daisy chaining

[paultreny]

I have a total of 6 hard drives connected to my computer.

Two 500 GB WD Triple Interface daisy chained via FW800

Two 80 GB SmartDisk FireLite and a LaCie d2 DVD±RW Burner daisy chained via FW400

A 300 GB Maxtor OneTouch II and my old 100 GB 2.5 inch internal drive connected via a USB hub.

SuperDuper! backups my 200GB internal drive to one of the 500GB FW800 drives flawlessly, and occurs 4 times a week with no problems. If you are writing lots of data to the drive at the same time as a SD backup, there is definitely a noticeable slowdown, but I've never really encountered any problems beyond it taking a little longer.

That being said, I run SuperDuper at 4 am, and don't run Time Machine at all, so it pretty much has the entire FW800 port to itself, with the exception of the occasional overnight download.

I would take extra care to avoid backing up both SuperDuper! and Time Machine at the same time, it will most likely crawl along at a snail's pace. Take care to schedule them so they don't conflict and I think you'll be just fine.
