    • SOLID RELIABLE CF EXPRESS CARD
Capacity: 320GB Style: CFExpress Type B
After 4 months of normal and rigorous daily use with my Nikon Z6iii, this card has proven to been an essential tool for my high-end video production (Performance, Speed and Reliability) From 1080p/240 to 6K internal RAW recording, the card has been reliable without any throttling or frame drops. My Z6iii gets warm using 6k but the card has shown to handle that pretty well. (I haven't had a chance to test/use this in extreme gre heat as of yet) But no heat warnings under current conditions. Buffer clears very fast on stills so no need to get into that. A SOLID RELIABLE CARD that i highly recommend. ... show more

    • Great Card!
Capacity: 320GB Style: CFExpress Type B
Initially I was leery. Why 320gb? Why an odd number like that? But this was only slightly more expensive than the 256gb card I usually get. And it could be shipped sooner. So I got it. And it is a FAST card. I never get buffering when taking photos, and the video has been smooth. I am shooting with a Canon R5. ... show more

    • Test the card before trusting it
Capacity: 320GB Style: CFExpress Type B
I had an issue with the original memory card. It would not record and would not be recognized by the camera or computer. After some correspondence, I sent in the defective card and was sent a new one. The card gets very hot.

    • Good price
Capacity: 320GB Style: CFExpress Type B
Haven't use a lot yet, but overall the pricing point seems good. I haven't run into any issues recording at 4K but haven't pushed it yet to see how it stands up to 8K recording. Will report back if any issues.

Capacity: 320GB Style: CFExpress Type B
I like it. It's faster than what I previously had (SDXC). However, I can't compare well because it's my first experience with a cfexpress card.
