Topic: RME Audio Fireface 400 help

Hello,
Owner of a RME Audio Fireface 400 with 2 firewire 400 ports, I would like to know if it it possible to find adapters to USB3 or Thunderbolt or is it better to use a simple Firewire card connected to the motherboard?
What is the best solution as I would change Motherboard but no firewire connection on new one and keep the best data transmission speed.
Maybe another better suggestion?
Thank you in advance!
