SanDisk Extreme Pro microSDXC 200MBs 256GB

SanDisk Extreme PRO 256GB microSDXC | 200MB/s | UHS-I | U3 | V30 | A2 | 4K UHD

The SanDisk Extreme PRO 256GB microSDXC is where capacity meets elite performance. Powered by SanDisk QuickFlow Technology, it hits read speeds of up to 200MB/s — and unlike the 64GB and 128GB models, the 256GB steps up to a significantly faster write speed of 140MB/s. That means faster in-camera writing, smoother 4K recording, and a post-production workflow that finally keeps up with your creative output. This is the card built for creators who shoot heavy, edit fast, and never stop.

Why the SanDisk Extreme PRO 256GB microSDXC Is a Step Above

⚡ 200MB/s Reads + 140MB/s Writes — The Fastest UHS-I Combo

The 256GB Extreme PRO isn’t just bigger — it’s faster where it counts most. With write speeds of up to 140MB/s (vs. 90MB/s on the 64GB and 128GB), this card pushes data to storage faster during shooting — reducing buffer lag in burst mode and enabling more sustained 4K recording without slowdowns. Paired with 200MB/s read speeds via QuickFlow Technology, offloading an entire day’s shoot takes minutes.

Pair with the SanDisk Professional PRO-READER SD and microSD (sold separately) to reach peak transfer speeds.

🎬 Uninterrupted 4K UHD Video — At Scale

Rated V30 (Video Speed Class 30) and UHS Speed Class 3 (U3), the Extreme PRO 256GB guarantees a minimum sustained write speed of 30MB/s — the highest possible for UHS-I. With a 140MB/s write ceiling, 4K UHD recording, cinema-quality video, and high-bitrate footage all flow seamlessly. With 256GB of space, that’s over 22 hours of Full HD video or more than 2,200 minutes of 4K content on a single card.

📸 High-Volume RAW Burst Shooting — Cleared Fast

For photographers pushing their cameras to the limit, the 256GB Extreme PRO offers something the smaller models can’t — the ability to sustain longer burst sequences before the buffer fills. The faster 140MB/s write speed means the camera clears the buffer faster, so you’re back to shooting sooner and missing fewer shots.

📱 A2-Rated for Maximum App Performance

Certified A2, the Extreme PRO 256GB delivers 4,000 read IOPS and 2,000 write IOPS — the fastest app performance class available on microSD cards. Whether you’re running demanding applications, games, or media apps on an Android smartphone, this card handles it without hesitation.

🛡️ Engineered for the Most Extreme Conditions on Earth

Wherever the shot is, this card goes:

• Waterproof — survives rain, submersion, and moisture
• Shockproof — rated for drops, vibration, and impact
• Temperature proof — operates from -13°F to 185°F (-25°C to 85°C)
