Awesome product, but you'll need SanDisk's proprietary MobileMate USB 3.0 reader to reach the max speed. The reader costs about $10, so no biggie for me. With a normal card reader or my laptop's SD card slot, read/write speed was around 90MB/s, which was still very, very good. I was able to achieve higher than advertised speed using the MobileMate reader, 177MB read vs 101MB write. These are truly incredible speed for a micro SD card. Highly recommend!

Bought this the other day to go in my samsung note 9 wife and i just had lil girl and wanted to add memory to the already 128 pn board so now all my photos and video automatucally go onto this sd card...this thing works perfectly with my phone.. cant believe the memory on such a small card but easy to install amd all my vids and photos are crystal clear if i remember right this card is also shock.. dustproof and waterproof all i know is ive always used sandisk sd cards this one rocks and the adapter it came with works for me putting it into computer and such ... great price got mine for either 17.99 or 19.99 during 12 days of xmas sales this year... Thank you Best Buy... i will always keep coming back!!!

I use this for my drone, high speed, quick transfer time, trusted brand. Get one for you

I have a Raspberry Pi kit that came with a less storage with class 10 performance. Raspbian imaged on the card and the boot times were about where I expected it to be, about 30 seconds to 1 minute. Then I tried this card, the SD Extreme Plus. What a difference in speed. Boot times now range in the 15 - 20 second range. Launching programs felt a bit snappier, and compilation times for larger C or Rust programs were faster. This could be due to factors such as increased disk speed for RAM paging read/write.

I recently purchased the Hero7black and needed the microSD. This will save fast enough for 4k video and has plenty storage. Comes with full sized SD adapter and a small case. Perfect to keep in the laptop bag for easy transfer of files.
