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).
Crucial X10 Pro Portable SSD
Three whitelisted testers (Tom's Hardware, StorageReview, PCWorld) all lab-benchmarked the 2TB Crucial X10 Pro and recommend it: the fastest real-world 20Gbps USB SSD they tested, near Thunderbolt 3 in file transfers, with strong sustained writes. Caveats: it trails rival Gen 2x2 drives in synthetics and needs a rare USB 3.2 Gen 2x2 port. (3 sourced reviews, 3 lab-tested.)
Praised: Fastest / class-leading real-world 20Gbps USB performance, rivaling Thunderbolt 3 in file transfers; Excellent sustained write performance for large-file creative workloads; Compact, solid, IP55-rated metal shell at a reasonable price.
Flagged: Needs a rare USB 3.2 Gen 2x2 port; halves to 10Gbps on Thunderbolt/standard ports; Trails competing Gen 2x2 drives and Thunderbolt in synthetic/random benchmarks; Write speed collapses (to ~50MBps) once the SLC cache is fully exhausted.
