Apple's USB (and some of the G5 Firewire) implementations are quite poor. This is well documented via benchmarks at sites like barefeats.com. I've never found (but haven't really looked either) an explanation for why this is. USB 2.0 works much better under Windows - don't know about Linux. (Interestingly enough Windows sometimes cripples Firewire to ensure compatibility. You have to tweak registry settings to get full performance.) That being said, when I found USB 2.0 cases for $10 after rebate I decided I could live with slow backups. Phil
