Our take on the LEXAR High-Performance 633x LSDMI64GBBNL633 64GB Flash Memory, microSDXC

The Lexar High-Performance 633x is a UHS-I microSDXC card rated U3/V30 with read speeds up to 130 MB/s. It suits phones, tablets, action cameras and drones that record 4K video or burst photos. It is a solid mid-tier card: cheaper-feeling brands match its speed class, while premium UHS-II cards write faster but cost more and need a UHS-II reader to show it. Owners rate it well overall, though some report cards that failed early or fell short of the advertised write speed.

Pros
  • U3/V30 rating handles 4K video and burst shooting
  • Read speeds up to 130 MB/s for quick file transfers
  • Works across microSDXC and microSDHC devices
  • Widely available in 64 GB and 128 GB capacities
  • Backed by a limited lifetime warranty in many regions
Cons
  • Write speed is slower than read speed, so large transfers drag
  • No UHS-II support, so it caps out on high-end cameras
  • Some owners report early failures or corrupted files
  • Advertised 130 MB/s read speed needs a UHS-I reader to reach

Questions and answers

Is this card fast enough for 4K video?
Yes. Its U3 and V30 ratings guarantee a minimum sustained write speed for 4K recording, and owners report smooth footage in action cameras and drones.
Will it work in a Nintendo Switch?
Yes. The Switch takes microSDXC cards, and this one has the capacity and speed for game downloads and saves.
Do I need a special reader to get 130 MB/s?
Yes. The 130 MB/s read figure assumes a UHS-I compatible reader; a plain USB 2.0 reader will be much slower.
What is the difference between the 64 GB and 128 GB versions?
Only capacity. Both share the same U3/V30 speed ratings and 130 MB/s read speed.
Does it come with an SD adapter?
Most retail packs include a full-size SD adapter so the card fits standard slots, but check the pack contents before buying.
Is it compatible with phones that take microSD?
Yes, it works in Android phones and tablets with a microSDXC slot, though some phones cap the card's usable speed.
