My W550s worked flawlessly with a 128GB UHS-1 Sandisk SD. But with the Lexar 1000X 256gb UHS-2 SD,
it seems to work fine for a while but then suddenly it stops transferring and crashes windows explorer. It has to be restarted and card inserted again for it to work fine for a short while after it happens again.
This card works great on my girlfriends Asus Zenbook.
