Questions about external drives

[MartyStickle]

I've got a new WD My Book 1 TB drive and have not yet set it up. I'm using an imac with SL with a 250G drive about half full. I"ve got a FW external (160G) to which I've cloned my main drive (I do this about once per month). I've also got a another 250 G USB drive partitioned into a small BU drive and Time Machine partition. I also use MobileMe backup to do my data files and settings. Anyway, it's kind of all mixed up. I'm thinking of partitioning the new 1 TB drive into maybe 250G time machine and the rest backup for my photos, music, etc.

I'd love to hear some other suggestions.
