SanDisk Extreme PRO 512GB microSDXC — 200 MB/s read, 140 MB/s write
140 MB/s write200 MB/s readA2 · U3 · V30SD adapter included
The SanDisk Extreme PRO 512GB microSDXC card, part number SDSQXCD-512G-GN6MA, is the fastest UHS-I microSD SanDisk makes, at the largest capacity it offers in this line: 200 MB/s read, 140 MB/s write, with A2, U3 and V30 and a full-size SD adapter in the box. At 512 GB the PRO write advantage is real rather than nominal, which is not true at every capacity in this family.
Compatibility — check before buying:
The 140 MB/s write applies from 256 GB upwards. SanDisk publishes 90 MB/s for the 32, 64 and 128 GB Extreme PRO cards, so a buyer choosing the PRO badge at a smaller size pays for read speed alone. At 512 GB the difference is genuine. Read speeds above about 100 MB/s need a reader built for SanDisk faster transfer mode — in a phone, a console or a generic reader expect roughly 100. A2 only does anything on an A2-capable host; elsewhere the card behaves as A1 and nothing breaks. In the box: the card and the SD adapter.
Best For
✓ 4K and high-bitrate video on action cameras
✓ Drones recording long flights
✓ Photographers offloading large cards daily
✓ Android phones running apps from the card
✓ A single card for a whole production trip
✓ Anyone who wants the fastest UHS-I microSD made
Key Features
140 MB/s write, and at this capacity that is the real upgrade
SanDisk write ladder for this line runs 90 MB/s at 32, 64 and 128 GB and 140 MB/s from 256 GB up. Buying the PRO at 128 GB buys read speed only; buying it at 512 GB buys a write speed the standard Extreme cannot match. This is the size where the badge means something.
200 MB/s read is the UHS-I ceiling
No UHS-I microSD in SanDisk range reads faster. If your working day includes getting cards onto a computer between jobs, this is the quickest card that still fits an ordinary microSD slot, provided the reader supports SanDisk transfer mode.
A2 and V30 together
V30 guarantees at least 30 MB/s sustained write for video; A2 guarantees random read and write performance for apps run from the card. This card carries both, so the same card serves a camera and an Android phone without compromise in either direction.
512 GB, with the adapter included
Enough for a long trip on one card, and the full-size SD adapter means it drops into a camera or laptop slot as well. Rated temperature-proof, waterproof, shock-proof and X-ray-proof from -25 to 85 degrees Celsius.

Frequently Asked Questions
Singular Expert Insight
Capacity decides whether the PRO badge is worth paying for on this line, and 512 GB is firmly on the right side of that line. SanDisk publishes 90 MB/s write for the small Extreme PRO cards and 140 from 256 GB upwards, so at this size you are genuinely buying a faster card rather than a more expensive label — 140 against the Extreme 130, and 200 against 190 on read. Both figures on read need SanDisk own reader mode; in a phone or a console both cards land near 100 and the difference disappears. So: buy this for a camera and a proper reader, and buy the standard Extreme if the card is going into a handheld. A card reader built for the faster mode is what turns 200 MB/s from a specification into a transfer time.
Buyer’s Guide
Buy it if
You want the fastest UHS-I microSD available at the largest capacity, and at 512 GB the 140 MB/s write is a real step up over the standard Extreme rather than a badge.
Skip it if
You are buying 128 GB or smaller, where the PRO writes the same 90 MB/s as the cheaper Extreme. Skip it too for dashcam use, where the endurance lines are designed for constant overwriting.
Also consider
The Extreme SDSQXAV at 512 GB reads 190 and writes 130 for less. For continuous recording, the High Endurance and MAX Endurance lines are the correct choice.
