That's what I was trying to get at by that statement. This is really what made ZFS standout over other types of file systems. In doing that according to everything I have read, it actually means faster I/O and ease of portability incase the disks need to be removed from their current location and added elsewhere but not loosing information. Unlike clunky hardware RAID systems ZFS adds much more versitility too which of course being at this depth of knowledge you are aware of and may even have a means to compare, however I personally prefer it over RAID as RAID is rubbish dealing with it everyday I am fed up of creating non-dynamic arrays. I cannot compre directly to the more advanced UFS2 techniques but my money would be with ZFS over RAID and LVM any day and don't even give me M$ systems they would be out the window before being booted for the first time......
