Nice to see us all singing the same tune... Myself, I use a couple of 2.5" 320GB disks in a zfs mirror for boot, and 500GB disks for my zpool for data...
A note on the whole Sun not recommending individual slices though. It's important to consider *why* they don't recommend multiple zpools on a single physical spindle... Leigh - I have my own ideas, but what is Sun's position on the why... Performance is the obvious one... (I actually have 2 150GB slices on my 320GB disks - and have my current zpool on slice 0 (ie: at the start of the disk, and well away fron the slower inner sectors). But I use slice 1 for an alternate rpool when I feel like it - So it's actually nice. You just need to be a little careful not to get them mixed up. Like trying to have to pools known as rpool on the same disk(s). ;) Nathan.
