We kind of mentioned this in the conclusion of our 8TB HDD Seagate review here, Seagate has just been hit with a Class Action Lawsuit for the High Failure Rates of their 3TB HDDs.

(both internal and external) and Seagate's "inability to deliver non-defective hard drives that conform to their express and implied warranties". 

While Seagate has advertised their drives as "reliable" and "dependable" allegations have often been levied against the company that their drives have been some of the most unreliable on the market, with the Plaintiff claiming that the drives were "defective and failed prematurely at spectacularly – and in many respects unprecedentedly – high rates" and is taking action against the company both for himself and all affected consumers. 

        This is a class action arising from Defendant Seagate Technology, LLC’s (“Defendant”) repeated failure and inability to deliver non-defective hard drives that conform to their express and implied warranties; its breach of consumer protection, unfair competition and false advertising laws; and its unjust enrichment.

The class action lawsuit goes on to cite data from Backblaze as evidence against Seagate, with Backblaze having on several occasions reported that Seagate is among the worst manufacturer on the market who have failure rates that are often much higher than that of other manufacturers.

    As demonstrated by consumer experience and reports released by Backblaze, a data backup company, the true failure rate of the Drives was substantially higher than advertised, and the Drives did not last nearly as long as comparable devices from other manufacturers or even other models manufactured by Defendant.

 Right now Seagate is yet to respond to this class action Lawsuit. The Lawsuit can be found and read here.
