modern SATA drives fail VERY often. about 30% of drives i bought recently 
failed in less than a year.

ZFS copies are far from what i consider useful.

for example you set copies=2. You write a file, and get 2 copies.

Then one disk with one copy fails, then you put another, do resilver but 
ZFS DOES NOT rebuild second copy.

You need to write a program that will just rewrite all files to make this.
