Re: Good cables are better
"I wonder why four people down-voted, there's nothing inaccurate about saying the DMA of firewire is a huge security risk."
I suspect the downvotes were due to the implication that because of the security risk, Firewire was a stupid or worthless system with no useful application.
Given that Firewire was offering 400-3200Mbps at a time when USB 1/1.1/2 was offering 1.2-480Mbps, the use case for demanding video and photographic applications was overwhelming. And piping video back from your GPU to get to the USB controller is indeed a stupid and wasteful thing to do.
In a closed environment where you used Firewire exclusively for importing material from your camera, etc it was the choice between getting on with it or leaving it overnight, and realistically caused no significant security risk.
The gap has closed now, with USB 3/3.1 offering 5-10Gbps, which in most applications far outstrips the I/O of connected hard drives, cameras or memory devices, rendering the speed advantage of Thunderbolt to be less than compelling for all bar the most demanding users, who will potentially find a means of hooking up their Red Rocket direct via a PCIe breakout port (which is what TB is effectively) very useful on laptops or mobile workstations.
That's hardware which would - in a conventional tower or workstation be connected via PCIe anyway. Therefore providing a means to connect it to devices without conventional PCIe slots (like laptops) has value, and doesn't put your system at any more risk than it would be anyway - provided you treat TB like your genitalia and take care what you do with it and who you give access to...
