Dual-connector flash drive

The SanDisk Ultra Dual Drive Go is a 256GB USB flash drive that combines a reversible USB Type-C connector with a traditional USB Type-A connector in a single swivel housing. It uses the USB 3.2 Gen 1 interface to deliver read speeds up to 400MB/s. The compact black design includes a keyring hole for portability. It is built for users who need to move files between modern Type-C devices and legacy Type-A computers.

Suits Type-C and Type-A workflows

This drive suits anyone who transfers photos, videos or documents between USB Type-C smartphones, tablets or Macs and older USB Type-A laptops or desktops. The SanDisk Memory Zone app can automatically back up phone content to free up local storage. It is not for buyers who need more than 256GB of capacity. It is also not for users who require a drive with only a single fixed connector type.

400MB/s read speed decides fit

The headline specification that determines suitability is the maximum read speed of 400MB/s over USB 3.2 Gen 1. This throughput governs how quickly large media libraries can be copied to a computer or offloaded from a phone. If your workflow demands sustained write performance or faster transfer rates, this model will not meet that requirement.

商品問答

Which ports must my phone or laptop have to use both connectors on the SanDisk Ultra Dual Drive Go SDDDC3-256G-G46?

Your device needs a USB Type-C port for the reversible connector and a USB Type-A port for the traditional connector to access the full 2-in-1 functionality.

Will the drive work at USB 3.2 Gen 1 speeds when I plug it into my older USB 3.1 Gen 1 laptop port?

Yes, the USB 3.2 Gen 1 specification is backward compatible with USB 3.1 Gen 1 ports, so you will see the same 150MB/s read performance on that laptop.

How can I confirm the drive is delivering the advertised 400MB/s read speed after I set it up?

Run a standard USB flash drive benchmark tool on a USB 3.2 Gen 1 Type-C or Type-A port and verify the sequential read result reaches up to 400MB/s.
