LaCie Rugged SSD Pro
Only one whitelisted outlet (Tom's Hardware) has a hands-on, benchmarked review of this exact Thunderbolt 3 model. It rates the drive fast and cool-running with a rugged IP67 build, but flags a small SLC write cache, a steep price (about twice a typical 10 Gbps SSD), and the lack of AES hardware encryption found on the cheaper non-Pro Rugged SSD. (1 sourced review, 1 lab-tested.)
Praised: Competitive Thunderbolt 3 speed: ATTO ~2,450/2,130 MB/s read/write, peaking near 2.8/2.4 GB/s in iometer; Runs cool and avoids thermal throttling under sustained load, unlike the Samsung X5; Rugged IP67 build (3m drop, car-crush rated) with 5-year warranty plus Rescue data-recovery service.
Flagged: Small SLC write cache: sustained writes fall from ~2.1 GB/s to ~1.1 GB/s after roughly 25GB; Very expensive, about twice the cost of most 10 Gbps portable SSDs; Lacks 256-bit AES hardware encryption that the cheaper non-Pro Rugged SSD includes.
