I know SSDs need to be powered on occasionally due to how they store data, which is why (also due to cost lol) I have most of my stuff on HDDs, though I know those can have issues if you leave them out unprotected.
Not much more I can do without spending a lot more money than I have already. But so far I've never needed to get my second backup.
Which reminds me I need to re-backup the second drive...
I can't hear the words "hard tack" without mentally going ":D clack clack"
