256 GB microSDXC for apps and video

This SanDisk Extreme Pro card delivers 256 GB of storage in the microSDXC form factor. It carries an A2 rating for faster application loading on phones, tablets and handheld consoles. The bundled SD adapter lets you use the same card in cameras, laptops and card readers without extra accessories.

UHS-I speeds with V30 and U3 ratings

The card meets Video Speed Class V30 and UHS Speed Class U3, guaranteeing a minimum sustained write of 30 MB/s for smooth 4K capture. UHS-I bus interface keeps power draw low during continuous recording. Class 10 compatibility ensures it works in older devices that only require the baseline speed tier.

Durable build with adapter flexibility

SanDisk rates the card for temperature, water, shock and X-ray resistance so it survives daily transport in bags or pockets. The included full-size SD adapter clicks securely into standard slots, removing the need for a separate dongle. MicroSD dimensions keep the package small for devices with tight internal clearance.

Questions about this item

How do I install the microSDXC card and what is the step users often get wrong?

Insert the microSDXC card into the device slot with the gold contacts facing down until it clicks; the step users often get wrong is forgetting to use the included adapter when the device only accepts full-size SD cards.

What maintenance or replacement will the card need later?

The card itself requires no scheduled maintenance; replacement is only needed if the 256 GB capacity fills up or if the card fails after extensive write cycles.

What limit shows up first under sustained video recording?

The V30 rating guarantees a minimum 30 MB/s write speed; sustained recording at higher bit-rates will hit that speed ceiling first.
