if i got a firewire 800 card and firewire ext HD thered be no bottle necking coz there both 800mbps but my HD in my old computer is only ATA 100/133 so between the HD and firewire card wont it be bottlenecked if i transfer between my HD and the ext HD
 
I honestly don't know. I will say unless you have some kind of specific dutys for a firewire hd i would just use usb2 and be done with it. it works fine. besides being more portable. i carry the external hd to other homes and find it useful. firewire is not portable and flexible. a lot of people do not have it anyway.
 
i want to know or should i say i dont understand the speeds of different devices ie usb1 2, ata, sata, firewire because say for example youve got a ata133 HD and you want to copy a file across via eg usb firewire so you plug your cable in your usb or firewire pci card and 32 bit transfer rate is 133 and 64 bit is 266 so how does it transfer it at 480 which is what usb2 is or 800 which is what firewire 800 is, can someone explane
 
Practically you will need to buy a firewire 800 card. The only computers I see with them as standard are:

iMac
Mac Pro
MacBook Pro
 
ive got an ide HD and ive got a file i want to transfer across to usb 2 and of course you know ide speed is 133 and usb2 is 480 so does that mean it will only transfer at 133

PS, also the usb2 card is on my pci bus which is 32bit host running at 133 aswell like the ide channel host so does that mean the transfer speed to the HD and usb2 card will be only 133 instead of 480

ive just done my own homework it took me 40 min to copy my file using my old computer(with the usb pci card and ata 133 HD) but only took me 4 min using my computer (with int usb2 controller and sata 2 drives), all i got to say is that dont buy any pci controller cards, there a gimic coz all your getting is a transfer speed as much as your pci controller card which is 133
 
i talked to some people and did some research for myself and ive concluded the following:
usb=12Mb/1.5MB
usb2=480Mb/60MB
usb3=4.8Gb/600MB

firewire400(1394a)=400Mb/50MB
firewire800(1394b)=800Mb/100MB
firewire s3200=3.2Gb/400MB

so pci can run almost all of them because its got a bus of 133MB but not the new versions of usb and firewire
