I've not tried 2.5.x which may be way better here. As a random data point, we're using external USB2 Maxtor IDE drives (they also have firewire support, but the weird grille on the back of our server prevented the firewire plug from properly inserting into the combo USB2/firewire card I bought) for our backups on 2.4.21-rc1-rmap15g, and I was seeing around 10Mbyte/sec when I was monitoring it the first couple times. It's also been much more reliable than the tape solutions we've tried, and it's hard to beat the price. --=20 Zed Pobre a.k.a.
