Yes, the Samsung PRO Plus 256GB SD is compatible with the Sony ZV-1 Mark II.
Sony ZV-1 Mark II's own Help Guide states its fastest 4K mode (XAVC S 4K 100Mbps) only requires an SDHC/SDXC U3 card -- well below this card's real 90 MB/s write speed. Samsung PRO Plus 256GB SD clears that floor with margin (unlike higher-bitrate camera bodies elsewhere in this DB where this same card lands as degraded/conditional, ZV-1 Mark II's own floor here is low enough that it clears fully).
“XAVC S 4K 100Mbps* SDHC/SDXC card (U3) XAVC S HD 100Mbps SDHC/SDXC card (U3)”
“U3 (UHS Speed Class 3) per the SD Association spec guarantees a minimum sustained write speed of 30 MB/s. Samsung PRO Plus's own real 90 MB/s write speed exceeds that floor.”
