FYI: as of Solaris Express 11, disk usage is reported correctly:
"zfs list" will show the size of the volume (minus parity)
"zpool list" will show the size of the volume (including parity)

In fact 30% is almost like having 2 disks space available in 3 disk RAID-5 array, right?
I would consider them the same in general - done in hardware or software, still requires a drive for parity.

Would it be correct to assume that utilizing raidz would make data about 30% bigger in size but with the advantage of having an ever-expanding RAID-5? As to say that instead of having the typical trade-off of a RAID-5 with the array minus one HDD... and in this case roughly 30% file size increase? Just wondering.
