بطاقة SanDisk Extreme PRO 256GB CFexpress Type B سرعة كتابة 1200 ميجابايت/ث سرعة قراءة 1700 ميجابايت/ث

Shot a full 4K wedding on this card and never once hit a buffer limit, which was a huge relief. The 1700MB/s read speed makes dumping 256GB onto my laptop in just a few minutes.

The sustained write speed of 1200MB/s cleared my buffer in seconds during a burst of RAW shots, which was the bottleneck I had with slower cards. It reads back footage fast enough that my editing workflow feels seamless now.

Switching from my old card, the write speed alone saves me a solid few minutes after every shoot—those 1700MB/s reads make culling files on the laptop feel instant. The 256GB capacity is plenty for a full day of 4K footage without swapping cards.
