بطاقة ذاكرة SANDISK 256GB Extreme PRO CFexpress 4.0 Type B

The write speeds are absurdly fast—I cleared a full buffer of 4K ProRes shots in seconds and never once stalled waiting on the card during a wedding shoot. It’s held up through two days of heavy rain and constant swapping without a single hiccup.

Editing 4K ProRes files straight off this card felt nearly as fast as working from an internal SSD. The sustained write speed keeps up with my camera's buffer without any hiccups during long bursts.

Went straight from RAW bursts to a full 4K timeline without a single hiccup, and the write speeds are genuinely ridiculous for the price. The card barely warmed up even after an hour of continuous shooting, which I didn’t expect. It’s been rock solid so far, so I’m grabbing a second one for backup.
