Amazon Renewed Hard Drives - Should you buy?

Video Description

In depth testing and analysis of Amazon Renewed/Refurbished HGST Ultrastar DC520 12Tb disks. What do you really get for your money when you buy these, what condition are the disks in and how much can you trust their reliability? I look at the condition, all the SMART stats, I run surface scans and full performance tests, and then I look at a large sample of public reliability data on these disks to assess how safe they are. I also show you to verify the drives, and when you should just return them.
