Frequently Asked Questions

Will this work with my Android phone?

It works with Android devices that have a USB Type-C port and support USB On-The-Go (OTG). SanDisk lists both as requirements; if your phone predates USB-C or lacks OTG, the drive will not mount.

How fast is the SanDisk Ultra Dual Drive?

SanDisk rates it at up to 150MB/s read speeds over USB 3.1 Gen 1, based on internal testing. You need a USB 3.1 Gen 1 or USB 3.0 host port to reach that; actual speed varies by device.

Does it need an adapter to plug into a laptop?

No. The drive is dual-ended: retract one side for the reversible USB Type-C connector, the other for a standard USB-A connector, so it plugs directly into most phones and computers.

How much can 256GB actually hold?

256GB is enough for a large phone photo library plus several hours of 4K video offloads. Capacity is the main reason to pick this over the 64GB and 128GB versions of the same drive.

Is there software included, and what is the warranty?

SanDisk offers the free Memory Zone app for Android through Google Play to manage device memory and move content to the drive. Check the current product listing for warranty terms in your region.
