Questions, answered

Can SD V90 cards record 8K?

Some bodies allow lower-bitrate 8K modes on V90, but sustained RAW 8K belongs on CFexpress. Check your body's media table per codec; the camera, not the card box, has the final word.

How much capacity does 8K RAW consume?

Roughly 1 to 2 GB per minute in common RAW flavours, and far more in the highest quality tiers. A 512GB card can be a single morning, which is why capacity is a first-order spec here.

Do CFexpress cards overheat in 8K?

They get hot, and bodies manage heat differently. Use the card models your camera maker lists for your 8K modes, keep airflow where possible, and rotate cards on very long takes.

What reader should I buy for CFexpress?

A USB 3.2 Gen 2 or Thunderbolt CFexpress Type B reader from the card maker or a reputable specialist. The reader and cable together decide whether 1,900 MB/s reads are real.
