I buy all of mine used from random people via ebay. I’ve had a few DOA, and a few start throwing errors after a few years. No issues getting replacements or refunds from sellers within the warranty period. Never had one outright fail, nor have I lost any data from this.

I just checked and it turns out two of my drives are over 95,000 hours, that’s nearly 11 years! And they’re still going strong with no errors!
