I have been using a older computer with USB2.0 for the past 9.5yrs. This new computer does have USB3.1 at the back of the computer, as I am using my old case my USB ports on the machine and on my Dell Ultrasharp screen is only USB2.0. Even many computers sold last year might had only USB3.0 rather than 3.1. Even now, many computer cases the front USB ports on the case are only 3.0. USB3.0 worthy of an upgrade? Camera memory cards will need to be the faster ones right .. Eg ..Sandisk Ultra SD prob not require USB3.0 right? Also, what do you guys use as a memory card reader and is that USB3.0, or 3.1? Thanks.
