I have a macbook pro 2012 non-retina which has firewire and a 2007 macbook (a white plastic one) which I use as a local server and it also has firewire. In addition to that I have my desktop PC which is a hackintosh build. I know that firewire is kinda obsolete after apple killed it off but I know that firewire has good speeds and it would be great to use for copying big files (I often do). So does it make sense to invest in a PCI firewire card (for like 10-20€) for my desktop PC so I can copy things with good speeds even though firewire isn't used anymore?
Edit: Just ordered a Firewire PCI-E Card for my Desktop (11€) and a 1.8m Firewire cable (5€). I will let everybody know how it works out once I tested everything out.
