ST26000NM000C vs ST26000NM001C

These Seagate 26TB SATA drives are the same price from GoHardDrive’s eBay store, and both come with 5 year warranties.

The 00C is listed as being “Factory Renewed” and has “Exos” on the pictured drive label while the 01C is listed as being “Factory Recertified” and does not have “Exos” on the pictured drive label.

What are the differences (if any) between these models, and which should I buy?

I’m looking to buy 2 of these 26TB drives and then sell off 6 nearly 9 years old 8TB WD Red Pro drives I have in my home server.
