My 64GB FIT has run very hot from day 1 when copying files or formating. It is so hot I can’t touch the metal part for more than 2 sec while in use and I have to wait a few min to cool down after pulling it out. While at idle it is just slightly warm. I only use it in a 3.0 port on my 1 year old MSI gaming laptop. It obviously is not a hardware issue since there are so many reported heat problems even in new computers. A design flaw in the Fit has to be the problem . I’m also getting terrible write speeds of only 23MB/s when it should be around 100 MB/s. My read speeds are better than spec at 145MB/s but that doesn’t make up for the write speed. I will not get any more Ultra Fits at any price, I will try the Extreme 64GB next.
