About the difference between 2.0 and 3.0 drives:

USB 3.0 device can take advantage of a USB 3.0 port for greatly increased data transfer speeds. So the USB 3.0 drive will work faster when plugged into a USB 3.0 port, that's the only real difference.USB 3.0 ports are usually blue, All versions of USB are backwards and forwards compatible- you can plug any version of device (1.1/2.0/3.0) into any version of port (1.1/2.0/3.0) and it will work, just at the slower speed. (IE a USB 2.0 device in a USB 3.0 port will run at USB 2.0 speed, a USB 3.0 device in a USB 2.0 port will run at USB 2.0 speed)

Special Note :

 USB 3.0 drives provide optimal performance only when connected to USB 3.0 ports on the computer and in case the computer does not have 3.0 ports then the transfer speed will be slow.if the flash drive with files over 4.0gb,  format the USB flash drive from FAT on NTFS format.
