      Just use ZFS.

      Just use ZFS. Especially for NAS. No need to wait.
      ZFS is proven for more then 5 years in production with several hundred TB and tons of disks.
      It is supported under Solaris, OpenIndiana, OpenSolaris, Schillix, Nexenta, FreeBSD, Zfs-FUSE and There is working native Linux kernel module in testing and development.
