I Depend On Lexar Cards And Have Since The First Digital Camera I Had As A Professional In 2000. In That Time, I Have Owned Many And None Have Failed. I Depend On Them. I Have 2 Cards In The Camera To Be Safe But The Only Reason I Would Be Looking At The Back Up Is Because I Have Lost The Other Card...not Because One Has Failed. The Speed It Brilliant Now On The Nikon Z9 For Video And I Am Not Getting An Overheating Warning, It Is Designed For The Work.
