Updated 25 days ago · Based on the Amazon listing and published specifications, not hands-on testing.
A sensible carry drive for moving photos and files between a USB-C phone and a computer with full-size USB ports. Read speed is the headline figure, while write speed is listed without a unit, so copy performance onto the drive is unclear.

Overview
A swivel cover protects the two connectors on the SanDisk Ultra Dual Drive Go, a flash drive that carries both a USB-C plug and a USB-A plug. Files move between USB-C phones, tablets and Macs and USB-A computers, and the SanDisk Memory Zone app can back up a phone automatically.
Having both plug types on one stick removes the need for an adapter when files travel between a phone and a laptop. Phones must support On-The-Go connections, though, and automatic backup only works through SanDisk's app.
Who it's for
Suited to someone shuttling photos and documents between a USB-C phone or tablet and an older computer with full-size ports. Owners of phones lacking On-The-Go support should choose a different way to offload files.
Pros and cons
- Both USB-C and USB-A on one drive
- Swivel cover protects both connectors
- Keyring hole for carrying
- Automatic phone backup through SanDisk app
- Phone needs On-The-Go support to connect
- Backup requires installing SanDisk Memory Zone
- Write speed listed without a unit
Performance notes
Real transfer speed depends on the port and the host device, since the rated read speed needs a matching USB connection on the other end. Write speed is listed separately and without a unit, so how fast large files copy onto the drive cannot be judged from the listing.
