Versatile 64GB dual-connector drive

The SanDisk Ultra Dual Drive SDDDC2-064G-G46 provides 64GB of portable storage with both a reversible USB Type-C connector and a traditional USB Type-A connector. It is built for users who move files between modern smartphones, tablets, and laptops as well as older computers that only offer Type-A ports. The retractable design protects both interfaces when the drive is not in use.

Check your device ports and OS support

Verify that your target devices physically accept either a USB Type-C or USB Type-A plug before ordering. Confirm that the host operating system supports USB mass storage so the drive appears without extra drivers. The connector is USB 3.1 Gen 1, so a Type-C port that only carries power or video will not provide data access.

Sustained throughput on large transfers

The drive is rated for read speeds up to 150MB/s over USB 3.1 Gen 1, though actual sustained rates depend on the host controller, file sizes, and thermal conditions. During extended write sessions the flash memory and controller temperature can rise, which may reduce throughput compared with short benchmark bursts. The small metal chassis offers limited heat dissipation for continuous heavy workloads.

Questions about this item

Does the box include a cap or cable for the USB-C and USB-A connectors?

The drive has a retractable design that covers both the reversible USB-C and traditional USB-A connectors, so no separate cap or cable is needed.

Is the 64GB version the only capacity available in this Ultra Dual series?

This specific model is the 64GB capacity; other capacities are separate model numbers not covered by this listing.

What does the 150MB/s read speed mean when copying photos to a laptop?

The 150MB/s figure is the maximum read speed over USB 3.1 Gen 1; actual transfer rates depend on the host device and file sizes.
