Dead 2TB drive on G-Speed Q, can i still get it replaced?

So it looks like I may have a dead drive on my G-Speed Q. Yellow light on drive and red light flashing on chassis Can i still get replacement drives for it, and if so where? It’s raid 5 so will it rebuild still? It mac formatted and current os is 10.12.6

If you pull one of the drives out it will have a PN on it. That is what you will need to search for online to find a replacement.
