Lexar PRO 800x 128GB
Score: 63/100Rankings
The Lexar 128 GB 800x PRO SDXC offers solid UHS-I performance with 150 MB/s read and 45 MB/s write speeds, plus rugged durability and a 10-year warranty. It shines for travel and hobbyist creators but may fall short for demanding high-bitrate video or when used with generic readers.
The Kingston Digital 8 GB SDHC/SDXC Class 10 UHS-I card offers rugged durability and a lifetime warranty, with modest 30 MB/s read/write speeds suitable for HD video and standard photography. Its low capacity and limited speed make it unsuitable for 4K or professional cinema applications.

Reviewers describe the SDA10 series as a dependable, high-value Class 10 UHS-I card that hits its advertised 90 MB/s read and 45 MB/s write speeds, making it suitable for most consumer photography and 1080p video needs.
Users praise reliability, durability in extreme conditions, and fast transfer rates, while noting limited speed for 4K and occasional confusion with slower Kingston models.
Professional reviewers praise the Lexar 800x PRO for its solid speed-to-price ratio, rugged design, and V30 rating that handles 4K video well, but they caution that the peak 150 MB/s read speed is only realized with Lexar's own USB 3.1 readers and may drop to about 120 MB/s on generic hardware.
Everyday users appreciate the card's durability in extreme environments, the quick off-loading of files when paired with a proper reader, and the confidence provided by a 10-year warranty. Common complaints focus on write-speed variability under heavy loads and occasional compatibility hiccups with older cameras or readers.
“Perfect for my DSLR - no dropped frames during HD video.”
“Used it on a beach trip - survived sand, water, and heat.”
“Fast transfer speeds and plenty of space for RAW photos.”
