ZFS is pretty bada$$ as long are you have a boatload of RAM and lots of spindles. Putting it on a 1 or 2 drive system seems rather pointless. But I'm still expecting to have it mainstream Linux in a year or so. The de-dupe would be useful for my work but it would require 512GB RAM for the storage size. </p>

<br>
You could save a few pennies and still keep your transfer speed(most of the time) by using ZFS on HDDs and using a 20/40GB SSD as a cache.<br>
You might be able to set up other filesystems to use an SSD cache as well, but I'm not entirely sure.<br>
