Lexar Blue 1TB
Score: 75/100
ProGrade Digital V90 Iridium 256GB
Score: 75/100Rankings
Lexar 1TB Blue microSDXC provides a massive 1 TB capacity with IPX7 waterproof and shock-resistant construction, targeting gamers and mobile creators. Real-world read/write speeds fall short of the advertised 160 MB/s peak, and optimal performance requires a Lexar USB 3.1 reader. Suitable for users needing high capacity and decent speed for apps and media.
The ProGrade Digital 256 GB SDXC UHS-II V90 card delivers top-tier read/write speeds and robust V90 certification for professional video capture. Its main drawbacks are the premium cost and reduced performance on UHS-I-only devices. Ideal for videographers needing reliable 6K/4K RAW recording in demanding environments.

Professional reviewers praised the Lexar 1TB Blue for its astonishing capacity and solid real-world speeds, noting that it delivers about 97 MB/s read and 62 MB/s write without the need for a high-end reader. They highlighted the added value of a clear storage case and a five-year warranty, but cautioned that the advertised 160 MB/s peak requires Lexar's own USB 3.1 readers and that write performance can degrade during long recordings.
Everyday users love the massive 1TB space for gaming and media, citing fast initial transfers and reliable Switch game installs. However, many complain about write-speed throttling during extended use and the necessity of a specific Lexar reader to unlock full read performance, leading to mixed feelings about consistency versus advertised specs.
