I run only used hgst. I have 6 x 3tb drives that are all 90k hour plus and I recently expanded to some new to me 12tb hgst. I always do badblocks test when I get the drive which took 4 days on the 12 tbs. One of them failed and I returned it to Amazon they shipped another and the replacement was perfect. If they package it poorly just return it right away and choose a different distributor.
