Dropping my array size to 6 x 4TBs, I'm looking to offload the old ones.
5 x 3TB WD Green drives, manufacture date August 2012, warranty expiration in October 2014
1 x 3TB WD Green drive, manufacture date August 2011, warranty expiration in September 2014 (not sure why this one's different)
6 x 2TB Seagate LP drives, manufacture date April 2011, warranty expiration in April 2014 (two are newer, replaced under warranty already)
Also comes with a Supermicro SAS card if you're interested, AOC-USAS2-L8i (no backplate though)
No drives are reporting ZFS errors.
Looking for around $600 for 24TB storage total.
