Overview

The SanDisk Ultra Dual Drive Go USB Type-C Flash Drive in 256GB is built for the reality of modern device ecosystems, where USB-C and USB-A ports coexist. Rather than carrying adapters or multiple drives, this single device gives you both connector types in a compact, pocket-friendly form factor. The USB-C end plugs directly into smartphones, tablets, and newer laptops, while the USB-A end ensures backward compatibility with older computers and peripherals. This makes it particularly useful for quickly offloading photos and videos from a phone or shuttling files between machines of different generations.

The swivel design is a thoughtful touch — rotating the drive body exposes one connector while shielding the other, eliminating the frustration of lost caps. A built-in keyring hole allows you to attach it to keys or a bag so the drive is always within reach. With 256GB of storage, this drive can hold substantial amounts of data, whether you are backing up a phone, carrying a library of documents, or transporting large media files between workstations. It is a straightforward, well-executed solution for cross-device file management.
