Comments about Belkin Belkin 6 Port Firewire Hub Supports 6 Pin with Throughput of up to 400Mbps.:

This is a great product for anyone with multiple FireWire products and only a few or one FireWire ports on your computer. I used to daisy chain my three external hard drives together, but heard speculation that doing so might damage certain components (perhaps during a power surge, although I'm not certain; a Google search turns up many reviews of daisy chaining).

Being paranoid of the data I have stored on these hard drives, I decided to invest in a FireWire hub. This one works great, and apparently doesn't even need to be plugged in to function (although I use the supplied power cable, since I have access to a plug).

It comes with a FireWire 400 cable, in case you don't have a spare to attach it to the computer. It seems to work as fast as things ran before I got the hub.
