The plural of anecdote is not data. The point of backblaze's publication is to share statistical data with the public at large. Their dataset doesn't include any WD Red drives, therefore, the data does not provide a statement about WD Red drives' reliability in either direction. Consider this: the least reliable drive in this dataset has a 2.7% annualized failure rate at an average age of almost 4 years. That's low enough that many SOHO users will never see a failure, yet high enough that a rack worth will have seen more than one failure recently. Thus, your question could be answered with complete honesty in both ways: with anecdotes by happy users and with anecdotes by unhappy users. Therefore, neither positive nor negative answers are useful to you. This phenomenon underlies the fundamental weakness of self-reported online reviews. You cannot actually get a useful measurement for how reliable a product is solely by self-reported sparse feedback.
