did you update the firmware?Resurrecting this thread since my 1TB 870 EVO just approached death, date of production 10-07-2021 (as in 10th July 2021), at this date it has ECC Error Rate = 4625, with barely 8200 GB (TBW) and 5000 hours, maybe more units are affected than just the first half of 2021. That's sad, I used my warranty to get a new one, hopefully the new ones don't have any problems
Edit: date
