I did test this card for 2 things. True capacity and transfer speed. It did pass both. > The read speed was 85MB/s and the write around 45MB/s. > For the true capacity i did just write a 120Gb file with a known sha256 hash and read it back just fine. This only let me conclude that the seller indeed ship me the original sanddisk 128GB card and therefore i do recommend him if you interest of purchasing this product.

Awesome; Performance seems as stated; Works great in "BicBooks"; good idea to store files in external SD for MMC laptops; seems to meet U1, class 10 spec; very fast transfers, store, read; enjoy the 200 dollar laptop revolution! :<)))

Corrupt files everywhere. I'm a computer guy for over 25 years now and I have tried this brand before too. I am having bad luck going from 64 GB to 128 GB SD cards. My pictures and files are good on my Samsung 64 GB card and I make backups of it which are readable. The 128 GB has corrupt files every time and even using different computers and methods to copy. The quality of SD cards in general has gotten very bad.

Had to format this card to FAT32 to make it work in my Nintendo 3DS. Worked 100%. Speed looks as good as any other micro SD card I have bought from Sandisk.

I have been trying to use SD card in my security cam and I thought the camera was not working well. Then after I tried to use the SD card in my new brand dashcam. And SD card doesnt keep videos. I cannot record anyhing. And i tried my dashcam with different SD card, it does work well. Nothing wrong with it. So, SD card is not working. I dont know why. I will return it.
