Make sure, if you use hardware RAID, you know what happens if your controller dies.
Is the data in a format you can access it easily? Do you need a specific raid controller to be able to read it in the future? How are you going to get a new controller if you need it?
That’s a big reason why people nudge you to software raid: if you’re using md and doing a mirror, then that’ll work on any damn drive controller on earth that linux can talk to, and you don’t need to worry about how you’re getting your data back if a controller dies on you.
Buy multiple drives, setup some sort of raid, setup some sort of backup. Then set up a 2nd backup.
Done.
All drives from all manufacturers are going to fail at more or less the same rate (see: backblaze’s stats) and trying to buy a specific thing to avoid the death which is coming for all drives is, mostly, futile: at the absolute best you might see a single specific model to avoid, but that doesn’t mean entire product lines are bad.
I’m using some WD red drives which are pushing 8 years old, and some Seagate exos drives which are pushing 4, and so far no issues on any of the 7 drives.
