It work great in my Asus Tablet for 3 months then it just completely died. It was not recognized by any of my devices. It had just died.I have RMA'd it to Sandisk. The prcess was painless and my replacement should arrive within a few days. They emailed me a return label thru UPS and sent it off last week.When it worked the performance was great and access times were very fast. No lag in reading and writing data.If you get this just make sure you have a back up of your data incase of failure. Had my Tablet synced to my cloud service so I did not lose anything. I have purchased other Sandisk items and have never had a issue.
