All-metal 2-in-1 drive for Type-C and Type-A

The SanDisk Ultra Dual Drive Luxe is a new 1TB USB flash drive with both a reversible USB Type-C connector and a traditional USB Type-A connector. Its all-metal swivel housing protects the connectors and includes a keyring hole for portability. It is built for users who move files between modern smartphones, tablets, Macs and older computers.

USB 3.2 Gen 1 caps transfer rates at 400MB/s

The drive uses the USB 3.2 Gen 1 interface, so the practical ceiling for sequential reads is 400MB/s. Write speeds will be lower and vary with the host device and file types. The dual-connector design does not increase bandwidth; it only removes the need for an adapter or cable when switching between Type-C and Type-A ports.

1TB capacity decides if it fits your library

The single specification that determines suitability is the 1TB capacity. Buyers who need more storage for large media libraries or system images cannot meet that need with this drive. Buyers who only transfer small documents or a few photos may find the capacity larger than necessary.

Questions about this item

Should I choose the 1TB model or a smaller capacity like 64GB?

The 1TB model stores far more photos, videos and documents, while the 64GB version suits lighter backup needs.

What does the 400MB/s read speed mean when I plug the drive into my laptop?

You can transfer large files such as 4K video clips in seconds rather than minutes, limited by your computer's USB port performance.

How does the USB 3.2 Gen 1 interface cap real-world transfer rates?

The interface supports up to 400MB/s reads, so actual throughput will not exceed that ceiling even on faster host ports.
