Sure it does.
This is load-share, not RAID0. Also, to answer the other fellow,
since ZFS does not support RAID0, it also does not support RAID 1+0
(10). :-)
With RAID0 and 8 drives in a stripe, if you send a 128K block of data,
it gets split up into eight chunks, with a chunk written to each
drive. With ZFS's load share, that 128K block of data only gets
written to one of the eight drives and no striping takes place. The
next write is highly likely to go to a different drive. Load share
seems somewhat similar to RAID0 but it is easy to see that it is not
by looking at the drive LEDs on an drive array while writes are taking
place.
