I have a file server with ~80tb of hard drives attached to it + 4tb of flash. It's kind of incredible. The first 4 drives were 6tb enterprise drives that cost $250 each (new). The most recent two are 14tb drives that I picked up for about $100 each (used). They're still going through their burn-in period before one gets data and the other becomes my new parity drive (unraid).

Everything other computer in the house is exclusively SSD.
