بطاقة ذاكرة Promaster 4969 64GB SDXC 633X المتقدمة

The transfer speeds are noticeably faster than my old card, which makes offloading 4K footage much less tedious. It handled a full day of burst shooting without any hiccups. For the price, this is a solid upgrade.

I was worried about dropped frames when shooting 4K video, but this card handled it without a single glitch. The U3 speed rating really makes a difference for continuous burst shots too.

The 64GB capacity is plenty for a weekend of shooting, and the 633X speed moves those large RAW files off the camera noticeably fast. Even with the U3 rating for 4K, it's the read speed that's made my workflow smoother.
