Lexar 1066x 256GB microSDXC Memory Card

Capture

V30 — 4K without drops

V30 guarantees a 30MB/s sustained write floor: what a drone or action cam needs to record 4K continuously without dropped frames, take after take.

Apps

A2-rated for consoles & phones

The A2 application class means faster random reads and writes — the spec that decides how quickly games load from a Steam Deck or Switch card slot, not just how fast files copy.

Offload

Up to 160MB/s read

Pull an afternoon of drone footage off the card at UHS-I’s practical ceiling. SD adapter use in cameras and readers works as standard.

Right choice if you…

✔ Fly a drone or run an action cam in 4K
✔ Expand a Steam Deck, Switch or Android phone — A2 matters there
✔ Want one fast card that moves between devices
✔ 256GB: roughly 6-8 hours of 4K footage or a serious game library

Consider something else if…

✖ You shoot on a full-size SD camera — the Lexar 1667x UHS-II is the faster tool
✖ It’s for a dashcam running 24/7 — that’s endurance work: see the Lexar High Endurance
✖ You only store music on an old phone — a basic card is cheaper

Frequently Asked Questions

Is it good for a Steam Deck or Switch?

Yes — the A2 rating is exactly what helps game loading from microSD. 256GB holds a sizeable library on either.

Can my drone record 4K to it?

V30 sustains 30MB/s write, which covers 4K at the bitrates consumer drones and action cams use.

Why not the 1667x instead?

Different formats: the 1667x is full-size SD (UHS-II) for cameras. This 1066x is microSD — for the devices that take microSD.

Does it come with an adapter?

Yes — an SD adapter is included, so it also works in full-size SD slots and readers.
