don't get fooled.

gstripe of 4 gmirrors will give 4TB
graid3 or graid5 will give 7TB, but much lower I/O performance (same with
ZFS raidz). if you mainly read/write large files it's OK.
With graid5 read performance is near gstripe only writes are slow, with
graid3 or ZFS raidz both are slow.
To be exact - single reads are not slow, but I/O capacity is low so under
concurrent reads it will be very slow.
