usb 2.0 questions

[RobCur]

would I get better performance if a pci 2.0 card is used in addition to the onboard 2.0 usb? since the bandwidth is shared.
let's say I attach 3 hd to my computer using usb 2.0, wouldn't the 480mbps becomes 160mbps each so they all max out at 16mb/sec if 3 of them are used at the same time

Each root hub will provide 480 MBPS. You dont really need that PCI card unless you have a shortage of ports - its unlikely you'll get anywhere near the 480 mbps limit in any case.

Thanks,

Also, is it possible to boot your hd from usb ports? Having your hd inside the case you can never tell how noisy it is, you get confused with cpu fan or case fan.

It's possible, but it depends if you're motherboard supports it.

if your mobo supports first boot device as "USB"

my KT333 mobo does. i bet modern mobos all do.
