Apricorn Aegis Secure Key 3 NXC 4GB-Black
Score: 80/100
iStorage datAshur BT 64GB
Score: 79/100Rankings

The Apricorn Aegis Secure Key 3 NXC 4 GB combines fast USB-C performance with 256-bit AES encryption and IP68 waterproofing in a compact aluminum case. Its tiny 4 GB capacity and need for periodic battery charging limit broader use. Best for security-critical tasks requiring a tiny, encrypted USB-C device.

The iStorage datAshur BT 64 GB provides FIPS-Level 3 hardware encryption with Bluetooth-based biometric unlocking via a smartphone app and IP57 ruggedness. Dependence on a paired phone and lack of a keypad can be limiting. It fits well for executives and field workers who value remote management.
