Uncompromised Data Security
The OWC Guardian offers peace of mind with its advanced 256-bit AES OPAL hardware encryption. Your data is automatically encrypted as you save it and decrypted when accessed, ensuring protection without slowing down your device.

This performance ensures you spend less time waiting and more time creating, working, or sharing.

Designed for simplicity, the OWC Guardian features a smartphone-like colour touchscreen for intuitive navigation. Connect it to any USB-C equipped Mac, iPad Pro, or PC, and manage your files with ease. Its bus-powered design, complete with an included USB-C cable, eliminates the need for external power sources, making it perfect for travel or remote work. Whether you’re a Mac or PC user, the Guardian adapts effortlessly, with quick reformatting options for Windows and compatibility with OWC MacDrive (sold separately) for cross-platform use.
Customisable Access for Maximum Control
