SanDisk Extreme 2TB microSDXC UHS-I Card (SDSQXAV-2T00-GN6MA) – A2, U3, V30, 4K Video

2TB in a fingernail-sized card, enough for days of 4K footage.

The SanDisk Extreme 2TB microSDXC card gives drone pilots, action camera users, and handheld gamers the largest microSD capacity available in one card. With U3, V30, and A2 ratings, it records sustained 4K video and runs apps and games smoothly, so you can shoot or play longer without swapping cards.

Why Card Speed Ratings Matter for 4K Video

Action cameras, drones, and phones record 4K video at high bitrates. If a card cannot sustain the required write speed, recording stops, frames drop, or the camera displays a card error, often at the worst moment.

The SanDisk Extreme 2TB is rated U3 and V30, meaning it sustains at least 30MB/s of continuous writing, the threshold most 4K cameras require. Its rated write speed of up to 140MB/s adds headroom for burst photos and high-bitrate modes.

At 2TB, this card removes the need to carry and manage a stack of smaller cards. Long trips, multi-day expeditions, and large game libraries fit on one card, which also reduces the risk of misplacing footage.

Faster Offloads After Every Shoot

Read speeds of up to 240MB/s are reached with compatible readers that support SanDisk’s extended UHS-I mode; standard UHS-I readers run at up to about 104MB/s. Either way, transferring footage to a laptop is much faster than with older Class 10 cards.

One Card for Your Whole Library

Handheld PCs and consoles fill internal storage fast. A 2TB card can hold a large library of games, and the A2 rating improves loading for titles run from the card.

How to Set Up the SanDisk Extreme 2TB microSD Card

1. Insert the card into your device with the contacts facing the correct direction, or use the SD adapter for full-size SD slots.
2. Format the card in the device you will record with, so the file system and folder structure match that device.
3. Set your recording mode; for 4K, confirm the camera recognizes the card as U3/V30 capable.
4. To transfer files, use a UHS-I card reader, and always eject the card in your operating system before removing it.
