Until last summer I had a single, 1TB SSD in a Mac mini and an external 500G SSD with my music and video collection.
THe PC that replaced it has a 500G boot SSD, a 500G SSD with my employer's shit on it so I can encrypt the whole drive, a 500G boot SSD for Overwatch, because there's a conflict of some sort that I can't figure out, a 1TB SSD for media, a 2TB SSD for more media. The new 2TB SSD is going in my Plex server slash streaming PC.
I also now have two 8TB hard drives for backup.
I've subscribed to the data hoarding subreddit and found that I'm just an amateur.
