You could look at cloud type storage too, for backing things up
I have a similar setup as RussellZero, with a 250gb SSD for operating system, applications, games and an old style hard disk for data/storage. Important documents, files and photos etc get copied to both disks incase one dies. Running Windows from a SSD has been the biggest single performance upgrade I've seen in a while, it's just so much faster in loading things, from power on to Windows desktop in about 10 seconds. Hopefully reliability doesn't let it down though
