Mobile gaming microSDXC card

The SanDisk Extreme 256GB microSDXC card is built for mobile gaming and 4K UHD video capture. It delivers read speeds up to 190MB/s and write speeds up to 130MB/s. The A2 rating accelerates app loading so games launch quickly.

Device slot and speed class check

Confirm your phone, tablet or handheld has a microSDXC slot that supports UHS-I U3 or V30 for sustained 4K recording. Verify the operating system can adopt the card as internal storage if you plan to move large titles onto it. Older hosts limited to UHS-I U1 may not sustain the quoted write rate.

Durability and daily handling

The card is rated for temperature, water, shock and X-ray resistance, so it survives travel and outdoor shoots. A bundled SD adapter lets you offload footage to a laptop or camera without a dedicated microSD reader. The compact form factor stays inserted during play, eliminating the risk of losing a tiny card while swapping devices.

Questions about this item

Does the SanDisk Extreme 256GB microSDXC card come with an adapter or reader, or must I buy them separately?

The card is supplied as the microSDXC unit only. Any SD adapter or USB reader required for your device must be purchased separately.

How do I choose between the 256GB capacity and other sizes for mobile gaming and 4K UHD recording?

The 256GB capacity holds many large AAA titles, 3D assets, VR content and hours of 4K UHD footage. Select a smaller size only if your library and recording needs are modest.

What do the 190MB/s read and 130MB/s write speeds mean when the card is inside a phone or handheld console?

Games and apps launch faster because the A2 rating guarantees high random IOPS, while sustained 130MB/s write keeps 4K UHD recording smooth without dropped frames.
