Jason ★★★★★ Oct 21, 2026

Transferring 4K footage off this 256GB card is noticeably faster than my old V30 cards, saving me a good chunk of time after each shoot. The write speed has been rock solid during long continuous bursts, no hiccups.

Samuel N. ★★★★★ Oct 20, 2026

Finally cleared out my old cards and dumped all my 4K footage onto this 256GB without breaking a sweat, and the sustained write speed never stuttered once during a long recording session. The V30 rating actually holds up in practice, which is rare for budget-tier cards.

For RAW photo bursts on my Sony, this card clears the buffer way faster than my old ones, and the 256GB lets me shoot a full wedding without swapping.
