I have it all on my SSD, and I use daily backups.
Before that, I used an HDD, with the same daily backups.
If you don't perform regular backups, then clearly you don't care about your
data, so why bother trying to distinguish if the HDD is ever so slightly
less untrustworthy than the SSD?
And if you do perform regular backups, then you only need your storage
media to be "reliable enough", so again the minute differences in
failure scenarios for HDDs and SSDs don't matter because both of them
are "reliable enough".
The differences are important, tho:
- SSDs are silent.
- HDDs are not silent.
- Some operations are much faster with the SSD (tho those don't
affect me very much, in practice, so it's not the main selling point).
- Oh, did I mention how little noise SSDs emit?
