بطاقة SanDisk Extreme PRO 512GB CFexpress Type B سرعة كتابة 1400 ميجابايت/ث وسرعة قراءة 1700 ميجابايت/ث

Switching from Sony's Tough G series, this card's 1700MB/s read speed clears my buffer almost instantly after a long sequence of high-res raw captures. The sustained write performance is exactly what I needed for 4K 60fps video without any dropped frames.

Shooting back-to-back bursts on my A7IV, the write speed never stutters—even the 1400MB/s spec feels conservative in real use. Offloading 512GB of raw files takes maybe five minutes over my reader, which is stupid fast. Already ordered a second one.

The buffer on my camera cleared instantly during a wedding shoot—I never once hit a lag while firing off continuous raw bursts. 1400MB/s write speed is no joke, and the card stayed cool even after an hour of 4K video. This thing eats files for breakfast.
