This BESY microSD card is rated V30, U3, A2, and Class 10, delivering up to 80MB/s read and 30MB/s write speeds for smooth 4K video recording and app performance on phones, cameras, and action cams. It's available in 32GB, 64GB, 128GB, and 256GB capacities.
Like all flash storage, displayed capacity runs slightly below the rated capacity due to differences between decimal and binary measurement — a 128GB card typically shows around 100-120GB of usable space, which is standard across the industry.
