Professional reviewers consistently commend the Power 128 GB card for delivering near-spec V90 speeds, robust shock resistance, and an industry-leading lifetime warranty with fast replacement. However, they also note that real-world write performance falls short of the advertised peak and that the card's advantage diminishes in UHS-I-only equipment.
No direct consumer reviews were found; most online listings only repeat retailer specifications, so everyday user sentiment is largely unavailable.
Professional reviewers such as B&H consider the Lexar 1800x Gold the "gold standard" for creators needing reliable 4K video and high-speed burst shooting, citing its consistent real-world performance, rugged build and lifetime warranty. While they acknowledge it isn't the absolute fastest option, they view it as offering excellent value and durability for most professional workflows.
