    Firewire or USB 2.0?

    So i'll give you my situation and let me know what you guys would do.

    I currently have my images on an external 500GB RAID 1 set up, it has both USB 2.0 and 1394 connectivity. I am putting together a new photo editing machine and am trying to decide if I should bother to spend the extra $$ to get a mobo with 1394 (about $60-70 more) or if I should just hook the raid up via USB.

    USB 2.0 transfers data at 480 Mbit/s, 1394 at 393Mbit/s, so USB 2.0 is faster in that sense. However from what I understand the 1394 interface has it's own chip, therefore not using CPU resources like USB does, or at least less resources.

    I am wondering about real world performance, will it be worth the extra cash to go 1394?

    Thanks!

    Re: Firewire or USB 2.0?

    What I have seen USB 2.0 is always faster then Firewire. I have used both and now use only the USB.

    I tested my external DVD-RW with both and the USB beat the firewire by alot.
    Burn a full dvd on firewire ws like 45 min to and hour, USB was taking 15 to 25 min.

    This was using a 1394 card on a Intel 3.0 cpu and 2 gigs of ram.

    Hope that helps

    Re: Firewire or USB 2.0?

    You probably had a setting wrong. There is a setting in Windows that can limit firewire speeds to s100 (100Mbits/sec) rather than its usual 400 or 800.

    When set up properly, FireWire has a significantly higher sustained transfer speed than USB 2.0. USB 2.0's 480Mbits/sec transfer speed is a theoretical burst max, which is rarely achieved and sustained speeds are significantly lower. FireWire 400 set properly achieves a sustained throughput of just about 400Mbits/sec.

    Thats what I was thought too, otherwise the Ieee 1394 standard would be dead. USB 2 supports (and backwards supports) so many devices that if 1394 didn't have some advantage (speed) it would be useless.

    I decided to go with the mobo that has 1394

    Re: Firewire or USB 2.0?

    I would go with Firewire, but USB 2.0 is commonly used for other applications as well. I know that a lot of industrial cameras use firewire because it requires the speed firewire offers. If you want to know more, you should visit newnex.com. I usually buy my cables from them because they can customize any cable the way I want it. They also offer a lot of information on Firewire as well as USB 2.0 if you're still deciding.
