The SanDisk Extreme PRO 512GB microSDXC is the working professional’s capacity in SanDisk’s fastest UHS-I line: up to 200MB/s reads and 140MB/s writes with QuickFlow, V30/U3-guaranteed 4K recording, A2 app performance — and the SD adapter in the box. Half a terabyte that offloads on deadline.
Speed
200MB/s — PRO-grade offloads
QuickFlow pushes reads to 200MB/s with a compatible reader — a day’s 4K lands on the laptop while Extreme-class cards are still working. 140MB/s writes keep bursts and high-bitrate video fluid.
Capacity
512GB — the shoot-day sweet spot
Roughly 16 hours of 4K 30fps or 100,000+ photos: a serious shoot day or a long trip per card, at a friendlier price per gigabyte than the 1TB flagship.
Reliability
Four-proof, recovery included
Temperature, water, shock and X-ray proof, with RescuePRO Deluxe recovery in the box — one recovered shoot pays for the card.
Right choice if you…
✔ Shoot professionally and offload on deadline
✔ Want SanDisk’s fastest UHS-I line at the practical capacity
✔ Move one card between drone, action cam and DSLR
✔ Value a guaranteed V30 floor over peak-figure marketing
Consider something else if…
✖ Deadlines are relaxed — the standard 512GB Extreme records identically for less
✖ You need the full terabyte — see the Extreme PRO 1TB
✖ You loop-record 24/7 — High Endurance is the purpose-built line

Frequently Asked Questions
PRO vs standard Extreme — worth it at 512GB?
In-camera both are V30, so recordings are identical. The PRO’s edge is offload speed and heavy burst work — if your time after the shoot matters, yes.
Do I get 200MB/s in any reader?
Peak needs a QuickFlow-compatible reader; standard UHS-I reaches ~104MB/s. In-camera performance is unaffected.
How much 4K fits on 512GB?
Roughly 16 hours of 4K 30fps footage, or over 100,000 high-resolution photos.
Steam Deck / Switch suitable?
Yes — A2 random reads suit game loading, and 512GB holds a serious library.
