While no independent tech-site reviews were found, manufacturer and retailer descriptions quoted by industry editors stress the datAshur PRO's military-grade FIPS 140-2 Level 3 encryption, rugged IP57 construction, and the convenience of software-free, keypad-controlled security that works across a wide range of operating systems.
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.
