Consumers echo the professional praise, highlighting the fast read speeds and the convenience of the capless design, while no major complaints appear in the available user-generated content. The drive is generally regarded as a dependable, lightweight option for routine file storage and transfer.
Retailer editors such as B&H Photo and Staples praise the drive's multi-proof construction and its advertised 400 MB/s read performance on USB-C 3.2 Gen 1, emphasizing fast and efficient data transfer for high-capacity needs. However, professional reviews are limited, leaving independent verification of real-world endurance and write performance scarce.
Everyday users consistently highlight the drive's high read speed, tiny form factor, and rugged, water- and shock-proof build as major positives for on-the-go use. The most common criticism revolves around the comparatively slow write speed and the absence of a protective cap.
