What reviewers say

Sourced tester consensus for each — the "what people who used it think" layer, not just specs.

WD My Passport SSD (2022)

Two whitelisted labs benchmarked the WD My Passport SSD NVMe (1,050/1,000 MB/s, USB 3.2 Gen 2, DRAM-less Blue SN550E): Tom's Hardware (Feb 2021) and StorageReview (Sep 2020). Both call it slim, secure and fast in real-world use but note it falls ~200 MB/s short of its rated speeds and, being DRAM-less, lags DRAM-based rivals like the Crucial X8 in file-copy/moderate-dataset tests. Tom's found a small 12GB SLC cache that drops sustained writes to ~710 MBps once saturated, though the drive stays cool (45C surface). (2 sourced reviews, 2 lab-tested.)

Praised: Slim, light, pocketable design with AES-256 hardware encryption and 5-year warranty; Fast large-file read-back and solid real-world portable-SSD performance; Runs cool under sustained load (45C surface).

Flagged: DRAM-less design; falls behind DRAM-based rivals (Crucial X8) and lags in file-copy tests; Fell short of WD's rated 1,050/1,000 MB/s in real benchmarks (~200 MB/s under); Small SLC cache (12GB) drops sustained write to ~710 MBps once saturated.

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.
