## What reviewers say

Only StorageReview, one whitelisted lab, hands-on-benchmarked this exact 512GB card. It measured 191MB/s read and 133MB/s write, at or near SanDisk's ratings, plus class-leading large-block sequential speed. The card trailed Samsung's PRO Plus on 4K random IOPS and fell just shy of its 200MB/s read spec. Single-source; no cross-tester corroboration. (Based on 1 review, 1 lab-tested, 2022-09-13.)

Praised: Sequential read/write hit at or very close to rated specs (191/133 MB/s); Class-leading large-block sequential performance, beating Samsung PRO Plus; Rugged (water/temperature/shock-proof) with lifetime warranty; easy to recommend.
Flagged: 4K random performance trails Samsung PRO Plus (601 vs 834 write IOPS, 1,349 vs 2,505 read IOPS); Measured read of 191.1 MB/s fell just under the rated 200 MB/s.
Disagreement: No cross-source disagreement possible: only one whitelisted tester (StorageReview) with hands-on measured data for this exact 512GB model was found. All praised/flagged points rest on this single source.
