Professional reviewers commend the Vx450 as a high-performance portable SSD that brings near-internal SSD speeds to the USB 3.0 world, while noting speed dependence on the host's USB controller.

“Compact size makes it perfect for travel”




Professional reviewers praise the SSD-PUT for its miniaturization, solid-state performance in a thumb-drive form factor, and rugged build, but note its modest PCMark score and the need for a firmware update, positioning it as a portable alternative rather than a high-end external SSD.
Everyday users love the tiny size, speed for file transfers, and durability, especially for gaming consoles and travel, while recurring frustrations focus on the required firmware update and the easily misplaced USB-C adapter.
