What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Samsung T9 Portable SSD
Across three whitelisted lab reviews (StorageReview, TechRadar, PCWorld), the Samsung T9 is a fast, rugged USB 3.2 Gen 2x2 portable SSD that nears the ~2,000 MB/s interface ceiling, but is only a middle-of-the-pack 20Gbps performer, is overpriced at launch, and needs a rare USB 3.2 Gen 2x2 port to hit those speeds. (3 sourced reviews, 3 lab-tested.)
Praised: Fast Gen 2x2 performance, near the theoretical interface limits (roughly 1,900-2,000 MB/s reads); Rugged, premium build with a grippy textured/sculpted exterior; Strong sustained-write / large-file transfer behavior, especially on higher capacities.
Flagged: Expensive at launch versus the T7 and rival 2x2 drives; Only middle-of-the-pack among 20Gbps drives; SanDisk Extreme Pro V2 / Crucial X10 Pro faster; Requires a rare USB 3.2 Gen 2x2 port or speed is roughly halved.
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.
