In this eyeopening video, I decided to push the limits of my CFexpress Type B memory cards by recording in mindblowing 8K NRAW 12bit (NEV) NLOG at 8.3K 60P with a resolution of 8256x4644. The data is being written at an astonishing speed of ~850 Mb/s!

But, here's the kicker – things got HOT, literally! Some of the cards reached a scorching 50 degrees Celsius on the outside, and I'm here to spill the beans on how they managed to survive this intense ordeal.

I dive deep into the overheating issues that cropped up on certain cards, revealing the harsh reality behind the manufacturers' claims. It's time to expose the misleading practices where advertised speeds often turn out to be the maximum read speed or write speed, leaving us in the dark about the true average performance.

Buckle up for a revealing journey into the world of memory card testing, where the cards faced the heat – both figuratively and literally! Don't forget to like, share, and subscribe for more tech adventures! #MemoryCardTest #8KRecording #TechReality #CFexpressburned
