Lexar SDXC Professional UHS-I 633x 256GB

Lexar is my go to for memory cards... I've never had an issue with them (SD, CF, XQD). They handle read/write as they should and have never given any failures or issues.

I've never had a problem with Lexar. I use a lot of cards because I buy several when Adorama has a sale. If I'm in Rome a few days, I will replace it with a new card when I go to Sorrento. The cards are cheap enough that you don't have to fill them. Rather I can lose a card and I don't lose everything on a long trip.

No problems yet or expected. Works as advertised. Will buy again.

Proven fast and reliable after a few thousand exposures.

Fast enough that my Canons can exceed the listed buffer-limited # of shots when in high speed drive. Never had a failure on a Lexar card; CF or SD. I only use Lexar memory, so my card wallet looks nice when I open it up. Gold CFs and silver SDs. Meaningful details like that really improve my shots....right?
