Our take on the Lexar LSDMI128BBNL633A 128GB High-Performance UHS-I Class 10 U3 633x microSDXC Memory Card with SD Adapter

The Lexar 633x is a UHS-I microSDXC card rated for up to 95 MB/s reads and a 30 MB/s minimum write speed, with U3 and V30 ratings for sustained video capture. It ships with a full-size SD adapter, so it works in cameras and laptops as well as phones, drones and action cams. It is a budget-tier card: fine for 1080p and light 4K clips, but well short of the write speeds that modern U3 cards from SanDisk and Samsung reach. Its 3.4-star average from 22 ratings points to a mixed record, with reliability complaints dragging it down.

Questions and answers

Is this card fast enough for 4K video?: It carries a V30 rating, so it handles 4K at moderate bitrates. High-bitrate 4K or 6K from mirrorless cameras will exceed its 30 MB/s write speed.
Will it work in a DSLR or mirrorless camera?: Yes, through the included SD adapter. For continuous burst shooting or high-frame-rate video, a faster UHS-I or UHS-II card is a better fit.
Does it work in a Nintendo Switch?: It fits the microSD slot and will store games, but load times will be slower than with an A1 or A2 rated card.
What is the difference between this and Lexar's higher-end cards?: Lexar's 1066x and Professional lines offer much faster writes and app-performance ratings. This 633x card is the entry tier.
Is the SD adapter included?: Yes, a full-size SD adapter comes in the box, so the card fits standard SD slots.
Is it good for a dash cam?: It can work, but dash cams write constantly and heat up. A high-endurance card is the safer choice for that use.
Where is the Lexar LSDMI128BBNL633A 128GB High-Performance UHS-I Class 10 U3 633x microSDXC Memory Card with SD Adapter cheapest?: At Walmart, for $30.99, as of our latest check.
