It’s funny how it is the exact opposite for me.
All my WD drives died, while all my Seagate drives are in perfect working order.
Bought 2 WD hdds new, used them for about 4 years in RAID for daily borg backups, one died, the other got very slow with tons of smart errors.
Bought 2 Seagate hdds new, same usecase, same capacity, have been running for over 5 years now.
Personal anecdotes are not a reliable factor for manufacturer quality.
To quote some statistics:
In general, Seagate drives are less expensive and their failure rates are typically higher in our environment. But, their failure rates are typically not high enough to make them less cost effective over their lifetime.
