Question Data transfer speeds with Firewire?

Just got a new 4 drive Firewire box with a couple of Seagate 400 gig drives to go with my other 3 Firewire drives. I'm sorting and copying the older drives contents but the transfer speeds seem a little slow, copying around a gig a minute - roughly a 120 gig drive over in 2 hours.

I'm using the 1394a (400M) but wondered if there are any ways to speed it up? Driven from Apple Powerbook.

Thanks!

Mike

Seems slow, though windows I copied 120 gig from external firewire (Seagate) to SATA, and it was Very fast ~10minutes though I did not time it!

Depends on the disc contents, many fragmented files take longer etc.

Thousands of photos or office documents would take ages, yet several 4gb DVD iso files take minutes.

Bear in mind also that whilst USB2 achieves its standard maximum easily; IEEE1394 cant get anywhere near its standard maximum date transfer rate.

What do you mean exactly? Firewire 400 easily outpaces USB2 in my experience when doing hard disk transfers. For a start it supports DMA transfers so requires lower CPU resources.
