Score: 44/100Rankings
The Ultra Fit 32 GB drive is an ultra-compact, plug-and-stay flash drive with fast read performance and built-in encryption, ideal for static installations like laptops or car audio. Its plastic build and occasional heat limit suitability for heavy-use scenarios.
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.
