SanDisk Extreme Pro 128GB microSDXC 170MB/s A2 V30

SKU CH-5H44-14946

High-capacity microSDXC card delivers 4K video recording with 170MB/s read speeds and A2 app performance

  • Read speeds up to 170 MB/s for fast file transfers
  • Write speeds up to 90 MB/s for smooth 4K video capture
  • A2 rating accelerates Android app loading and performance
  • V30 and U3 ratings guarantee sustained 30 MB/s video recording
  • Temperature, water, shock and X-ray proof for extreme conditions

Built for extreme conditions

The SanDisk Extreme Pro microSDXC card is rated temperature proof, water proof, shock proof and X‑ray proof. It targets creators and mobile users who need reliable storage in harsh environments. The A2 rating means Android apps launch and run faster directly from the card. It suits anyone capturing 4K video or expanding phone storage where durability matters.

Adapter included for flexible use

A standard SD adapter ships in the package so the microSDXC card fits full‑size slots in cameras, laptops or card readers. This lets you move 4K Ultra HD footage to a desktop for editing without a separate reader. The adapter does not change the card’s speed ratings; it only provides physical compatibility across devices.

UHS‑I U3 V30 speeds for 4K workflow

The card meets UHS Speed Class 3 and Video Speed Class 30, guaranteeing a minimum sustained write of 30MB/s for uninterrupted 4K recording. Read transfers reach up to 170MB/s while writes hit 90MB/s, cutting offload time after a shoot. Class 10 compliance ensures baseline performance for full HD capture on older hardware.

Questions about this item

How often will the card need reformatting or replacement if I write to it daily?

The card is rated temperature proof, water proof, shock proof and X-ray proof, so it resists the physical wear that usually forces early replacement.

Which speed limit will I hit first during long 4K recording sessions?

Sustained write speed is capped at 90 MB/s by the U3 and V30 ratings, so that is the bottleneck before the 170 MB/s read ceiling.

Does the card get hot or draw noticeably more power when recording 4K all day?

The UHS-I interface and V30 class are designed for continuous 4K capture without thermal throttling or excess power draw.
