I don't have the number or quality of photos that I assume Coop has, but at this point I only use external hard drives. I'm currently using solid state ones for less chance of a moving part failure. I use the 1Tb size for portability. I have two filled with music, one full of photos, and one with movies. I can back the up cheaply, and store them in different locations. Cost is minimal, and 5+ Tb of cloud gets expensive.
Avatar is set of Loveless pattern drop point hunters with mammoth ivory scales by Tim Hartman, engraving and gold inlay by Ron Nott.
