Pretty good drives.
These are in a RAID in an FNAS, The performance isn't bad at around 98MB/s write speed, RAID 6 setup.
Only 2 out of 10 have failed in 1 week but out testing software results showed the 2 drives had very long running times in the S.M.A.R.T readings.
Due to age of these drives if you get 2011 or around this year please expect some to fail weather it be a week or in a few months due to run time, Unless they are BRAND NEW ie they are 2011 drives BUT been sat in a box until you use them.
HGST are pretty good drives as well.
