HI Guys, had 6 of these (4TB version) and 100% are dead. For one i RMAd it, got a new one and the new one died again as well! Used with MOBO sata and broadcom controller. Scanning 3 which are still alive and they have THOUSANDS of bad blocks. Didn't realized how bad it is because i was using these for RAID10 array and the data was rarely read. OS stopped booting, i was able to get most important data back. Don't buy these. Even cheapest SSDs are better. Slow but not silently failing.
