Lexar 4TB CFexpress Type B Reviews
The gold standard

Memory cards will eventually fail, especially if they are put through heat, and heavy use cycles. This is the M1 Abram’s Tank of memory cards. Transfer speed and superior video quality retention across the board. Why risk that valuable footage to inferior memory? The truth is and will always be, you shouldn’t!
Lexar cards are great!

I have one already that I use in my z9 for video of wildlife. With this great deal I figured I would get another one. These should be great in the z92 when it comes out
