بطاقة Promaster CFexpress 4.0 Type B 512GB Advanced

I was a bit skeptical about the price, but the sustained write speed on this card is genuinely impressive—no dropped frames during 4K recording. The 512GB capacity gives me plenty of room for a full day of shooting without swapping cards.

Switched to this card for a project and the sustained write speed handled constant 4K recording without a single buffer stall. It feels solid and well-built, and after a few days of heavy use, I’m really impressed with the value for the performance.

Bursts of 20+ RAW frames in a row and the write speed never stutters, even when I’m shooting sports. The card runs cool after an hour of heavy use, which is something my old one definitely couldn’t say.
