Yes. 4-way on the bigger drive is *more*

It should be safe but chances are that your new 2TB disks are
considerably slower than the 1TB disks you already have. This should
be as much cause for concern (or more so) than the difference in raidz
topology.
Not necessarily for a home server.

RAM:
24 GB (12 x 2GB)
10 x 1TB Seagates
Just a quick update, Tested using bonnie++ just during its Intelligent write:
my 5 vdevs of 4x1tb drives wrote around 300-350MB/sec using that test.
The 1vdev of 4x2TB drives wrote more inconsistently, between 200-300.
This is not a complete test... just looking at iostat output while bonnie++

Hi,
(Main questions at bottom of post)
I recently discovered the joys of ZFS. I have a home file server for
backups+media, also hosting some virtual machine (over LAN).
I was wondering if I could get some feedback as to whether I have set things up

Drives:
20 x 1TB (Mix of seagate
