According to Backblaze , the company switched to Seagate 3 TB hard drives after the 2011 Thailand floods disrupted the supply of hard drives and increased their prices by 200 – 300 % . Backblaze , which normally used HGST 3 TB hard drives , were only able to find Seagate 3 TB drives in " decent quantity " . Backblaze noted that the failure rates of the ST3000DM001 did not follow a bathtub curve typically followed by hard disk drive failure rates , instead having 2.7 % failing in 2012 , 5.4 % failing in 2013 , and 47.2 % failing in 2014 . Other 3 TB hard drives that Backblaze placed in service in 2012 , which were operated in a similar environment as the Seagate drives , did not show signs of increased failure
