Seems very fast I can almost shoot continuous 20fps full raw on the Z9 and the buffer only just slows down when it does hit the limit. And just a quick lift and its fully cleared in less than a second. Most impressive and it stays fairly cool. Wont know about longevity until I use it for a year or so but looks really good so far.

It's a memory card from a reputable manufacturer. According to reviews, at the time of purchase, it has the highest burst rate. I got it to go with a new Canon EOS R5. So far no complaints.
