Just remember, ZFS is not the holy grail.
There are many aspects of ZFS implementation detail that can have the capability to **** on you from a great height in terms of the integrity of your data if you don't do it right.
ITS NOT just a case of going "oh hey, I'll just reformat this lot as ZFS".... this is not EXT4 with a bit of LVM...
If you're working with consumer-grade hardware you have to be doubly careful, because that sort of stuff makes many assumptions on behalf of the non-techie. Consumer-grade also has somewhat different failure modes to the commercial stuff, and ZFS
needs consistent, fast and predictable failure modes.
And even if you get your implementation right, a bug can still ruin your day, just ask the BBC who were one of the first "big names" to jump on the ZFS bandwagon ... legend has it they came very close to loosing a shed-load of data and required much handholding by the gurus at Sun to get the ship upright again.
