Ready for 4K capture

The Samsung PRO Plus 256GB microSDXC card is built for drones, action cameras and Android devices that record 4K video or run intensive games. UHS-I U3, Class 10, V30 and A2 ratings deliver sustained performance for continuous shooting and smooth app loading. The bundled adapter allows use in full-size SD slots. Six-proof protection guards data against water, temperature extremes, X-rays, magnets, drops and wearout.

Step up from slower cards

This card replaces standard Class 10 or U1 media that cannot sustain 4K recording or fast burst photography. The jump is worth it when your device demands minimum write speeds of 30MB/s for V30 or needs A2 random performance for responsive gaming. Older cards without U3 or A2 ratings will bottleneck recording and app launch times on compatible hardware.

256GB capacity with 160MB/s read headroom

The 256GB capacity holds hours of 4K footage or large game libraries while sequential reads up to 160MB/s cut transfer times to a computer. Write speeds of 120MB/s keep pace with high-bitrate video and rapid burst sequences. The card runs out of space before it runs out of speed, making it suited for extended shoots rather than archival storage.

Questions about this item

Does the 256GB microSDXC card include a full-size SD adapter for cameras or laptops?

Yes, the MB-MD256KA/AM package includes a microSD-to-SD adapter so the card can be used in standard SD slots on cameras, laptops and card readers.

What is the correct way to insert the microSDXC card and adapter so the contacts align properly?

Insert the microSD card into the adapter with the label facing the same direction, then push the combined unit into the SD slot until it clicks; forcing it backwards bends the contact pins.

How do I know when the 256GB PRO Plus card is wearing out and should be replaced?

The card is rated wearout-proof and carries a lifetime limited warranty; replace it if you experience read/write errors, corrupted files or the device no longer recognises the card.
