The main operating system was just a 256 gig SSD. I currently have a 500 gig in there now. I ordered a second one so I can put it in a raid so I don't have this problem again. Repurposing an old Dell tower from work. 

All the media was on the NAS, which is having no problems. 

 Won't RAID need 3 SSDs? I guess it depends on how you set it up.
