Horrible MicroSD card once half full.
January 11, 2017
Once this microSD card gets beyond half full (say almost 2/3rds) the performance of this microSD card absolutely tanks.
with 70GB filled out of 120GB, my write speeds started averaging in the kb/s instead of mb/s. Below is an image of a performance test I have just run with the SDcard. It's essentially unusable for any OS to store, read/write data to/from. I'm returning this thing ASAP.
Some people will say it may just be my PC. I tested this across 4 different PCs. All had the same results.
