Failing drives with short lifetime

3 years ago I bought two Seagate IronWolf 4TB to use them in my Synology NAS.

One of them was dead-on-arrival and has been quickly replaced by Digitec.

Now, 3 years laters, 1 drive completly failed (according to Synology SMART test) and the second one is also failing with bad sectors increasing...

In summary, all my Ironwolf drives died. I will never again purchase an IronWolf disk and I replaced them with some WD Red Plus.
