These cheap drives, especially the 8TB Archive drives do have their uses such as BURST mining and cheap backup spinners.
The Seagate Backup Plus Hub 8TB model has these and also if you are in a country where your trading standards legislation does not suck, you can get a replacement free of any charges including delivery within a "reasonable" time. In the UK this is up to 6 years. By the time the drives fail (anywhere between 3 months to 6 years) there will be more reliable models available to anyone who returns a Seagate or any other manufacturer's drive.
If you're across the water in the USA you're out of luck for any retail protection outside the manufacturer's relatively short 1 or 2 year warranty (usually but some offer 3 to 5 years warranty on some drives and few retailers have a decent returns policy). They really aren't worth the risk to anyone in the USA, Canada or any other country where trading standards legislation is lacking any form of decent consumer protection.
For the UK and European countries with legislation worth the paper it's written on, go right ahead and grab a load when they are cheap and use your knowledge of the law and the RETAILER'S responsibility (do not approach the manufacturer under any circumstances even if the retailer tries to pursuade you to, even for the manufacturer warranty!) to take advantage of your rights under law to seek immediately remedy of either a repair or replacement free of any and all charges. BURST mining and Storj sharing should be fine even if these drives fail. For backup purposes though, make sure you have redundancy.
