    I have a total of six Sandisk USB3 thumb drives and use them for my daily backups, movies and transferring assorted data from computer to computer- great fast and easy transfer. I would recommend that Mac users reformat as they arrive as Fat32. Use disc utility and format the parent (top) as Mac OS X exteneded (journaled).

    This is stupid, kind of like rating a girl on the first 10 seconds of a date. But this is for sales generation only, nothing else drives this kind of blog. So as mentioned above, in a year or two if the thing is still working - then it will be worth rating. Like a date, it may or may not end well. It may drive another purchase who knows.l

    I recently bought this Sandisk Ultra 128 GB to replace my PNY 64 GB. Sandisk seems to have many good reviews and high ratings for quality and reliability. Also, switching to 3.0 usb. for my new computer. The Ultra was noted for excellent speed of data transfer. There is an Extreme model, which is mainly for encryption if that is important to you.
