SanDisk 128GB Extreme UHS-I MicroSDXC Memory Card

Capture

V30 — 4K sustained

A guaranteed 30MB/s write floor keeps GoPros, drones and 4K dashcams recording cleanly through the whole run.

Fast

190MB/s reads, A2 apps

Offload a day’s footage in minutes, and A2 random performance keeps Steam Deck and Android game loads snappy.

Field-proof

Built for abuse

Temperature, water, shock and X-ray proof — the card for devices that live outdoors.

Right choice if you…

✔ Fly drones or shoot action cams in 4K
✔ Expand a Steam Deck — A2 earns its keep
✔ Offload big footage days on deadline
✔ Want the enthusiast microSD default

Consider something else if…

✖ Pure media storage — the Ultra line gives more GB per pound
✖ 24/7 dashcam loops — endurance cards are built for that
✖ Full-size SD camera — see the SD Extreme/PRO range

Frequently Asked Questions

Is it enough for a GoPro in 4K?

Yes — V30 covers GoPro and consumer drone 4K bitrates with margin; it’s the card those communities standardised on.

Do I get the full 190MB/s everywhere?

Full reads need SanDisk’s boosting readers; standard readers run ~100MB/s. In-device recording speed is unaffected.

Extreme or Ultra?

Extreme: shooting (V30 write floor, A2). Ultra: storing (more GB per pound). Cameras take Extreme; tablets take Ultra.

Steam Deck — worth it over Ultra?

Yes for load times: A2 random reads are what game launches feel.
