I am going to start spending a little more money if needed and start buying Transcend. The one Transcend thumb drive I've purchased, 64G, works great and always has. The SanDisk 64G thumb drive always had some kind of annoying problem until it finally quit working. Everything I've been told to do to reformat and reset it doesn't help. And FYI, I ALWAYS ejected the drive before I disconnected it. These memory cards from SanDisk that I've bought also have these little headaches all the time. All my Transcend work great and they have been faster to copy my 40G worth of music to. Spend the little extra money if need be and buy the Transcend.
