A 512 GB flash drive with reversible USB-C and USB-A connectors, up to 400 MB/s read speed and a swivel design with keyring hole
USB Specification Ultra Dual
Struck-through versions exist but are not stocked here.
The SanDisk Ultra Dual Drive Go provides 512GB of storage in a compact swivel housing. It combines a reversible USB Type-C connector with a traditional USB Type-A connector. The drive reads data at up to 400MB/s over a USB 3.2 Gen 1 interface. It is formatted for immediate use across phones, tablets, laptops and desktops.
This drive suits anyone who transfers photos, videos or documents between modern smartphones, tablets or Macs and older USB-A computers. The integrated keyring hole makes it convenient to carry daily. Buyers who require only a single connector type or who need higher sustained write performance for large video projects should consider other options.
The 512GB capacity determines how many photos, videos and documents you can store before offloading. The 400MB/s read speed governs how quickly those files copy to a computer for editing or backup. Match both figures to your typical file volumes and transfer patience to decide if this is the right part.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Real-world transfer rates depend on the host controller, file sizes and drive formatting; the 400MB/s figure is the maximum sequential read under ideal conditions.
Both connectors operate at USB 3.2 Gen 1 speeds, so each port is limited to the same 400MB/s read ceiling the drive specifies.
The drive measures 0.34" x 0.48" x 1.75" and weighs 0.01 lb, with a built-in keyring hole on the swivel cap.
