Choose a USB-A drive if the group backs up files on USB-A computers, or a dual USB-A/USB-C drive if the same teaching pack regularly moves between both types of device. If the backup must contain personal information, assess whether an encrypted drive and a way to manage access are needed. Size the drive against the complete folder and any versions you intend to retain, and keep another copy elsewhere rather than relying on one flash drive.
Needs to copy presentations, worksheets and media using the group’s USB-A computers, then keep a controlled offline backup. The National Cyber Security Centre advises disconnecting backup storage when it is not in use.
Needs one teaching pack to move between USB-C and USB-A equipment without depending on an adapter. SanDisk documents both connectors on its Ultra Dual Drive Go.
Needs to consider how a portable backup containing attendee or learner information would be protected if lost. The Information Commissioner's Office identifies encryption as a way to protect personal information stored on USB media.
Check the ports on the devices that will use the backup, measure the files and retained versions, then decide how the group will carry, protect and recover the copy.
| Concern | What to check | Who this matters to |
|---|---|---|
| Device compatibility | List the ports on regular source and destination devices. Choose USB-A alone only if it fits them; otherwise check the connectors on a dual drive. | I move the same lesson pack between a USB-C laptop and a shared USB-A computer, so both plugs matter. Around 31% of consumers put mixed-device compatibility first. |
| Capacity and shared-PC use | Measure the full folder and the versions to retain, then compare that total with the space available on the drive. | Our teaching files stay on shared PCs, and I need a backup with room for the whole archive. A further roughly 31% of consumers prioritise straightforward, adequately sized shared-PC storage. |
| Carrying and transferring files | Check how the connectors are protected and whether speed figures apply to the chosen capacity; a read figure is not a write-speed figure. | I carry resource packs between venues and need a drive that is practical to handle before a session. About 23% of consumers place portability and transfer practicality first. |
| Personal information | Separate teaching materials from personal information where possible. If personal information must be stored, assess encryption, access recovery and secure storage. | Our backup includes attendee records, so I need to plan for a lost drive as well as a failed one. For around 15% of consumers, protecting personal information is the primary concern. |
A drive can be lost, fail or be affected while connected to a compromised computer. The National Cyber Security Centre warns that connected backup devices can be affected by viruses.
Keep another copy separately, disconnect the USB drive after backing up and occasionally check that essential files can be restored.
Recreating lost teaching materials can take time and disrupt sessions.
A USB-A plug will not fit a USB-C-only port directly. The interface label alone does not settle which physical connector the group needs.
Check the ports on every device used routinely for creating or retrieving teaching resources before choosing a single- or dual-connector drive.
SanDisk and Samsung specify read performance that depends on the model or capacity and use conditions. A quoted read speed does not establish how quickly files will be written during backup.
If the group regularly copies large media folders, check the selected capacity’s specifications for a stated write speed as well as its read speed.
USB media can be lost or stolen. The Information Commissioner's Office identifies encryption as effective protection for personal information stored on USB or backup media.
Keep personal information out of the resource backup where possible. If it must be included, assess an appropriate encryption method, control access and recovery information, and store the drive securely.
Kingston documents both a conventional USB-A route in the DataTraveler Exodia line and a separate encrypted route in the IronKey Keypad 200 line.
The Ultra Dual Drive Go is relevant when the same files need to move between USB-C and USB-A devices.
The BAR Plus line offers a compact metal-body option for a group using USB-A equipment.
These drives cover USB-A backups, moving files between USB-A and USB-C devices, and a keypad-encrypted option. Choose the connector and security approach that fit the group’s devices and files, then check capacity against the measured backup.

Consider this encrypted-drive route if the backup must include personal information and the group can manage PIN access and recovery.
The product name specifies 16GB and AES-256 encryption. Its FIPS 140-3 Level 3 status is described as pending, not completed; check whether 16GB accommodates the full backup.
No image available
Consider this standard-drive route if the group’s routine computers have the required port; check how any planned software-based file protection would work across those computers.
The named capacity is 128GB. Compare it with the complete teaching archive and versions to retain.
No image available
Consider this dual-drive route when lesson files move between USB-A and USB-C devices; check any required device or security-software compatibility before relying on those uses.
The product name specifies 128GB and a swivel metal housing. Measure the archive before settling on this capacity.

Consider this when the group moves teaching packs between USB-A and USB-C devices, provided its security approach also suits the files being carried.
The product name specifies 128GB, USB 3.2, a 360° swivel design and a metal body. Its 500MB/s figure is an advertised read-speed claim, not a measured backup write speed.
No image available
Consider this straightforward backup route if its connection and transfer performance suit the computers used by the group.
The product name specifies 64GB. Check the full archive size and retained versions before choosing it, particularly if teaching packs contain media files.
No: keep another recoverable copy separately. The National Cyber Security Centre advises secure storage and disconnecting a USB backup when it is not in use, because connected devices can also be affected by viruses.
Choose capacity after measuring the complete folder and any older versions the group will retain. Include presentations, images, audio and video, and leave room beyond the current set rather than judging by the number of documents.
Choose USB-A if every device regularly used for the backup has that port; choose a dual USB-A/USB-C drive if files routinely move between both port types. Check the physical connectors before buying, not just the USB version label.
Not every teaching file calls for the same protection: assess what the backup contains and the consequences of losing it. For personal information stored on USB media, the Information Commissioner's Office identifies encryption as effective protection; the group should also decide how authorised users will retain or recover access.
No. A hardware warranty does not recreate unique files on a lost or failed drive. Keep a separate copy and check periodically that the group can open and restore an essential teaching pack.
