What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Samsung PRO Plus Full-Size SD 256GB (2023)
Only one whitelisted tester (StorageReview) benchmarked this exact 2023 full-size 256GB model; no Tom's Hardware, TechRadar, or PCMag lab review exists. StorageReview rates it a strong value: solid real-world speeds and standout random 4K IOPS, though sequential reads (158.7 MB/s) fall notably short of Samsung's 180 MB/s claim. (1 sourced review, 1 lab-tested.)
Praised: Excellent value for the price versus pricier rivals like the SanDisk Extreme PRO; Standout random 4K read/write IOPS, over 2x the SanDisk in that test; Robust 7-proof durability plus a 10-year limited warranty.
Flagged: Sequential read falls ~21 MB/s short of the advertised 180 MB/s spec; Bundled reader uses a USB Type-A connector, requiring an adapter on modern thin devices.
