Choose a drive whose connector works with both the recorder and the computer used to transfer files, or confirm that a suitable adapter is included. Match capacity to the recording files you expect to retain. If recordings contain personal data and the drive will be carried, assess the risk of loss or unauthorised access before choosing between conventional storage and an encrypted drive; either way, keep a separate backup.
If a drive moves between locations, loss or unauthorised access can matter as much as storage capacity. The Information Commissioner’s Office advises security measures appropriate to the risk when personal data is involved; a PIN-protected encrypted drive may be appropriate, alongside a separate backup and a plan for managing access.
For repeated transfers from a recorder to a computer, check the ports on both devices before comparing capacity and published speeds. USB-A and USB-C versions serve different connections, while an advertised read speed does not establish how quickly every recording will be written to the drive.
A small collection of recordings may call for a straightforward removable drive, provided it fits the transfer devices and the security approach suits the files. Copy recordings to the approved primary storage rather than leaving the flash drive as the only copy.
Check the recording’s confidentiality and the devices’ ports before comparing capacity or speed. A faster conventional drive is still a conventional drive: published transfer figures do not add access control.
| Concern | What to check | Who this matters to |
|---|---|---|
| Protecting recordings | Check whether files contain personal data and what security process applies. If considering a PIN-protected drive, plan credential management and a separate backup. | If I carry identifiable interviews, I need to limit access if the drive is lost without risking my only copy through a lockout. Around 50% of consumers put protection of the recordings first. |
| Connecting both devices | Inspect the recorder and computer ports; if an adapter is needed, confirm that the exact model includes one suitable for data transfer. | Moving files between USB-A and USB-C equipment is difficult if the drive cannot connect when I need it. For around 30% of consumers, a workable connection is the primary need. |
| Capacity and transfers | Use the recorder’s file sizes and expected retention period to plan free space. Check speed claims for the exact capacity and the host conditions. | When I retain several sessions or copy batches often, I need enough room between transfers and realistic expectations about copy times. That is the main concern for around 20% of consumers. |
A durable casing and a high stated transfer speed do not provide encryption or access control. The Information Commissioner’s Office identifies encryption as a protection to consider for personal data stored on USB media.
For identifiable interviews, assess the risk of loss and check whether an encrypted drive or another approved encrypted-storage process is appropriate.
Recording-file size depends on the recorder’s format, and not every labelled gigabyte is available for files.
Use files from your recorder to estimate space per interview, then allow room for additional sessions and delays before the next transfer.
Samsung states that actual speed varies with the host device and conditions. A maximum sequential-read figure also does not establish the write speed of a recording transfer.
Check the connector and ports on both devices, and read speed specifications for the particular capacity rather than assuming the same result on every computer.
Kingston states that repeated incorrect administrator PIN attempts can crypto-erase an IronKey Keypad 200 drive. Protection against unauthorised access must therefore be paired with a way to retain access to the recordings.
Decide who manages administrator credentials, test the approved recovery process and keep a separate protected backup before taking the drive into the field.
Kingston offers both conventional DataTraveler Exodia USB-A storage and PIN-authenticated IronKey Keypad 200 drives, which come in USB-A and USB-C variants.
Samsung BAR Plus is a conventional, metal-bodied USB-A range available in capacities from 64GB to 512GB.
SanDisk Ultra Luxe is a metal-cased USB-A range with capacities from 32GB to 1TB.
iStorage datAshur PRO+C is a USB-C, PIN-protected hardware-encrypted range supplied with a USB-C-to-USB-A adapter.
These drives cover conventional removable storage, dual-connector options and keypad-protected storage for interview files. Compare the exact connector, protection method and capacity against your recorder, computer and handling process.

Consider this model if transfers involve both USB-A and USB-C ports and fingerprint access fits your security process.
The product name specifies dual interfaces, fingerprint encryption and a zinc-alloy body. Its stated maximums of 550MB/s read and 500MB/s write are product claims, not guaranteed transfer times; confirm how fingerprint access works with your devices and keep a separate backup.

This keypad-protected option is relevant when a USB-A transfer workflow calls for controlled access to portable interview files.
Kingston specifies XTS-AES 256-bit hardware encryption for the Keypad 200 range. Check whether 16GB accommodates your recordings; Kingston also warns that repeated incorrect administrator PIN attempts can crypto-erase the drive, so plan PIN management and a separate backup. If certification is a requirement, confirm the status of this exact variant before purchase.

Consider this dual-connector drive when recording transfers cross devices with different ports.
The product name specifies USB-C and a swivel metal housing. If you intend to protect files with Lexar’s software-based encryption, confirm that the software works on every computer that needs to open them; check the exact connectors against your recorder and computer.

This 32GB Keypad 200 is another option for a workflow requiring PIN-controlled access to portable recordings.
Kingston specifies XTS-AES 256-bit hardware encryption for the range. Confirm the connector on this exact variant before buying; manage administrator PINs and maintain a separate backup because repeated incorrect administrator PIN attempts can crypto-erase a Keypad 200 drive. Confirm variant-specific certification status if it matters to your organisation.

This conventional removable drive suits a recording-transfer process where its connector and the chosen file-protection method meet your needs.
It has a stated 128GB capacity. If you plan to use the described password-protected folder, confirm that the required software works on the computers used to store and retrieve interviews; check the recorder and computer ports as well.
Not automatically in every case. Where recordings contain personal data, the Information Commissioner’s Office says security measures under UK GDPR should be appropriate to the circumstances and risk, with encryption considered where appropriate. Assess what the recordings contain, where the drive travels and who can access it, alongside your organisation’s policy.
Choose a connector that works with the recorder and the computer used for transfer. If they have different ports, check the exact drive’s connectors or whether it includes a suitable data-capable adapter; iStorage specifies a USB-C-to-USB-A adapter for datAshur PRO+C.
Base capacity on the recorder’s actual file sizes, expected interview lengths and how long files remain on the drive, then leave free space for extra sessions. Labelled capacity is not wholly available for files, so a capacity choice cannot be made from interview count alone.
Do not rely on the flash drive as the only copy. The Information Commissioner’s Office advises measures that support restoring access after an incident, including an appropriate backup process. Copy recordings to approved primary storage and check that the copies open before deleting the originals or reformatting the drive.
