Firewire - cheap vs expensive PCI card?
We have had issues with our Presonus sounddesk for a while and it seems that Presonus do not support the pci firewire card(s) we have been using (all fairly cheap ones, sub £20) and only show the more expensive ones on their "tested and supported" list.
What I want to know is, why should we spend at least double in some cases to get a more expensive firewire card and would that actually be better/more reliable than a cheaper one? What are the actual differences? I know the better ones have firewire "B" ability but the sounddesk does not to this would be a redundant feature.
Should the cheaper, low-end cards be capable of running this or is there a reason why presonus note we need to get a "beefier" one?
