    The Sandisk Ultra USB 3.0 128 GB drive serves my purposes well. I use it to exchange dance videos with my dance instructor, and the transfer speeds are approximately 55 MBps on my 2010-era desktop. I have had no problems with this drive; I bought two of them, and both work very well. The drives come formatted as exFAT drives, which I appreciate, since this format can hold enormous files, and can be read natively by Windows and Mac OS.

    When it comes to transferring data, SanDisk USB drive is my favorite external storage device I prefer using because I find it to be more reliable than some of the others I've used. This one is the choice I use for my laptop and music in my car's media system.
