Review on 📸 SanDisk Extreme Pro SDXC UHS-II Flash Memory Card, 128GB, Black by Paul Stocks

This card is very disappointing as it does not have a video speed rating. When I bought the card I didn't know what it was. I've just found that it's not compatible with my CX350 Panasonic camera when set to the maximum. So I contacted Panasonic to find out why. You asked what V# is. I did not know. So I checked it out. This is the graphics card speed rating. How fast can he write. For high quality 4k videos you need at least V60 or V90. The V90 really kills too much because it's designed to be fast enough for 8k footage. But Panasonic recommends the V90 for their camera. So I spoke to San Disk for a video speed rating. They said they don't have them with their new Extreme cards. Big crap! So I looked at their other cards. Your fastest card seems to be the V30. What I'm guessing is one. And why wasn't it marked as such. because it discourages you from buying it. Bottom line: I'd like to know this before my return time expires because it's not even the weight of the paper. It's just not worth the $200 I spent on it. I could get an equivalent V90 card for $235 or less.
