    I've had this flash drive for less than 2 months and I've already lost all of my data that I had stored on it. My only option now is to reformat and hope for the best. I have cheap flash drives that I've used for years with no problems yet my new SanDisk can't make it 2 months without failing. I always thought SanDisk was better than this. Unfortunately, I was wrong.

    The cardboard packaging said 256 GB but the drive ran out of space after copying 32 GB of music. Reformatted - no difference. It was only $20 but what a waste of time!

    The writes slowed fown to a crawl. The reads were still hitting 120Mbps. It is unusable to write data to; it takes 10-minutes to write a 2MB file. Owned for one and a half years.

    Was backing up from my Mac to this device when after 4 hours of use, it “locked” itself in read-only mode and became unusable. This is the second Sandisk USB thumb drive that has died on me. And my last Sandisk purchase.
