Overview

The SanDisk Cruzer Ultra USB 3.0 Flash Drive in this 10-pack configuration is aimed at buyers who need multiple reliable drives on hand — whether for distributing files across a team, equipping a classroom, or simply keeping backups in several locations. Each 16GB drive supports USB 3.0 read speeds up to 100MB/s, a significant step up from USB 2.0, making routine file transfers noticeably faster. The drives remain fully backward compatible with USB 2.0 ports for use with older machines.

A standout feature is the bundled SanDisk SecureAccess software, which creates a password-protected partition secured with 128-bit AES encryption. This lets you keep confidential documents locked down while still using the remaining drive space for everyday sharing. The compact, retractable USB connector eliminates the need for a cap, reducing the chance of losing parts. At 16GB per drive, these are best suited for documents, presentations, and moderate-sized file transfers rather than large video or archive storage.

Frequently Asked Questions

What transfer speeds can I expect from the Cruzer Ultra USB 3.0?

The drive supports read speeds up to 100MB/s when connected to a USB 3.0 port. Write speeds will be slower, and actual performance varies with file sizes and system configuration.

Are these drives backward compatible with USB 2.0 ports?

Yes, the Cruzer Ultra works in USB 2.0 ports, but transfer speeds will be limited to USB 2.0 rates rather than the full USB 3.0 speed.

What does the included SanDisk SecureAccess software do?

SecureAccess lets you create a password-protected, 128-bit AES encrypted vault on the drive. You can store sensitive files in the vault while keeping the rest of the drive's storage open for general use.

Is each drive in the 10-pack individually packaged?

The drives come together as a bulk 10-pack, making them ideal for IT departments, classrooms, or offices that need to distribute multiple drives at once.
