Capacity and speed class

This SanDisk Extreme Go SDXC card provides 256GB of storage and carries UHS-I U3 V30 ratings. It targets photographers and videographers who need reliable 4K UHD capture in a standard SD form factor. The rated read speed reaches 230MB/s while write speed reaches 150MB/s.

Durability and environmental resistance

NAND flash technology underpins the card's extreme durability in normal use. The design is temperature proof, waterproof, shock proof and magnet proof so data remains intact across harsh conditions. No active cooling or power management is required for a passive memory card.

Bundle impact

The package contains only the memory card itself with no bundled software or accessories. Users must supply their own card reader or compatible device to achieve the stated transfer rates. No recovery utilities or editing applications are included in the box.

Questions about this item

How do I insert the SDXC card and which slot orientation is the step people get wrong?

Align the notched corner of the SanDisk Extreme Go SDXC 256GB with the slot guide, label facing up, and push until it clicks; forcing it backwards bends the contacts.

What maintenance or replacement will the card need later?

The NAND flash is temperature proof, waterproof, shock proof and magnet proof, so no scheduled maintenance is required; replace only if capacity fills or a device reports read errors.

What limit shows up first during sustained 4K UHD recording?

Continuous write speed tops out at 150MB/s, so long 4K UHD clips will hit that ceiling before the 230MB/s read limit.
