Thanks for the input guys. Yeah that was the only thing I can really assume to be honest. I don't have any Unix machines to test transfers between them - Probably something I'll set up over the long weekend (the last of priorities however). It seems FreeNAS is not only picky over the hardware it runs on but also the hardware/software it 'runs over'. I wouldn't mind having a dig at some real network gear some day (upgrading to 10gbe) but really for what it is (just a fileserver & streamer) it does almost fine. I'll keep searching and thanks for the heads up Iceman. To Onthax - yes I've already lined up partitions (I think that is one of the tweaks you can do).
