separate external, remote or cloud backup destination.
Relevant for portable external HDDs where local backup capacity is the main decision. Western Digital lists WD Elements Portable variants from 1TB to 6TB with USB 3.2 Gen 1 or USB 3.0 connectivity.
Relevant for portable SSDs where compact carrying and faster large-file transfers on compatible hardware are important.
Relevant for a compact USB flash-drive route when moving selected files between USB Type-C and Type-A devices matters more than keeping a large whole-library backup.
Relevant for NAS-based household storage where scheduled tasks, versioning and shared access justify additional setup and hardware.
These Joybuy options cover portable SSD and external hard-drive routes for keeping a removable local copy of personal photos and documents.

A straightforward external-HDD route for keeping photos, videos and important documents in a local second copy.
Stated 2TB portable capacity, plug-and-play use and USB 3.2 Gen 1 connectivity. Check the supplied cable and connector, formatting for each intended computer, and whether 2TB leaves sufficient room for future files and retained versions.
Measure the folders you will actually protect, including photos, documents and videos, then allow for expected growth and historical versions if your backup tool keeps them. Do not rely only on headline capacity: Western Digital notes that actual user capacity can vary with the operating environment.
Choose a portable HDD when capacity for a growing archive is the main priority and transfers are occasional. Choose an SSD for frequent large batches and compatible faster connections; Samsung notes that its T7 Shield performance can vary with the system environment and UASP support.
An external drive can provide a separate local copy, but it does not automatically offer off-site access or protection from physical loss at the same location. The National Cyber Security Centre recognises both cloud storage and removable media as backup locations, so a cloud-plus-local approach can reduce dependence on one place when account access and local storage are protected.
No, if you want to reduce the chance that ransomware or a computer problem also reaches the removable backup. The National Cyber Security Centre advises that the device containing a backup should not be permanently connected; connect it for the backup, confirm completion, then disconnect and store it safely.
Periodically restore a non-critical photo or document to a different folder and confirm that it opens. The National Cyber Security Centre advises checking that you know how to restore files, while Windows File History and Apple Time Machine support restoration when configured.
