I'm I guess what they consider a power user. I take up a lot of storage, have always used the higgest capacity sd cards. Currently I am using the 512 GB Samsung Evo+ I got when it was released. I know Sandisk makes a 1TB, does anyone have any info on when Samsung will release their 1TB Evo+? While Sandisk is decent for file transfers I wouldn't rely on them as a primary sd card.
