USB2, whether USB2 port or USB3.0 port, ideal for backing up important small files, e.g. B. Documents, text files, small images, etc. For small file types, transfer is quick and easy. The colors are good for distinguishing the different tasks each disc is used for. I use three of these, one for each home computer on our general purpose computers. I also use a sharpie pen to label each disc. Two of these are for my personal gaming computer to backup the BIOS profile and keep the latest BIOS and LAN driver updates. While everything is already backed up to the second internal drive, it is "required" to flash the BIOS via a USB 2.0 drive formatted with Fat32 (the default format) when it arrives.
