When you spend $999 on the biggest, best, fastest phone like the Galaxy Note 9, it says something. This tells me you like having the fastest or best everything.
If so, our last card worth recommending is the Lexar 128GB "Professional" 1000x series card. This isn't your typical microSD card, either. You can get twice as much storage for the same price, but this offers top of the line speed and performance across the board. MicroSD cards are never as fast as the built-in storage, but this comes close.
The Lexar 128GB PRO boasts speeds of 1000x, which comes out to around 150 MB/s read and 45 MB/s write. This means it can read data like mobile games faster, not to mention video, photos and more. Additionally, the U3 rating delivers fast write speeds for recording slow-mo videos.
Sometimes all the rating levels, indicators, and numbers can get confusing. Just know this Lexar is one of the fastest options on the market, and what's inside my personal Galaxy Note 9 already.
