The Lexar High-Performance BLUE Series 633x is a UHS-I microSDXC card rated up to 100 MB/s read, sold in 256 GB with an SD adapter. It targets phones, tablets, action cameras and drones that record 1080p and some 4K. Class 10 and UHS-I speed are enough for everyday video and photo capture, but the card is not rated for the sustained write speeds that 4K at high frame rates or 360 cameras demand, where UHS-II and V30-rated cards do better. Buyers get large capacity and an adapter for laptop transfer; the trade-off is modest write performance and a mixed reception on long-term reliability.

Ratings are middling, with buyers split between those who find it a solid, roomy card for phones and cameras and those who report failures or slower-than-expected writes.
