A few years ago, when I was about to purchase several TB+ size drives for building up my server & local hard drive storage capacity, I did some digging (on the internet) on brand & model reliability. There was not a lot of what I would call non-anecdotal data. Google did put out some data based on their experience.
Anyway, as I recall, leaving out the occasional batch problem, there were no significant differences across the brands.
Presently, there are only 3 manufacturers left in the business: WD, Seagate, and Toshiba. The diagram below is from wikipedia, and it somewhat misleads regarding Hitachi. While WD was required as part of the acquisition of Hitachi's hard drive business, to divest assets to Toshiba for 3.5" drives, WD's HGST subsidiary did retain some 3.5" product lines.
