Can a USB 2.0 be upgraded to a USB 3.0

I have an older G- speed 8tb unit that has a USB 2.0, FW800 & eSata.
I am wondering if the PC board can be replaced to upgrade to a USB 3.0.

Just changing the board will also change the RAID controller and the data in your unit will not be compatible and will require re-creating the RAID from scratch. You would need to buy another G-Speed Q that has USB3.0 and swap the drives.

Just a board is not available anywhere that we are aware and certainly isn’t supported.

I appreciate your help, I’ve just bought the unit and was hoping to upgrade
the inputs to a faster system before I start using it. I will go back to my
original plan of using the eSata.

thanks, John Weber
