SanDisk Ultra Dual Drive 128GB
Score: 39/100Rankings
The Ultra Dual Drive 128 GB offers a sturdy metal body with both USB-A and USB-C connectors, delivering fast reads and a convenient keyring loop. Lack of native encryption and modest write speeds make it better suited for occasional transfers than heavy-write tasks.
The Ultra 128 GB USB 3.0 flash drive offers solid read performance and built-in encryption in a compact retractable form factor, targeting everyday users. Write speeds lag behind the advertised maximum, and the slider mechanism may collect dirt over time.
