What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
SanDisk Extreme PRO Portable SSD V2
One whitelisted tester (StorageReview, Sept 2020) lab-benchmarked the 2TB Extreme Pro Portable SSD V2. Verdict: a fast, rugged (IP55), AES-256 hardware-encrypted USB 3.2 Gen 2x2 drive that nears its 2GB/s claim under heavy 4-thread load but falls short in lighter Blackmagic/single-thread tests. The Tom's Hardware source was dropped because fetch-clean returned only its page-1 spec sheet, so none of its quotes or measured performance/thermal values could be verified. (1 sourced review, 1 lab-tested.)
Praised: Strong sequential and 4K random write performance, near 2GB/s under 4-thread load; Rugged IP55 design plus 256-bit AES hardware encryption.
Flagged: Fell short of the quoted 2GB/s in lighter Blackmagic and single-thread tests (1.56GB/s read).
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.
