Most Cost Effective External HDD

Hey everyone, I'm looking for the most cost effective external hard drive to store all my emulation gaming on. An 8TB to 12TB would be ideal. When I'm searching for the best GB/$ I start getting into the Seagate IronWolf products and the Exos. I thought these were predominately for servers or security systems. Some are NAS, some are RAID which are out of my purview. Can I still use them for the simple speedy storage devices that they are? Thanks.
