Dual-connector flash drive for Type-C and Type-A

The SanDisk Ultra Dual Drive Go combines a reversible USB Type-C connector with a traditional Type-A connector on a single swivel body. It offers 2TB of storage and read speeds up to 400MB/s. The drive is designed for users who move files between modern smartphones, tablets, Macs and legacy computers.

Check your device ports and app needs

Verify that your smartphone, tablet or laptop has a physical USB Type-C port that supports USB OTG or host functionality. The SanDisk Memory Zone app enables automatic backup of photos, videos, music, documents and contacts but requires a compatible Android device. Computers with only Type-A ports can still use the drive via the integrated Type-A connector.

Swivel metal shell with keyring hole

The black metal casing rotates to protect both connectors when not in use, removing the need for separate caps. At 0.34" x 0.48" x 1.75" and 0.01 lb it adds negligible bulk to a keychain or lanyard. The swivel mechanism keeps the chosen connector firmly extended during transfers.

Questions about this item

What comes in the box and do I need to buy a cable or adapter?

The drive has a built-in swivel that reveals both a USB Type-C and a traditional USB Type-A connector, so no separate cable or adapter is required.

Which capacity should I choose for my phone backups?

This model provides 2TB of storage, enough for large photo libraries, videos and documents from USB Type-C smartphones and tablets.

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

The 400MB/s figure is the maximum sequential read speed over the USB 3.2 Gen 1 interface; actual transfer rates depend on the host device and file types.
