Promaster SDXC 512GB Advanced

The U3 speed rating handles my burst shooting perfectly—no lag even with RAW files. Transferred a full card to my laptop noticeably faster than my old card does. Solid performance for the price, genuinely surprised.

4K video recording on my a7III hasn't stuttered once, and the transfer speeds are exactly as promised. The U3 rating makes a real difference when I'm shooting burst mode.

I've been filling this card with consecutive bursts of RAW photos and the write speed keeps up without any stutter. It's been reliable so far and the price was much easier on my wallet than comparable cards.
