archive server with freenas and SMR drives

i decided to build an archive server to store huge amounts of static data, for this reason i decided to get the best price/gb drives and build an raid5/6 from them.

I knew of the possible problems regarding URE during rebuild, but after various test rebuilds using real HDD’s in combination […]
