Questions about this item
How do I insert this UHS-II SDXC card so the second row of contacts actually engages?
Push the card straight into a UHS-II slot until it clicks; the extra row of pins only connects when the card is fully seated.
Will the V90 rating or the waterproof seal wear out first?
The V90 speed class is a sustained-write guarantee that does not degrade, while the waterproof rating lasts unless the housing is cracked.
What stops continuous 8K recording first — the 250 MB/s write ceiling or the 256 GB capacity?
The 250 MB/s minimum write speed is the hard limit; the 256 GB capacity only determines how long you can record before the card fills.
