I have three systems available to use. My main desktop has 2 NVME SSD's, 2 SATA SSD's and 2 7,200 HDD's for storage. Once in a while I copy my files over to a secondary desktop with 2 NVME SSD's, 2 SATA SSD's, and one 10,000 rpm 74 gig Raptor. My third system isn't plugged in, but the box sits in my desk and it has an optical drive for burning or ripping disks, 1 NVME SSD, 2 HDD's, and 1 SATA SSD.
I backup everything regularly on my main PC and copy that to an external USB drive, and I also copy my files to the secondary desktop. Unless my house is nuked or burned to a crisp by an unexpected solar event, I should be able to recover all my pictures and files I wish to save forever.
