waterproof usb drives

All product details list a USB‑A connector.

Access is controlled by an onboard numeric keypad requiring a PIN entered before connecting the drive; the described PIN length is 7–15 digits.

The drives automatically lock when unplugged or when USB power is removed. Some models can also be configured to auto‑lock after a predetermined timeout.

Listings mention dust resistance, wear resistance, crush resistance and rugged construction; one model is described as having an extruded aluminium sleeve.

Read speeds are listed around 169–170 MB/s. Write speeds vary by capacity and are reported roughly between 111 MB/s and 146 MB/s.

Compatibility listed includes Microsoft Windows, macOS/Mac, Linux, Android and Chrome, as well as thin/embedded platforms such as Thin Clients, Zero Clients, embedded systems, Citrix and VMware.

Several entries note a built‑in rechargeable battery or that a battery is required and non‑removable. Some listings specify a "1 Non‑Universal Lithium Ion" battery that is required and non‑removable.

If a user PIN is entered incorrectly 10 consecutive times, the user PIN is deleted (the admin PIN remains functional). If the admin PIN is entered incorrectly 10 consecutive times, the device deletes the PIN(s), the encryption key and stored data and reverts to factory default.
