My hard drive situation is that I am a bit of a data hoarder.
For my PC, it's 1TB Samsung 970 Evo Plus SSD as the main OS drive. Then I have a 500GB Samsung 850 Evo SSD from my last computer. 4TB Western Digital Black Hard drive and 10TB Seagate hard drive.
My most common games go into my 1TB Samsung, my occasional games goes into my 4TB Western Digital and my backups go into my 10TB Seagate.
Eventually I would like to replace my hard drives with SSDs but that ain't happening for a long time considering how much space games take and SSD prices are still quite high for capacity. In Canada, a 4 TB Nvme SSD costs twice as much as a 14TB hard drive. I can wait for 30 more seconds for games to load than to wait 30 minutes if not hours for games to download with the increasing size requirements. Plus it's much faster to have the games on my hard drive and then move onto my SSD if I really like them than to redownload them.
