It's a non-boot pool. My boot pool is a mirrored pair of 1 TB drives.  I used them because I had them, but I think there's a good argument for keeping the boot pool disks under 2 TB to keep down resilver times for a replacement so that the window of vulnerability to a 2nd failure is minimized.  Losing the  system is a lot more painful than losing some of your data even w/ full backups.

The 3 TB disk is just scratch space.  I haven't abended a job by filling 3 TB, but I have several times w/ a 2 TB filesystem.  A bit annoying to find Monday morning that the weekend job failed because of lack of space :-(
