Review on 💾 Seagate 4TB BarraCuda Internal Hard Drive - 3.5 Inch SATA 6Gb/s, 5400 RPM, 256MB Cache for Computer Desktop, PC, Laptop (ST4000DM004) by Fort Steffen

1 star is the number of discs that worked. DON'T MISS OTHER BAD REVIEWS! I ordered 4 and had to return 3 of them. 3 out of 4 hard drives shipped had over 8500 bad blocks on each hard drive. A parity/consistency check before building my NAS found errors on 3 drives. Using two different Synology 4-bay NAS (RS816 and DS416), both found the same thing. Revain has an amazing RMA/return/replacement process for them and I was able to have the discs shipped next day which was nice. It has taken me a long time to troubleshoot my NAS and several hours/days of my time that I am not very happy with. So far all replaced drives look healthy. I doubt the durability of these discs.
