SanDisk Ultra Backup 16 GB USB 2.0 Flash Drive

This SanDisk Ultra Backup drive provides 16 GB of portable storage with a retractable USB 2.0 connector. It features a hardware button that triggers an immediate backup of selected files without requiring additional software. Built-in password protection and 128-bit AES encryption secure sensitive personal or business data against unauthorised access.

Suitable for users needing simple.

The one-touch backup function suits professionals who want a quick, cable-free way to duplicate critical documents before travelling. Buyers who require faster transfer rates for large media libraries or who need a drive compatible with USB 3.0 or newer ports for optimal throughput should consider other options.

Retractable USB 2.0 connector with 16 GB capacity

The integrated retractable design protects the USB 2.0 interface when the drive is not in use, removing the need for a separate cap. Combined with 16 GB of space, this connector type determines the maximum transfer speed available for moving files between devices.

Questions about this item

How do I confirm the 16 GB drive is backing up correctly after I press the button?

The backup utility shows a progress bar and a completion message when the 16 GB transfer finishes; the LED on the retractable USB 2.0 connector flashes during the operation and stays solid once the 128-bit AES encrypted copy is verified.

What comes with the SDCZ40-016G and what must I supply myself?

The black drive measuring 0.25 x 0.75 x 2.75 inches includes the retractable USB 2.0 connector and pre-loaded backup software; you only need a Windows or Mac computer with a free USB port.

Which capacity should I choose if I only see the 16 GB version listed?

The product is offered in a single 16 GB capacity, so that is the version to select for password-protected, one-touch backup storage.
