Capacity Note

Displayed capacity on your device may be slightly lower than the labeled capacity. This is normal — flash memory manufacturers use decimal (1GB = 1,000 MB) while operating systems use binary (1GB = 1,024 MB). For example, a 128GB drive typically shows 115–120GB on your computer. This does not affect the drive's real-world storage performance.

Frequently Asked Questions

Q: Is the SanDisk Ultra Dual Drive compatible with both Android phones and MacBooks?

A: Yes! The SanDisk Ultra Dual USB 3.2 Type-C flash drive features a USB Type-C connector for modern Android smartphones, tablets, and MacBooks, plus a USB Type-A connector for traditional laptops and desktop computers. This dual-connector design lets you transfer files between virtually any device without needing an adapter.

Q: What read speed can I expect from this SanDisk USB 3.2 flash drive?

A: The 64GB model delivers read speeds up to 300 MB/s, while the 128GB, 256GB, and 512GB models reach up to 400 MB/s. To achieve the best performance, make sure to use a USB 3.2 (or USB 3.0/3.1) port. Using an older USB 2.0 port will result in significantly lower transfer speeds.

Q: Why does the displayed storage capacity appear smaller than advertised?

A: This is a standard industry difference. Flash memory manufacturers calculate capacity using decimal math (1GB = 1,000 MB), while your operating system uses binary math (1GB = 1,024 MB). As a result, a 256GB drive will typically show around 230–240GB on your device. All capacity is genuine and the drive performs exactly as rated.

Q: Does this flash drive support file encryption?

A: Yes. The SanDisk Ultra Dual Drive supports 128-bit AES encryption, allowing you to password-protect sensitive files and folders directly on the drive for added security and peace of mind.
