That's only true for open source implementations (if you can call ZFS that, the only really decent implementation is still locked up inside Oracle). Netapp's WAFL (which ZFS copied) is the original implementation of a RAID system that is resilient to bit rot and the other array vendors (EMC, HDS etc) all have similar systems.

What features are open source ZFS implementations (ZFS v28) lacking to that on Solaris aside from encryption? I run a 6-drive raidz2 array on my FreeBSD workstation, and I put it through its paces, and it's pretty awesome. Rock solid stable, in my experience.

I hear TRIM support for ZFS is now in the HEAD branch and in the works for FreeBSD 10.
