USB is so badly designed and implemented, it has never come close to the real world speeds seen with Firewire. The increase in speed is minor, at the expense of CPU. Intel not implementing USB3? Perhaps because it’s basically worthless. I just wanted to give your posts some perspective as they read as if firewire could do no wrong while USB failed at every hurdle.
I’m just saying that corners were cut with firewire as well. Now I’m not saying that makes USB > Firewire.
While nobody is disputing that physical machine access opens the system up to a great deal more attack vectors, that also doesn’t mean that firewire should hand them an additional one on a silver platter.ĭMA in firewire was cut corner. What about company workstations? Public access / cyber cafes? Media labs? There are plenty of occasions when a system needs to be secured from it’s physical users. There’s more to security than keeping Joe Blogs safe from the web. To bring up the DMA issue sounds like the death throws of desperation than concerns about genuine security concerns of Ms Sixpack having her machine hacked whilst surfing the internet all because of a firewire port. If someone has access to your machine – you’re f–ked already all the gymnastics in the world won’t change the reality that the would-be hardware hijacker as you by your balls even if you didn’t have a firewire device. Unfortunately the industry is filled with corner cutting, from ‘winmodems’ to ‘winprinters’ to simply aweful promises when it comes to USB technology simply so some dick can save 5cents per unit. The reason why it didn’t win is because firewire has a higher standard to which vendors must abide by – in other words they can’t do the dodgy corner cutting that one could otherwise get away with in the case of USB2 and thus reduce the cost to them at the consumer.Įarly on in the USB development you had a split between those who wanted the hardware to do more of the work and a second group who argued that it would be better done in software then let the CPU carry the load – since the performance of CPU’s are improving rapidly the performance hit should be unnoticeable. And yet how widely used is Firewire these days? Or eSata, for that matter – 90% of external disks are USB-only, and you’ll pay quite a bit extra for eSATA or Firewire support, if you can even find them.
