1TB drives are right on the border of switching from RAIDZ to RAIDZ2.
You'll see people argue for both sides at this size, but the 'saner
default' would be to use RAIDZ2. You're going to lose storage space, but
gain an extra parity drive (think RAID6). Consumer grade hard drives are
/going/ to fail during a resilver (Murphy's Law) and that extra parity
drive is going to save your bacon.
